How to Fix / Troubleshooting
Safety first: Disconnect power and turn off water. Be prepared for water when tilting the unit.
- Check base pan: Remove the kick plate and inspect the base pan for water. If present, carefully tilt the dishwasher to drain into a shallow container or towels.
- Inspect float switch: Locate the anti-flood float switch and ensure it moves freely. Test with a multimeter; replace if stuck or shorted.
- Find and fix leak: Run a short fill cycle while observing the underside for leaks from the inlet valve, sump gasket, circulation pump, or hoses. Tighten clamps and replace any cracked components.
- Dry thoroughly: Use a fan or allow time for the base area to dry completely before reassembly.
- Test operation: Restore power and run a full cycle to confirm E15 is cleared and no further leaks occur.
