Possible Causes
Water in base pan triggering float, Stuck float switch, Leaking hose or pump, Oversudsing from wrong detergent
How to Fix / Troubleshooting
Safety First: Disconnect power and turn off water supply.
Steps:
- Check for leaks: Remove the toe kick panel and inspect the base pan for standing water. If present, carefully sponge or vacuum it out.
- Inspect float switch: Locate the float switch in the base. Ensure it moves freely and is not stuck in the up position. Check its wiring.
- Run a test cycle: After drying the base, restore power and run a short cycle while observing underneath for drips from hoses, pump, or door seal.
- Correct detergent use: If you see excessive suds inside, run a rinse cycle with a small amount of cooking oil or a defoamer and switch to proper dishwasher detergent.
- Repair leaks: Tighten hose clamps, replace cracked hoses, or replace leaking pump seals as needed.
