Safety: Unplug the machine before accessing the pump or control board.

Listen for pump: When starting a brew cycle, if you hear no pump noise at all, suspect electrical or control issues. A humming noise with no water flow suggests a seized pump.
Check wiring: Access the pump compartment. Verify that the pump connectors are firmly attached and that wires are not burnt or broken.
Test pump directly: If you are qualified, briefly power the pump with an appropriate test cord (with the pump removed from the machine) to confirm it runs. If it does not, replace the pump.
Inspect control board: Look for burnt components near the pump triac/relay. If damaged, replace the control board.
Thermal protector: Some pumps have an internal thermal fuse that opens if overheated. If the pump is open‑circuit on a resistance test, replacement is required.

Warning: Directly powering the pump involves mains voltage and should only be done by trained personnel.

Machine shows E09 and the pump does not run during brew cycles.
