Quick answer
Write down the exact LG dishwasher code before clearing it. Check the model-specific meaning, then perform only the safe check named for that code—such as a filter, hose, water-supply, lock, or door check. Codes that return after the listed correction need service.
Work through in order
Diagnostic checks
Use only checks that match the exact appliance or system and its official guide.
-
Check 1
Record the exact code, photograph the display if useful, and note whether it appears at power-on, fill, wash, drain, or drying.
Expected result: the code is readable and tied to a cycle stage or is unknown
Next step: Use the exact model manual or LG code guide and do not guess a component from the letters alone.
Why this matters
Why: The exact code and timing select the correct branch; an unknown or model-mismatched code cannot be safely interpreted generically.
-
Check 2
For an inlet or water-supply code, check that the household supply is available and the inlet hose is not pressed or kinked.
Expected result: water is unavailable, the hose is kinked, or both are normal
Next step: Open only an accessible shut-off valve as instructed; request service if the code returns.
Why this matters
Why: A supply interruption or restricted hose can prevent filling; normal supply makes a sensor or valve fault more likely.
-
Check 3
For an OE or drain-related code, clean and reseat the filter after the tub cools and inspect the accessible drain hose for a bend.
Expected result: water drains after the check or remains above the filter
Next step: Do not reach into hot water or dismantle the pump; request service for continuing pooling.
Why this matters
Why: LG links OE to incomplete drainage, residue in the filter, or a pressed drain hose; persistent water needs inspection.
-
Check 4
For CL, door, temperature, heater, motor, or other persistent codes, follow only the model-specific user step and retry once.
Expected result: the code clears or immediately returns
Next step: Stop repeated cycles and provide the code and model to a qualified technician.
Why this matters
Why: A cleared code may have been a transient state; recurrence indicates the underlying condition remains.

Decision map
Find the observation that best matches what you see, then follow the next safe action.
-
PATH 01Next step
What you see
The code maps to a kinked hose, dirty filter, or control lock and the condition is visibly present
Do this next
Correct that condition, then retry once.
-
PATH 02Next step
What you see
The code is unknown, returns after correction, or concerns heater, motor, sensor, or wiring
Do this next
Stop repeated operation and request service.
Helpful context
Understand the symptom
The code is the identity of the problem
Do not diagnose from a generic 'error' label. Record letters and capitalization, note when it appears, and compare it with the exact model's guide because LG says codes can differ by model.
Only after diagnosis
Potential parts
- dishwasher filter
Only consider a filter replacement if the exact model guide identifies a damaged filter after cleaning and reseating.
Confirm the complete model before ordering; codes involving heaters, motors, or wiring require professional diagnosis.
When checks do not resolve it
Need a professional?
Stop for smoke, burning odor, leaking water, repeated breaker trips, exposed wiring, hot standing water, or any code that returns after its documented user check. Request qualified service.
Common questions
FAQ
Can I clear an LG dishwasher error by turning it off?
A reset may clear a transient state, but the correct action depends on the exact code and model. If the code returns, use the documented service path rather than repeating resets.
Why does the same code mean different things on different LG dishwashers?
LG notes that error and notification codes can differ by model. Record the complete model number with the code before choosing a repair step.
