What tCL (Tub Clean Reminder) Means
tCL is a maintenance reminder, not a fault, on both LG front-load and top-load washers - it means it's time to run the Tub Clean cycle to keep the drum free of buildup and odor-causing residue. LG's SideKick pedestal-washer article notes the same reminder appears there automatically every 30 cycles.
Common Causes of tCL (Tub Clean Reminder)
- Regular cycle count has reached the point LG's software schedules a Tub Clean reminder
- Washer installed in a humid space or used infrequently, encouraging odor-causing buildup
🔧 One Safe Check You Can Try
Run the Tub Clean cycle empty (no laundry) with the recommended washing-machine cleaner - never detergent or fabric softener, which can create excess suds and weaken the cleaning effect - and the reminder should clear once the cycle finishes; leaving the door open between loads to let the drum dry out also helps prevent it from reappearing too often.
⚠ Why You Shouldn't Go Further Than That
- There's no repair needed - tCL is a scheduled reminder, and skipping it repeatedly (rather than ignoring the display) is what actually risks odor and buildup problems developing.
