Possible Causes
Blocked pump or hose, Faulty drain pump, Pressure switch not resetting to empty, Wiring fault between pump and PCB
How to Fix / Troubleshooting
Safety first: Unplug the washer and prepare for water spillage.
Step-by-step checks:
- Repeat drain checks: Clean the pump filter, inspect the drain hose, and verify the standpipe is not blocked.
- Check pressure switch empty state: With the drum empty, test the pressure switch to ensure it indicates 'empty'. A stuck switch can prevent spin and trigger E20.
- Test pump electrically: Measure pump coil resistance and check for supply voltage during drain. Replace the pump if it does not run when powered.
- Inspect wiring: Follow the pump wiring to the PCB, repairing any damage.
