A new coffee machine setup checklist for the first week is not “unbox, brew, and hope.” Day 0 is wash, water, and a factory flush with no coffee in the path. Days 1–3 are one-variable dial-in so you know whether a bad cup is the recipe or a real fault. Day 7 is locking a care habit you will actually keep. Stop for leaks, a burn smell, or no water. Keep going for sour, bitter, weak, or uneven cups—those are taste issues, not day-one failure.
This page is the first-week owner SOP that sits under our coffee machine ownership guide. Button-by-button brewing lives in how to use a coffee machine (and the espresso sibling). Long-term cleaning lives in coffee machine maintenance and the coffee machine care calendar. If you are still choosing a category, pause on this page and use the short bridge in coffee machine types—then come back once the box is open.
Takeaway: Treat week one as three jobs—flush the factory, establish a repeatable cup, then install a tiny care habit—not as a hunt for café-perfect espresso on night one.
Who This First Week Coffee Machine Checklist Is For (and Who Should Skip)
Who it’s for: anyone who just unboxed a drip maker, capsule machine, semi-automatic espresso machine, or bean-to-cup unit; gift recipients who do not want to ruin the first bag of beans; households sharing a new machine who need one posted sequence; and owners who already brewed once, hated the cup, and are about to return hardware that only needed a flush and a calmer dial-in.
Who should skip: shoppers still comparing categories or budgets—this is not a buying guide. Owners hunting a full brew tutorial (dose, tamp, ratio, milk texture) should open the use guides instead of duplicating them here. Anyone whose machine is already months old and tasting dull should jump to maintenance, descaling, or troubleshooting rather than “setup.” If you smell burning electronics, see water under the base, or get no flow after a seated tank, stop this checklist and treat it as a fault, not a flavor project.
Takeaway: Stay here if the machine is new and the job is “first seven days without creating a mess.” Leave if the job is shopping, café technique, or repair.
First-Week Timeline at a Glance
Most manuals dump unboxing, first brew, and “clean regularly” into one afternoon. That is why people either never flush, or they change grind, dose, temperature, and beans on the same morning and decide the machine is defective. Use this timeline as the spine of your first week coffee machine routine.
| Phase | When | Owner job | Done when | Do not do yet |
|---|---|---|---|---|
| Day 0 — Flush | Unbox day, before coffee | Place, wash parts, set water, run water-only cycles | Water runs clear, no packing smell in the cup path, no leak at rest | Dial-in, guest lattes, oil-heavy beans, descaling “just in case” |
| Day 1 — Baseline cup | First real coffee | Brew one standard drink with default settings; discard if plastic-tasting | You have a written note: time, dose or pod, volume, taste in 5 words | Changing three variables, buying a new grinder, blaming the boiler |
| Days 1–3 — Dial | Next 2–6 drinks | Change one variable per session; stay on the same beans or pod line | Two similar cups in a row you would actually drink | Full recipe overhaul, competing “pro” settings from forums |
| Days 4–6 — Repeat | Normal household use | Same water, same beans, same morning sequence; add milk only if daily | The machine feels boring to operate; tray and tank have a home | Skipping rinse because “it’s new”; overnight milk in the carafe or wand |
| Day 7 — Care habit | End of week one | Lock daily empty/rinse/wipe plus a weekly wash reminder | A 3-line habit you can keep without a spreadsheet | A 12-step café SOP nobody in the house will follow |
Typical time budget: Day 0 takes 20–40 minutes. A baseline cup takes one brew cycle plus two minutes of notes. Dial-in across Days 1–3 is 10–20 minutes per session, not an all-day project. Day 7 is a 10-minute reset: empty, wash what you can remove, and put the care reminder where you will see it. If any session hits a stop gate in the next section, the clock pauses until the machine is safe.
Takeaway: Flush before flavor. One variable at a time. Habit on Day 7, not a maintenance encyclopedia.
