This chapter gives useful hints and information for fault finding. It is not intended as a complete list of possible
errors and malfunctions.
Preventive maintenance plan
When a used coffee module is fitted to a different machine after having been repaired, the following strategy
should be applied:
• Momento 100: Fit a new component if the remaining lifespan is less than 50%.
• Momento 200: Align both coffee modules with the lowest remaining lifespan so both are at the same level.
Components to be replaced periodically
The following are the default lifespans for periodically replaced components:
• Pump: 25'000 cycles → p. 93
• Brewing Unit: 48'000 cycles → p. 97
• Hot water valves: 25'000 cycles → p. 87
• Coffee valves: 25'000 cycles → p. 87
• Drain valve: 48'000 cycles → p. 87
Depending on the customer there might have been different lifespans programmed → p. 29.
