TCL on LG Washer: Tub Clean Cycle Reminder (Not an Error)
Quick Answer
TCL is not a malfunction. Your washer is working fine - it is just asking you to clean the tub. Run the Tub Clean cycle (usually its own setting on the dial or button panel) with a tub cleaner tablet or a cup of white vinegar.

What Does the TCL Code Mean?
LG washers track the number of wash cycles completed in firmware. Every 30 cycles, the control board sets a maintenance reminder flag and displays TCL. This is purely informational - the washer will continue to run normal cycles even if you ignore TCL. However, ignoring it long enough causes the escalated version (ECL) to appear.
Most Likely Causes
Based on aggregated repair data, here is the probability breakdown for this error code:
Symptoms You May Notice
- TCL displayed on screen

Can you reset a Lg washer to clear the TCL code?

Run the Tub Clean cycle
Make sure the drum is empty. Turn the cycle selector to Tub Clean (it has its own position on most LG models) or press the Tub Clean button if your model has one. Add a tub cleaner product (Affresh, LG Tub & Drum Cleaner, or a cup of white vinegar directly into the drum). Press Start. The cycle runs for 60-90 minutes and uses hot water. Do not add any laundry.
Manually clear TCL if it persists after cleaning