Stop-and-Fix Gates vs Keep-Going Taste Issues
Week one fails when people treat every bad cup like a broken pump—or treat a leak like “it will settle.” Split symptoms into two buckets before you touch grind or strength buttons. Full trees live in coffee machine troubleshooting; this table is only the first-week gate.
| Signal | Bucket | What to do in week one | What not to do |
|---|---|---|---|
| Water under the base, drip from a seam that is not the tray, or a puddle after a cycle | Stop and fix | Unplug. Empty tank. Do not run another cycle. Photograph the leak, reseat tank and tray once, then contact support if it returns | Keep brewing “to see if it seals”; park towels and ignore it |
| Burning plastic, hot electrical smell, smoke, or scorching insulation odor—not roasted coffee | Stop and fix | Power off, unplug, ventilate. Do not open the chassis. Factory residue smell after a water flush is milder and fades; burning electronics does not | Run more flushes to “burn it off” |
| No water movement: pump silent, or pump screams/hums with a dry group and empty-looking path | Stop and fix | Confirm power, tank seated above the intake, and a water-only rinse. If still dry, treat as airlock or interlock—not as a grind problem | Add coffee, a capsule, or a puck to “force” flow |
| Repeated error lights after tray, grounds bin, door, and brew group are seated | Stop and fix | Power cycle 30–60 seconds; reseat sensors; check the manual’s first-run interlocks. Still looping? Pause setup | Hold the start button until something gives |
| Outlet trips, plug is hot, or the machine will not power from a known-good socket | Stop and fix | Stop. Try one other outlet on a different circuit once. If it trips again, do not keep testing | Use an extension cube or a wet counter as a workaround |
| First cups are sour, bitter, weak, thin, or hollow | Keep going (taste) | Finish Day 0 flush if you skipped it; then change one recipe variable per brew on Days 1–3 | Return the machine after two bad lattes |
| Channeling, fast blonding, pale crema, or uneven drip from a portafilter | Keep going (taste / prep) | Stay on the espresso use path: distribution, dose, grind. Confirm the basket type before buying new gear | Assume the pump is “not 9 bar” |
| Mild packing or “new appliance” smell that fades after water-only cycles | Keep going (setup) | Continue Day 0 flushes until the cup path smells like hot water, then brew a throwaway cup | Confuse this with a burning-electronics smell |
| Slow drip on a brand-new machine with a heavy dose or very fine grind | Keep going first; stop if water-only is also slow | Run water-only. If water-only is healthy, coarsen or reduce dose. If water-only is a trickle, pause and check scale/clog/filter install | Descale on day one “because the internet said so” |
A practical smell test: factory film and new-hose odor are faint, watery, and improve after 1–3 rinses. A burn smell is sharp, persistent, and often worse when the heater kicks in with no brew. When in doubt, unplug. Taste problems never require you to ignore water on the floor.
If the hydraulic path is dead—no water with coffee out of the way—you are not in the dial-in phase. If water flows and coffee tastes wrong, you are. That split saves more machines from returns than any grind chart.
Takeaway: Leak, burn smell, no water, looping errors, and tripped power are stop gates. Sour, bitter, weak, and messy shots are week-one homework.
Day 0: Unbox, Place, Wash, Water, Flush
Day 0 has one success metric: a clean water path and a machine that sits where heat, steam, and spills will not punish it. You are not chasing flavor. You are removing packing dust, checking that water moves, and choosing water you can live with for seven days. The full first-brew button sequence is in how to use a coffee machine; use the list below as the owner checklist, not a second tutorial.
Placement and power (5–10 minutes)
Set the machine on a level, heat-safe counter with the drip tray fully inserted. Leave the clearance the manual shows for rear and side vents—typically a few centimeters, more if the unit dumps steam backward. Keep it away from the kettle’s steam plume and the stove. Confirm the plug matches the outlet; do not start week one on a cheap multi-plug cube if the machine is a high-wattage espresso or bean-to-cup unit.
