Exact questions
Common questions about “LG washer tcL code”
What does tcL mean on a LG washer?+
It means the washer is reminding you to run the Tub Clean cycle.
Can I clear tcL by resetting the washer?+
A restart may clear a stored display only after the underlying condition is corrected. Repeatedly resetting without correcting the cause is not a repair.
Where do I find the Tub Clean cycle?+
It is a cycle on the dial or in the cycle list, not a separate button. Select Tub Clean, add the cleaner where your manual says (the drum or the dispenser, depending on the model), and start it with the drum empty.
How do I clear the reminder?+
Run Tub Clean with the drum empty. The reminder resets when the cycle completes.
How often does the reminder appear?+
It appears after a set number of cycles, commonly every 30 washes on LG models, though the exact number depends on the model. It is a timer, not a sensor reading.
What if the drum smells even after Tub Clean?+
Leave the door and dispenser drawer ajar between loads, wipe the door gasket, and use the correct amount of detergent for high-efficiency machines. Persistent odor may mean residue deeper in the tub.
Do I need special cleaner for Tub Clean?+
LG recommends running the cycle empty, and many owners add a washer cleaner tablet or a small amount of bleach as the manual for the model allows. Follow the manual for your model and do not mix cleaners.
Can I ignore the reminder?+
You can, and the washer will keep working, but the tub can build up detergent residue and odor over time. Running the cycle when the reminder appears keeps the drum fresher.
How often should I run the Tub Clean cycle on an LG washer?+
LG recommends running it about once a month, or when the TCL light comes on, with the drum empty and a washer cleaner if you use one.
Can I run the Tub Clean cycle with clothes in the drum?+
No. Run it empty, and leave the door ajar afterwards so the drum and gasket can dry.
