LG Washing Machine Error tCL: Tub Clean Reminder

Clear meaning, realistic next steps, and safe guidance without turning the page into a long repair manual.

What it means

The washer is reminding you to run a Tub Clean cycle to remove detergent residue, mold, and mildew buildup from inside the drum. This is a maintenance reminder, not a fault — the washer will continue to operate normally.

Severity

Low - usually safe to check with basic user-accessible cleaning or inspection on the LG washing machine.

Can you fix it yourself?

Yes — DIY-safe

Most likely cause

The washer has counted 30 wash cycles since the last Tub Clean cycle and is reminding you to clean the drum

Estimated time for safe first checks: 60–90 min (Tub Clean cycle runs automatically).

Step-by-Step DIY Fix Guide

  1. SAFETY: No electrical hazard — tCL is a maintenance reminder.
  2. Ensure the washer drum is completely empty — remove all laundry.
  3. Add a Tub Clean tablet or 1 cup of white vinegar directly to the drum (do not use both).
  4. Select the Tub Clean cycle on the control panel — on most LG models this is labeled 'Tub Clean'.
  5. Start the cycle and allow it to complete fully — it typically takes 60–90 minutes.
  6. After the cycle, wipe the door boot seal with a dry cloth, paying attention to the inner folds where mold typically forms.
  7. Leave the door ajar after the cycle to allow the drum to air dry.
  8. tCL will clear automatically once the Tub Clean cycle is run.

If the airflow problem comes back

  • If airflow still seems weak after the basic checks, the fan path or a deeper obstruction becomes more likely.
  • tCL persists after completing a full Tub Clean cycle — control board may not be registering the cycle correctly
