Introduction
Go to step 1 ↓If no more coffee comes out, one of the solenoid valves may not be working. To check, you can use the test mode, which will allow you to hear the valves clicking quietly. If you don't hear a click, it is probably defective.
Note: The opening is shown on a different model; there are slight visual differences.
