LG Washer tCL: Tub Clean Reminder (Not an Error)

The tCL code on LG washers is a maintenance reminder, not an error. Your washer is working perfectly—it’s just telling you it’s time to clean the tub to prevent odor and residue buildup.

Why tCL Appears

LG washers track the number of wash cycles and display tCL after approximately 30 cycles to remind you to run maintenance. This counter-based reminder ensures regular cleaning.

Why cleaning matters:

• Detergent residue builds up on the drum and gasket
• Fabric softener leaves a film that can harbor bacteria
• Front load washers retain moisture in the gasket folds
• Residue + moisture = mold and mildew odors

How to Run Tub Clean Cycle

Step 1: Empty the Washer

Remove all clothing and items from the drum. The tub clean cycle must run with an empty drum.

Step 2: Add Cleaning Agent (Optional but Recommended)

Option A: Washer Cleaning Tablets

• Place one tablet directly in the drum (not the dispenser)
• Use LG-branded tablets or any washer cleaning tablet
• Brands: Affresh, Tide Washing Machine Cleaner, OxiClean

Option B: Liquid Chlorine Bleach

• Add 1/2 cup liquid chlorine bleach to the bleach dispenser
• Do NOT use splash-less or scented bleach

Option C: No Cleaning Agent

• The cycle still helps by using hot water and extended agitation
• Less effective for heavy residue or odor problems

Step 3: Select TUB CLEAN

1. Turn on the washer
2. Rotate the cycle selector to TUB CLEAN
3. This cycle is available on all LG washers

Step 4: Start the Cycle

Press Start. The cycle runs for approximately 60-90 minutes depending on your model.

What the cycle does:

• Fills with hot water
• Agitates at high speed
• Soaks for extended periods
• Drains and rinses multiple times
• Spins to remove water

Step 5: Post-Cycle Maintenance

After the cycle completes:

1. Wipe the door gasket — Clean all folds with a dry cloth
2. Wipe the door glass — Inside and outside
3. Leave the door open — Allows the drum to air dry
4. Remove the dispenser drawer — Rinse and dry if needed

How to Dismiss tCL Temporarily

If you can’t run tub clean right now, you can dismiss the reminder:

1. Press any button to clear the display
2. The washer will operate normally
3. tCL will return on the next power cycle until you run the cleaning cycle

Preventing Odors Between Cleanings

For Front Load Washers

1. Wipe the gasket after each use — Remove moisture from folds
2. Leave the door ajar — Allow air circulation
3. Use HE detergent — Regular detergent causes excess suds and residue
4. Don’t overdose detergent — More isn’t better
5. Run hot water cycles periodically — Cold water doesn’t dissolve residue as well

For Top Load Washers

1. Leave the lid open — Between loads and overnight
2. Use appropriate detergent amounts — Follow package directions
3. Run tub clean monthly — Even if tCL hasn’t appeared

Model Coverage

The tCL reminder appears on all LG washers:

Front Load (WM series): All models with digital displays

Top Load (WT series): All models with digital displays

Frequently Asked Questions

Can I run a regular cycle instead of tub clean?

No. Regular cycles don’t use the specific water levels, temperatures, and agitation patterns needed for effective cleaning. The TUB CLEAN cycle is specifically designed for this purpose.

Is tCL the same as an error code?

No. Error codes indicate problems that stop the washer from operating. tCL is an informational reminder — your washer will continue to work normally even if you ignore it (though you shouldn’t).

What if my washer smells even after running tub clean?

If odors persist:

1. Run tub clean 2-3 times in a row with cleaning tablets
2. Clean the drain pump filter (front loaders only)
3. Check the detergent dispenser for buildup
4. Ensure you’re using HE detergent
5. Consider professional cleaning if severe