Open the box with the machine upright. Remove tapes, cardboard, silica packs, and any transit bolts or brew-group locks the manual flags. Semi-auto owners should lay out portafilter, baskets, tamper, and cleaning tools before the first power-on so you are not hunting a basket while water is heating. For a labeled map of those parts, use espresso machine components rather than guessing from marketing photos.
Wash what you can remove (8–12 minutes)
Wash the tank, lid, drip tray, carafe, filter basket, and any milk carafe in warm water with a drop of mild soap. Rinse until there is no film. Do not put sealed electronics, the brew group (unless the manual says it is removable and dishwasher-safe), or a portafilter handle with a plastic coating into a dishwasher on day one unless the manufacturer says so. Dry the tank rim so the lid sensor does not false-alarm.
Capsule machines: rinse the capsule bucket and drip tray even if they look clean. Drip machines: rinse the brew basket so paper filters do not pick up packing dust. Bean-to-cup: empty the grounds box and check that the brew group (if removable) seats with a click after a rinse—do not oil it unless the manual requires a specific lubricant.
Water for week one (2 minutes + a hardness guess)
Fill with fresh cold water. If your kettle already grows white crust in a week or two, do not start this machine on raw hard tap “just for setup.” Use the same filtered water you plan to keep using, so Days 1–3 are not a moving target. Avoid distilled-only or aggressive RO with no minerals as daily boiler feed; it can taste flat and is a poor long-term choice for many machines. If you need a hardware decision—pitcher vs tank cartridge vs inline—open coffee machine water filter guide after Day 0, not in the middle of the first flush.
Install any included water filter only after soaking or priming it as the insert says. A dry cartridge can airlock a new pump and look like a dead machine. If the model asks for a hardness test strip, do it on Day 0 and save the result; you will need it for later descale intervals, not for today’s flavor.
Factory flush (5–15 minutes)
Run water-only cycles until the stream looks clear and smells like hot water, not packing. Typical range: one to three brew or rinse cycles on drip and capsule; a group flush plus hot-water wand purge on semi-auto; the built-in rinse plus one water-only drink program on bean-to-cup. Discard that water. Do not put coffee, a capsule, or a puck in the path until this is done.
If the pump hums and nothing moves, reseat the tank so the intake hose is submerged, then try a hot-water or steam purge if the machine has one. That is still Day 0, still a stop-adjacent check—not a reason to add coffee. If water-only flow is healthy, you have passed the hydraulic gate.
| Day 0 checkpoint | Pass | Fail → |
|---|---|---|
| Counter and vents | Level, tray in, vents clear, no stove steam | Move the machine before you flush |
| Removable parts | Washed, rinsed, seated | Do not heat soap residue in the tank |
| Water | Fresh, not distilled-only; filter primed if used | Fix water before blaming taste on Day 1 |
| Water-only flow | Clear stream, tank level drops, tray catches drips | Stop-and-fix: no water / leak table above |
| Smell | Faint new-appliance odor fading | Burn smell → unplug |
Takeaway: Day 0 ends when water moves cleanly and the machine is dry around the base. Coffee starts on Day 1.
Day 1: First Real Cup and a Written Baseline
Brew one ordinary drink the machine was designed for: a full carafe or a mug on drip, one labeled capsule, a standard espresso on semi-auto, or the default coffee button on bean-to-cup. Use reasonably fresh coffee—roasted within the last few weeks for beans, in-date pods for capsules. If the first cup tastes like hot plastic or cardboard, throw it out and brew a second. The second cup is the baseline, not a verdict on the brand.
Write five facts: machine type, water source, coffee (bag date or pod name), setting (grind / strength / volume), and taste in plain words (“sour + thin,” “bitter + dry,” “fine, a bit weak”). You need that note because Days 1–3 only work if you can see what you changed. Skip milk on cup one unless the household will never drink it black; milk hides extraction mistakes and trains you to chase foam instead of coffee.
If Day 1 hits a stop gate—leak, no water, burn smell—do not “finish the shot.” If Day 1 is merely disappointing, you are on schedule. Move to the branch checklist for your type. Do not start a second machine category’s workflow on the same unit.
