Before starting
Use only the instructions supplied for your exact model. If there is a leak, smoke, hot wiring or gas smell, stop and seek qualified help.
1. CL can indicate control lock
On many LG dishwashers, CL indicates control lock, not a failed part. Check the model-specific unlock method.
2. PF may indicate a power interruption
LG dishwashers can show PF after interrupted power. Resume only if the supply is stable; recurring trips need an electrician.
3. Cleaning reminders
Some washers display tCL for tub cleaning; some ACs display CF for filter maintenance. Verify your model.
4. If it is a real fault
Record the exact display, model, stage and symptoms. Do not authorize expensive part replacement based on a generic internet code alone.
