What the Service Includes
The service for repairing a coffee machine with water leaking from the bottom or drip tray includes comprehensive hydraulic system inspection and elimination of all detected causes. Main operations:
- precise localization and cause identification of the leak (external inspection + disassembly)
- checking all seals, gaskets, O-rings in the hydraulic system
- inspection and testing of the drain valve (dump / relief valve)
- testing boiler, tubes, fittings and connections for tightness
- diagnostics of the brew group (seals, piston, shower screen)
- checking crema valve (OPV), steam valve, safety valve
- inspection of tubes — especially teflon and silicone — for kinks and cracks
- replacement of worn gaskets, seals, O-rings, siphon seals
- replacement of the drain valve if it does not hold pressure or fails to close
- repair or replacement of leaking boiler nodes (inlet/outlet, sensor)
- replacement of cracked or swollen tubes and fittings
- flushing the hydraulic system from scale and coffee oils
- full testing after repair: multiple brew and steam cycles, drip tray dryness check
- pressure and standby mode leak verification
Service is performed on De’Longhi, Saeco, Philips, Jura, Krups, Siemens, Bosch, Melitta, Nivona, Gaggia and other brands.
When This Service Is Needed
Main signs indicating the need for leak repair:
- water drips or flows from the bottom of the machine even when turned off
- drip tray fills very quickly during use or stays full without operation
- water appears under the machine after every brew or after idle time
- leakage from under the button panel, display or sides of the body
- during brewing water flows not only through the group but also from underneath
- machine shows errors “leak detected”, “aqua stop”, “drain valve”
- constant water dumping into the tray even without pressing buttons
- coffee comes out watery and drip tray overflows after brewing
- sound of dripping water inside the machine or visible puddle underneath
- problem worsened after self-cleaning or water change
Most frequent causes: worn brew group seals, faulty drain valve, cracked tubes, deformed boiler gaskets, crema valve failure, scale in connections.