Takeaway: One standard drink, one note. The first cup is data, not a product review.
Days 1–3: Dial by Machine Type (Branch Checklists)
These branches are week-one checklists: what to confirm, what one lever to move, and when to stop. They are not replacements for the use guides. If you need the full sequence—filter fold, tamp, steam order, brew-group lock—open the linked article and come back to this list with a pen.
Stay on one coffee for these three days. Switching beans or pod lines every drink makes dial-in impossible. Bean shopping belongs in the coffee beans guide after you have a baseline, not during it.
Drip / filter coffee maker
Week-one job: a clean paper (or permanent) filter path, a medium grind, and a brew that finishes without a stall. You are not trying to win a pour-over competition.
| Check | Week-one action | If it fails |
|---|---|---|
| Filter seated | Paper fully open in the basket; permanent filter rinsed | Overflow / grounds in the carafe → reseat, reduce dose |
| Dose vs carafe size | Use the scoop or gram range on the bag for the water you actually brew—not a “max basket” vanity fill | Bitter sludge → less coffee or coarser grind; weak tea → more coffee, not a hotter rumor setting |
| Grind | Medium, like sand—not espresso dust, not French-press boulders | Stall or overflow → coarser; sour and thin → slightly finer or more dose |
| Water-only still healthy | If a coffee brew crawls, run a water cycle | Water-only slow → stop-and-fix / troubleshooting, not more coffee in the basket |
| Hot plate / thermal carafe | Do not “fix” bitterness by sitting on a hot plate for an hour | Brew what you will drink in 20–30 minutes, or use a thermal carafe |
Change one thing per pot: dose or grind, not both. Pause milk and flavored syrups until two pots taste like coffee you would serve a guest. Detailed brew steps: how to use a coffee machine.
Capsule / pod machine
Week-one job: rinse cycles, correct capsule seat, and a size button that matches the pod. You cannot grind a capsule. Most “weak pod” complaints in week one are extra-large volume on a lungo button, a used pod left in the chamber, or skipped flushes.
| Check | Week-one action | If it fails |
|---|---|---|
| Chamber dry and empty | Eject any demo or stuck capsule before the first real drink | Error or no flow → empty, rinse, reseat lever |
| Pod brand / size match | Use capsules the head is designed for; do not force a third-party pod that will not seat | Leak at the head or puncture fail → stop, do not hammer the lever |
| Volume button | Start with the short drink the capsule was made for | Watery cup → smaller volume, not a “stronger” myth cycle on the same large size |
| Used-pod bucket | Empty daily in week one so the sensor does not halt a flush | Mystery stop mid-week → tray and bucket sensors first |
| Milk adapter (if any) | Skip until black coffee is acceptable; then rinse the adapter after every milky drink | Sour smell by Day 4 is milk film, not a bad capsule line |
If water-only rinses are strong and a seated genuine capsule still will not brew, that is a stop-adjacent interlock or puncture issue—use troubleshooting, not a second box of random pods.
Semi-automatic espresso
Week-one job: hot group, a weighed dose in the correct basket, and a shot you can repeat twice. You are not building a café menu. Portafilter technique and steam order live in how to use an espresso machine. This checklist only keeps week one from turning into a parts-buying spiral.
