What LC means
The leak sensor has detected moisture. The dishwasher will try to drain and may not turn off until the moisture is gone. On Waterwall models it can also mean the water reflector is blocked.
Also shown as: LE, depending on the model.
Likely causes
- A leak at the supply or drain hose
- Too much or the wrong detergent causing suds
- Disposal cap left in place
Safe first checks
- Turn the dishwasher off at the breaker, wipe up any water and look for a leak along the supply hose and its connections.
- Check you're using the right amount of automatic-dishwasher detergent, and on Waterwall models make sure nothing is blocking the reflector.
- Let it dry out for a while, then restore power and see if the code returns.
When to stop
If the code comes back, request service.
