Before starting
Use only the instructions supplied for your exact model. If there is a leak, smoke, hot wiring or gas smell, stop and seek qualified help.
1. Open safely
Stop the cycle and allow hot water to cool. Keep towels ready; do not run a leaking machine.
2. Clean the lower filter
Remove the lower rack and clean only the model-approved filter. Reinstall securely; do not force open the pump cover.
3. Check the external drain
Look for sink backup and sharp hose kinks. Do not pull built-in machines out without support; follow the installation instructions.
4. Interpret the result
If safe, run your model’s cancel/drain function once. Persistent standing water or grinding requires service.
