What this code means
The dishwasher leak sensor detected water in the base area. The drain pump may run continuously as a protective response.
Most likely causes
- An inlet, drain, sump, tub or pump connection is leaking
- Excess foam from hand dish soap or too much detergent
- Water entered the base during installation or from a nearby sink leak
- The leak sensor or wiring is contaminated or faulty
Safe checks for the owner
- Turn off power and the dishwasher water supply.
- Inspect the cabinet and floor for active leaking without tipping the dishwasher.
- Do not repeatedly reset the code until the source of water is found.
Estimated U.S. repair cost
