What we do
Ten repairs we take on. Every coffee machine repair we offer has its own page: the part the technician actually swaps, how the job compares with the others on the list, and when an aging machine no longer earns the part.

In the order it gets done: the cheapest cause first, and the expensive answer at the bottom where it usually belongs.
A visit that brews and froths with you watching, reads the machine's own counters, then tests grinder, brew unit, pump and heater until one part is named.
Resealing, lubricating or replacing the brew unit that tamps the grounds and presses water through them, removable or fixed.
Clearing and renewing the burr grinder: jammed beans, a stone between the burrs, worn burrs, and the motor and gearbox that turn them.
Testing and replacing the pump that drives water through the coffee, with the flowmeter that counts each cup and the valves beside it.
Diagnosing and replacing the thermoblock or boiler that heats water for coffee and steam, with its sensor and thermal cutout.
Restoring the froth: the milk tube, the frother, the air inlet, the milk valve and the cleaning cycle that keeps them clear.
A thorough descale of the water path and heater, a fresh filter, hardness set to match your water, and a message that clears.
The water side: the inlet valve, supply line and drain hose of a plumbed built-in, or the tank valve and level sensor.
Testing and replacing the power board, control board and touch panel of a coffee machine, and the sensors they read.
Finding where water or steam escapes inside a coffee machine and renewing the O-rings, gaskets and hose clips that should hold it.
Before you bookBands rather than prices, because nobody can quote a figure before the coffee machine has been looked at — and the diagnostic visit that decides it, set against the repair.
10 repairsCheapest firstDiagnostic visit Read the cost guideWeigh the repair against what a new coffee machine of the same kind would really cost you, fitted and working, not only its shelf price. A built-in needs a model that fits the same cabinet opening, trim and rails, and a plumbed one also needs its line and drain set up again; that tips most built-ins firmly toward repair. Seals, a descale, a frother, a sensor or a tank valve are small beside a new machine, and a brew unit, a grinder or a pump is usually still worth it. The one real exception is an entry-level countertop machine that needs a board, a heater and a pump together: there the technician lays both totals side by side and the choice is yours.
| Repair | Relative cost | Notes |
|---|---|---|
| Brew unit seals, lubrication, drive gear or a complete brew unit | low to moderate | New piston seals and the maker's grease on a unit that slides out are near the bottom of this band. A worn drive motor on a fixed unit, or a whole new brew unit that is sold only as an assembly, sits one step higher. |
| Burrs, grinder motor, gearbox or dosing sensor | moderate | Clearing bridged beans and fitting a fresh pair of burrs is the lighter end. A grinder motor with its gearbox, or a complete grinder assembly after a stone cracked the carrier, is at the top of the band. |
| Vibration or gear pump, flowmeter, check valves and hoses | moderate | A clogged flowmeter or a sticking check valve is the modest part of this row. A new pump, fitted with fresh hoses and clips, and a descale of the path it pushed against, makes up the fuller job. |
| Thermoblock or boiler, heat sensor and thermal cutout | moderate to highest | A thermal cutout or a heat sensor on its own is a small part. A new thermoblock, or a pair of them on a machine that heats coffee and steam apart, climbs to the top, and the old scale has to be cleared from the rest of the circuit at the same time. |
| Milk tube, frother, O-rings, milk valve and steam path | low to moderate | Clearing dried milk and fitting a new tube and O-rings costs little beyond the visit. A replacement frother head, a milk valve or a scaled steam valve behind it moves the job up a step. |
| Full descale, water hardness set-up and a fresh filter | lowest | A complete descale through every path with a new filter cartridge is the smallest job here. Valves or a heater passage so choked that they need clearing by hand add time to it. |
| Tank seat valve and sensor, inlet valve, supply line or drain hose | low to moderate | A tank float, a seat valve or a cleared inlet screen is a small part and a short visit. A new inlet solenoid, a fresh supply line or drain hose on a plumbed built-in, with the machine drawn forward to reach them, sits a step higher. |
| Power board, control board, display or touch panel | moderate to highest | A loose plug, a corroded connector or a single sensor that made the board look guilty costs little. A new control board or display for a built-in is among the dearest parts in the machine, and one for an imported model can take time to arrive. |
| O-rings, gaskets, hose clips and the brew unit drain valve | low | Seals and clips are inexpensive parts; most of the cost is the time spent drying the machine and tracing the water to its joint. A cracked tank or a drain valve on a fixed brew unit adds a little to it. |
Most people arrive knowing the symptom, not the repair. These are the jobs each one usually turns out to be, cheapest first — and every one of them starts with the coffee machine diagnostic visit.