| Check | Week-one action | If it fails |
|---|---|---|
| Basket type | Know if you are on a pressurized (dual-wall) or non-pressurized basket | Pressurized + very fine grind often chokes; non-pressurized + blade-grinder dust often channels. Fix match before buying a new machine |
| Warm-up | Heat until the ready light is honest; flush the group; warm the portafilter | Sour, thin first shot after a cold start → wait, do not open the grind all the way |
| Dose | Weigh within the basket’s typical range (often ~14–18 g for a double, check your basket) | Spray or no seal → reduce dose / check gasket seating; hockey-puck dry and tiny yield → dose or grind, not a “15 bar” panic |
| One lever per shot | Change grind or dose or yield, not all three | Chaos notes → go back to yesterday’s settings and change one number |
| Steam wand | Purge, steam, wipe, purge. Never leave milk to dry overnight | Wand smell by Day 3 is hygiene, not beans |
| Puck and tray | Knock, rinse basket, empty tray before it floods the pump area | Base moisture → stop-and-fix leak check, not a stronger tamp |
Crema on day one is not a quality score. Pale, fast shots after a proper warm-up are usually grind/dose/distribution. If the group runs water-only in a healthy stream and the machine does not leak, stay in the keep-going bucket. If you need named parts—shower screen, gasket, solenoid symptoms—use the components guide and troubleshooting, not a week-one teardown.
Bean-to-cup / super-automatic
Week-one job: hopper filled with suitable beans, rinse cycle understood, strength and volume set to a drink you will finish, and the grounds bin emptied so sensors stay honest. You are not mapping every menu tree.
| Check | Week-one action | If it fails |
|---|---|---|
| Beans in the hopper | Whole beans only; avoid extremely oily dark roasts that smear a new grinder | Grinder stall or paste in the chute → stop, clear per manual; switch bean style after a clean |
| Rinse / idle rinse | Allow the automatic rinse; put a cup under the spouts | Skipping rinses in week one trains a stale path before you have a baseline |
| Strength vs cup size | Start mid strength and a mug-sized volume, then move one step per day | Huge cup + max strength as a first experiment hides whether the brew group is even packing |
| Grind setting (if user-facing) | Change one notch, then brew 2–3 drinks before another change—burrs lag | Immediate second change → you will never know which notch worked |
| Brew group and bins | Empty grounds and tray daily; reseat the brew group if the manual has you remove it | Error loop → sensors and seating (stop-and-fix), not a new bean bag |
| Milk system | If you drink milk drinks daily, run the machine’s milk rinse the same day. If not, leave milk for Day 4+ | By-the-weekend sour milk smell is a care miss, not a defective thermoblock |
Oily beans, a full grounds drawer, and a too-large cup are the usual week-one “this super-auto is weak” cluster. Water-only rinse from the spouts should look like a steady stream. If that stream is missing, you are in the no-water gate, not the flavor menu.
Takeaway: Each type has one or two levers in week one. Use the dedicated how-to for the motions; use this page to keep those motions inside a seven-day plan.
Days 4–6: Repeatability, Water, Beans, and Milk
If Days 1–3 produced two cups you would drink, do not invent a new recipe because a video said so. Days 4–6 exist to make the sequence boring: same water, same coffee, same rinse-before-brew habit, same shutdown wipe. Boredom is the goal. That is when you notice a real fault instead of a moving recipe.
Keep the water story still
Do not bounce between tap, pitcher, and bottled water in the same week. Pick one feed. If chlorine is obvious, a simple carbon pitcher is enough for many kitchens. If the kettle scales fast, plan a proper filter path using the water-filter guide—but install it as a dedicated short session, then flush again, rather than mid-carafe. You are still not due a preventive descale on a brand-new, in-spec machine unless the manual’s first-run wizard demands a hardness setting or a rinse reagent. When scale actually appears later, use how to descale a coffee machine—not vinegar experiments on day five.
Keep the coffee story still
Finish the bag or sleeve you started. If the cup is harsh, check roast date and grind match before you buy a “better” origin. Light, very fresh espresso roasts can taste sharp on a still-learning semi-auto; that is a keep-going taste issue. Stale supermarket beans can taste flat on a perfectly flushed drip machine; that is also not a heater defect. Capsule users: finish one sleeve of the same blend at one volume before mixing flavors.
Add milk only if it is a daily drink
If the household drinks black coffee, skip steam pitchers and milk carafes until Day 7. If cappuccinos are the reason you bought the machine, add milk on Day 4 with a rule: purge and wipe every time, and never leave dairy in a carafe overnight. A sweet, sour, or gym-bag smell by the weekend is almost always milk protein, not “new machine gassing off.” That smell is a care miss you can still fix in week one; it is not automatically a stop gate unless it comes with a burn/electrical odor.
