More moving parts than anything else in the kitchen, which is why so many calls end in cleaning and adjustment rather than components. ### Scale, which is the local subject Hard water narrows every passage in a coffee machine and it does it quietly: the shot gets slower, the temperature drops a little, the milk gets less reliable, and one day the machine refuses to run until it is descaled. A machine in daily use here needs the routine more often than the manual implies, and that is not a defect in the appliance. ### What we are actually called out for - **Slow or weak extraction** — grind, then scale, then the brew group. - **Descale cycles that do not satisfy the machine** — routine, filter, water setting, then the sensor. - **Milk systems that have stopped** — cleaning first, and it is usually enough. - **Leaks,** which on a plumbed machine may not be in the appliance at all. ### What the repair costs Coffee maker work starts at $185. Where a descale, a grind adjustment and a milk-path service is the whole answer — which is often — that is the job and it is priced as one. What this involves Grind and scale checked before any pump is quoted The milk path cleaned properly before it is called failed Plumbed and reservoir machines diagnosed differently Establish plumbed or reservoir A plumbed machine brings a supply, a valve and possibly a filter into the diagnosis, and a leak may be behind the cabinetry rather than in the appliance. A reservoir machine keeps everything in front of you. Grind, then scale A grinder that has drifted finer, or an oilier bag of beans, will choke the brew group; scale narrows every water passage and cuts what the pump can deliver. Both are maintenance rather than repair, and both come before anybody quotes a component. Clean the milk path properly Milk residue sets hard inside narrow tubes and it is what punishes neglect fastest. A great many "the milk system has failed" calls end with a proper clean, and it is worth trying before the visit. Then the components Brew group, pump, boiler, steam valve — measured, once the maintenance answers have been eliminated. And a shot pulled and a milk drink made before the visit ends. One machine, six systems A grinder, a brew group that compresses and ejects a puck several times a day, a pump, a boiler, a water path and a milk path.

What the repair costs Coffee maker work starts at $185. Where a descale, a grind adjustment and a milk-path service is the whole answer — which is often — that is the job and it is priced as one. ### The coffee has got slow and weak. Almost always the grind and the scale, in that order. Try a slightly coarser setting and run a proper descale before anybody quotes you for a pump. If the machine has been descaled recently and the grind is right and it is still slow, then the brew group or the pump is a real conversation. ### It keeps asking to be descaled and I keep descaling it. Then either the routine is not reaching everything or the water is winning. South Florida water is hard enough that a machine used several times a day genuinely needs attention more often than the manual suggests. Check the descaler is the right kind, that the cycle is allowed to finish, that the filter is being changed rather than fitted once, and that the water hardness setting matches what you actually have. ### The milk system will not froth. Run the cleaning cycle, then take the frother apart as far as it is designed to come apart and soak the pieces. Milk sets hard in narrow tubes and this is where most of these calls end. If it is genuinely clean and still will not froth, the steam valve, the pump or the air intake is the repair. ### Is one machine in the line worth a repair service? Yes, and for a specific reason: a built-in coffee maker is fitted into cabinetry with the rest of the kitchen, so replacing one is a joinery job with a lead time rather than a purchase. On this appliance more than most, keeping a working machine working is worth more than the part costs. --- **[Read full article: Built-in coffee maker repair](https://bertazzonimiami.support/services/coffee-machine-repair/)**
