LG Washing Machine (Wash Tower) tCL error code

Difficulty: Easy · Cost: $5–$15 · Duration: 45–90m

tCL on your LG WashTower washer is a reminder to run the Tub Clean (Tub Sterilization) cycle to remove microorganisms and residue from inside the drum. Use an oxygen-based washing machine cleaner — avoid chlorine-based or acidic cleaners. The dryer section of the WashTower does not have a Tub Clean reminder. LG recommends running the Tub Clean cycle at least once a month.

Common causes

  5. 5