Household rules worth posting
Put three lines on a note on the tank or hopper: (1) empty tray and grounds before they click full, (2) no oil-slick beans in a new super-auto hopper, (3) if water appears under the base, unplug—do not make another drink. Shared kitchens fail week one when the second user skips the rinse and the third user assumes the error light is “just how it is.”
Takeaway: Days 4–6 lock sameness. Change water, beans, and milk only on purpose, one at a time, never because you are bored.
Day 7: Install a Care Habit (Not a Full Calendar)
Day 7 is not a deep clean festival and not a descale. It is the moment you decide what will happen every morning so week two does not smell like week-old tray water. Copy a tiny habit, then let the long calendar live elsewhere.
| Habit | What “done” looks like | Typical time | Where the rest lives |
|---|---|---|---|
| Daily empty | Drip tray and grounds or used pods are empty; no standing milk | 1–2 min | Maintenance hub |
| Daily rinse / wipe | Group, basket, spouts, or wand wiped; bean-to-cup rinse allowed to finish | 1–3 min | Type use guide you already followed |
| Tank topped with the same water | You did not invent a new water source today | 30 sec | Water filter guide if hardness is the issue |
| Weekly wash (schedule it today) | Removable parts get soap and a full rinse once this coming week | 10 min | Care calendar |
| Hardness note saved | Strip result or “kettle scales in ~X days” written once | 1 min | Descale article when the calendar says so |
If you want a printed weekly / monthly / quarterly grid, that is the care calendar’s job. If you want chemical vs tablet vs backflush distinctions, that is maintenance. Day 7 only asks whether you can name the daily empty, the daily wipe, and the first weekly wash. Owners who skip this step keep treating every later fault as “setup never finished,” which is how a six-month-old tray becomes a smell complaint that looks like a defective heater.
Do a 60-second safety recap on Day 7: dry base, honest power cord, no stored extension-cube heat, hopper lid closed, and no forgotten capsule in the head. If anything fails the stop-gate list, you do not “complete” week one—you open troubleshooting or support.
Takeaway: Day 7 success is a habit you will keep on a busy Monday, not a binder of café SOPs.
What “Good Enough” Looks Like by Day 7
Week one is successful if all of the following are true. It does not require Instagram crema or a calibrated water recipe.
- Water-only flow works and the base stays dry during normal drips into the tray.
- You can brew the household’s standard drink without reading the box.
- Two cups in a row were acceptable on the same coffee and water.
- Tray, grounds, or pods have a daily empty home.
- Milk path (if used) has been rinsed the same day it was used.
- You know whether a future bad cup is a stop gate or a taste lever.
If the cup is still only “fine,” that can be the machine’s ceiling on pressurized baskets, capsules, or a cheap blade grind—not a failed setup. Setup promised a clean, repeatable path. It did not promise a café. Improving grinders, baskets, or beans is a later purchase decision; do not smuggle it into Day 2 as a warranty claim.
Takeaway: Repeatable and clean beats impressive and chaotic. Impressive can wait until the habit exists.
Common First-Week Mistakes
These are the patterns we see when a new machine gets blamed for owner-sequence problems. None of them require a new SKU on day two.
- Skipping the factory flush and scoring the first cup as “cheap plastic.” Flush, discard, then judge.
- Changing grind, dose, temperature, beans, and cup size in one morning. You cannot learn from that. One lever per session on Days 1–3.
- Treating sour or bitter as a broken pump. Those are keep-going taste issues after water-only flow is proven.
- Ignoring a small leak because “new seals settle.” Water under the base is a stop gate.
- Running distilled water because it sounds pure. Use it only if the manufacturer allows it and you have a mineral plan; otherwise pick a stable filtered tap.
