Brew piston
On C-1 we rinse the brew unit dry, then grease the guides — a thin bitter shot is a stuck piston, quoted before new seals.

Coffee machine repair in C-1: a thin stream, no milk froth, or a false descaling alert — the technician opens the brew unit and pump.
On Philips and Krups we pull the brew piston and grease the guides first, then calibrate flow.
In C-1 panel kitchens empty the tank and leave access to the side cover of the station.

How the visit works
On C-1 we rinse the brew unit dry, then grease the guides — a thin bitter shot is a stuck piston, quoted before new seals.
No milk foam: milk valve first, then the air channel, then the frother — reverse of a blind rinse.
False Philips and Bosch descaling alerts are cleared by flushing the boiler and calibrating the flow sensor.
Topic 1 / 3

The technician cleans the brew unit, hydraulic system, flushes the grinder and checks seals. After the service the machine runs quieter and coffee tastes richer.
