  1. Verify the exact code and model

    Reversible

    Photograph the complete display and model label. Code aliases in this record: tcL, tCL. LG front-load washers and washer-dryer combos. LG publishes a separate error-code list for top-load washers; codes such as Ed1–Ed5, dcL and OPn apply only to models with the ezDispense liquid dispenser.

  2. Perform the first non-destructive check

    Reversible

    Empty the tub completely. Do not clear the display before recording the operating stage and remaining water, heat or load state.

  3. Correct only the documented fault domain

    Reversible

    Add powder washing machine cleaner, select Tub Clean on the knob or press the Tub Clean button, and start the cycle. LG notes the message may keep appearing for a few cycles. Do not substitute a similar brand or product code table for the exact model manual.

  4. Verify or escalate

    Reversible

    Run only a safe short test that reaches the original stage. If tcL, tCL returns, stop repeated resets and use model-specific manufacturer service.
