Quick answer
Separate a blank panel, locked controls, a door that will not latch, and a cycle that stops. Check power and Control Lock, close the door fully, and verify the water supply. Stop and arrange service for leaks, repeated breaker trips, or a persistent fault.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Press Power and note whether the panel is blank, shows CL, shows a code, or responds normally.
Expected result: The panel is blank, locked, coded, or responsive.
Next step: Check breaker when blank and disable Control Lock using the model procedure when CL appears.
Why this matters
Why: Blank points to power; CL means Control Lock; a code needs model guidance; response allows door/water checks.
-
Check 2
Check the breaker and power connection, resetting the breaker once if safe.
Expected result: The panel returns or stays blank / the breaker trips again.
Next step: Leave it off and request qualified service.
Why this matters
Why: A repeat trip is an electrical fault.
-
Check 3
Close the door firmly, check the latch for an obvious obstruction, and verify the inlet valve is open and hose not kinked.
Expected result: The cycle starts or remains unable to start.
Next step: Correct only an obvious obstruction/kink and request service for latch, valve, or hose work.
Why this matters
Why: A door or water-supply condition can prevent a cycle; persistent failure needs diagnosis.

Helpful context
Understand the symptom
Define the failure
LG dishwashers can appear inactive because Control Lock is on, a cycle is being canceled, or the panel is not receiving power. The exact symptom changes the next check.
When checks do not resolve it
Need a professional?
Call for leak, repeat breaker trip, damaged cord, failed latch, persistent code, or no operation with confirmed power.
