What Does Error Code CL Mean?

When your Lg dishwasher displays CL, it means heating element failure. Check the motor first, as it's the most common culprit.

Diagnostic Check	Expected Result	If Failed
Check water supply valves (hot & cold)	Both valves fully open, good water pressure	Open valves, check for kinks in hoses
Inspect drain hose for clogs	Clear path, hose not kinked or clogged	Clear blockage, straighten hose
Test door/lid switch with multimeter	Continuity when closed, no continuity when open	Replace door/lid switch assembly
Check load balance	Load evenly distributed in drum	Redistribute clothes, run spin cycle
Verify drain pump operation	Pump runs, water drains within 2 minutes	Clean pump filter, check for obstructions

Load Size Rule: Never fill the drum more than 3/4 full. Overloading is the #1 cause of unbalance errors and premature bearing failure.
