Frequently asked questions
What does tcL mean on a LG washer?
On many model families, tcL indicates that the tub-clean reminder is active. Confirm the exact model and region because the same display can be used differently.
Can I clear tcL by unplugging the washer?
A short power reset may clear a temporary state, but it will not fix a blocked hose, leak, failed sensor, motor, heater, or wiring fault. Stop if the code returns.
Should I replace a part based only on the code?
No. A code identifies a system or condition, not always the failed component. Complete safe external checks and use the model-specific manual or qualified service.
