How to Fix / Troubleshooting
Safety first: Unplug the dishwasher and ensure there is no standing water that could spill when tilting.
- 1. Access drain pump: Remove the lower front panel or tilt the dishwasher to access the base. Locate the drain pump on the sump.
- 2. Check connector: Ensure the electrical connector is firmly attached and free of corrosion.
- 3. Inspect pump body: Look for burn marks, cracks, or signs of overheating.
- 4. Replacement: If the pump does not run at all and E20 is displayed, replace the drain pump with a compatible Finlux unit.
- 5. Test: Reassemble and run a drain program to confirm proper operation.
- 6. Technician help: If a new pump does not fix E20, the control board's pump driver may be faulty and should be checked by a professional.
