LG Washer Error Code tCL (SideKick/Pedestal) — Tub Clean Cycle Reminder
What this means
The tCL code displayed on the LG SideKick pedestal washer (the small secondary washer that sits under the main washer) is a maintenance reminder, not an error. It indicates that a certain number of wash cycles have been completed since the last tub clean, and it is time to run the Tub Clean cycle to prevent odor-causing bacteria and residue buildup. The SideKick's compact tub is particularly prone to residue accumulation because it uses less water. This code can also appear on LG TWINWash systems where the SideKick functions as the bottom washer unit. The tCL reminder will not prevent normal operation — you can still run regular wash cycles — but it is recommended to address it promptly.

Step-by-step fix
3 stepsRun the Tub Clean cycle
Make sure the SideKick pedestal washer is empty. Add a washing machine cleaner tablet or 1/3 cup of liquid chlorine bleach directly into the tub (not the dispenser). Select the Tub Clean cycle and press START.
LG recommends using their branded washing machine cleaner, but any washing machine tub cleaner tablet will work.
Leave the door open after cleaning
After the Tub Clean cycle completes, leave the SideKick drawer slightly open for a few hours to allow the interior to air dry. This prevents moisture from sitting in the sealed tub and causing mold or odors.
Make it a habit to leave the SideKick drawer cracked open after every use, not just after cleaning.
Wipe down the gasket and tub
After the tub clean cycle, use a dry cloth to wipe the door gasket, the inner tub rim, and any visible moisture. Check for any debris or residue that the cycle may not have fully removed.
Pay special attention to the rubber gasket folds where lint, hair, and residue tend to accumulate.
When to call a professional
Not necessary. The tCL code is a routine maintenance reminder. If persistent odor remains after multiple tub clean cycles, a technician can inspect for hidden mold in areas not reached by the cleaning cycle.
