About the service
I service espresso machines in homes and small offices, and most calls start with the same handful of complaints: the stream went weak and the cup fills forever, the pump howls but pushes no water, a puddle shows up under the body by morning, or the grinder stops biting the beans and the motor just spins. None of that means the appliance is finished. In nine cases out of ten the cause is scale in the water circuit, a brew unit that has never been washed properly, or a rubber ring that has gone hard and flat.
I begin with diagnostics on the spot: I measure the flow, listen to the pump, inspect the drip tray and the whole water path, and check the temperature of the drink in the cup. Before a single panel comes off, the appliance is unplugged from the mains and the tank is drained — inside these machines water and live wiring run centimetres apart, which is exactly why stripping one down is a job for a technician and not for a kitchen screwdriver. I also warn you in advance, before any work begins: opening the housing may void the factory warranty, so if the machine is still covered we discuss that first and the decision stays with you.
What a visit includes:
— full disassembly and washing of the brew unit, then regreasing the guides and pistons with food-grade lubricant only;
— descaling the boiler and the water lines with food-safe agents used strictly per their instructions, always followed by rinsing cycles until the water runs clear and odourless;
— replacing worn O-rings, gaskets and non-return valves, the usual cure for a leak from below;
— grinder service: burr cleaning, grind adjustment and brewing temperature setup so the shot tastes right again;
— prevention: one service a year plus a water filter costs far less than a new hydraulic group.
Before I arrive, switch the machine off, leave the tray and the spent pucks as they are, and please do not pour vinegar or homemade citric acid mixtures into the tank. A typical visit takes from an hour; a brew unit that needs spare parts is usually back in service within a few days.
