Error codeLC
ApplianceDishwasher
A leak has been detected
On the current 24-inch Modernist and Heritage dishwashers (DDW24M99* and DDW24T99*), the letters LC stand for leakage check. The dishwasher is telling you it found a leak, and with water and electricity both in play it should be dealt with promptly.
Manual steps in order
Shut off the water supply valve first.
Walk to the house breaker panel and turn this dishwasher’s breaker off.
After the leak is handled, or if LC remains, call (415) 687-5926. Our Dacor dishwasher repair page serves San Francisco and the Bay Area; share the model number and what you have done.
Model compatibility: Dacor reuses codes across series and model years, so LC may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.
Plain language
What this code means
LC is the leakage check, meaning a leak has been detected.
Important safety warning. Do not attempt repairs involving electrical components, gas, water lines, refrigerant or sealed systems. Unplug the appliance if it is safe to reach the outlet, and leave internal diagnostics to a qualified technician.