- Descaling on day one with kitchen vinegar. New machines need a flush, not an acid bath, unless the manual’s startup wizard says otherwise.
- Oily beans in a new super-auto hopper because the bag said “espresso.” Paste in the grinder is a week-one own-goal.
- Leaving milk in the wand or carafe overnight and calling the smell a defect on Saturday.
- Force-fitting capsules or overfilling a portafilter until something leaks, then brewing again to test the leak.
- Using week one to comparison-shop a different machine type instead of running this checklist. If you truly have the wrong category, stop and read types—do not keep pulling shots on hardware you already plan to return without a fair flush-and-baseline.
- No notes. Without a five-word taste line, every cup feels like a new crisis.
- Hot-plate babysitting on drip machines, then blaming bitterness on “the heating element.”
Takeaway: Most week-one returns are skipped flushes, stacked variables, or ignored leaks. Fix the sequence before you fix the SKU.
Soft Next Step If You Still Need a Machine
If this checklist made it obvious you unboxed the wrong category—capsule when you wanted fresh beans, or a semi-auto when nobody in the house will tamp—stop mid-week rather than building a resentful ritual. That decision is shopping, and it is out of scope here. Browse coffee machines after you know which type you will actually maintain. Then return to the ownership guide so week one on the replacement unit is shorter than this one.
FAQ: New Coffee Machine Setup Checklist
How long should a new coffee machine setup checklist take on day one?
Plan 20–40 minutes for Day 0 (place, wash, water, 1–3 water-only flushes) and one extra brew cycle for the first real cup. That is the whole “day one” job. Dial-in is spread across Days 1–3 on purpose so you do not stack variables. If Day 0 takes more than an hour, you are probably mixing in recipe work or a filter-shopping rabbit hole—pause those until water flows clean.
Can I drink the first cup from a new coffee machine?
You can, but it is a poor baseline. Factory film and packing dust are why manuals want water-only cycles. Brew those, discard, then brew coffee. If that coffee still tastes like plastic, discard it too and brew a second. Judge the machine on the post-flush cup, not on the water that sat in new hoses for the first two minutes.
What should I do in the first week with a coffee machine if it tastes bad but water flows?
Stay in the keep-going bucket. Confirm you flushed. Stay on one coffee. Change one lever per drink using the branch checklist for drip, capsule, semi-auto, or bean-to-cup. Do not descale as a flavor hack and do not open the chassis. If water does not flow, or you have a leak or burn smell, leave this FAQ and use the stop-and-fix table plus troubleshooting.
Do I need to descale a brand-new machine in week one?
Usually no. Week one is flush and habit, not acid. Descale when hardness, slow water-only flow, or the manufacturer’s interval says so. A new unit with healthy water-only flow does not get better because you ran vinegar through it on day two. Save the hardness strip result on Day 0 so the later calendar is based on your water, not a generic “monthly” guess.
When is a bad first week a warranty issue instead of setup?
When a stop gate remains after the obvious seating checks: tank locked, tray in, brew group or portafilter seated, primed filter, known-good outlet—and you still have no water, a leak from the body, a burning electrical smell, repeated breaker trips, or error loops. Document with photos and stop brewing. Taste you dislike after a proper flush and a calm one-variable dial-in can still be a mismatch (basket type, capsules, beans), which is a keep-going or shopping problem, not automatically a dead heater.
What to Read After Week One
Keep this page as the seven-day spine. For daily buttons and brew order, use how to use a coffee machine or how to use an espresso machine. For parts names on a portafilter machine, use espresso machine components. For cleaning intervals, use coffee machine maintenance and the care calendar. For scale, use how to descale. For symptoms, use troubleshooting. For water hardware, use the water filter guide. For bags and roast dates, use the coffee beans guide. The hub that ties those jobs together is the coffee machine ownership guide.
Next physical action: if you have not flushed yet, do Day 0 before another flavored drink. If you have flushed and the cup is uneven, pick your type branch and change one variable tomorrow morning. If the base is wet or the smell is burn, stop.
