What Our Customers Say
"I am so happy with the services provided by TruePro Home Services! I have a very old oven that I truly believed would need to be replaced. But, Yury came on time, diagnosed the issues, and had the parts with him to do the repair the same day. My oven is now in perfect working order. Highly recommend!"

"Our LG Front Loading washer wasn't draining. I contacted Simon the next day. He had the part on his truck and came by within 30 minutes, and had it up and running super fast! Thank you Simon for your punctuality, honesty and great value. See you next time!"

"Wonderful and top notched care! They were able to meet my same day expectation to get a washer and dryer hooked up in a new house. He was attentive, thoughtful and explained it all as well. I would highly recommend their service!"

What Error Code tCL Means
The tCL display is a maintenance reminder, not an error code. Your LG washer is telling you to run a Tub Clean cycle. LG washers track the number of wash cycles completed and display tCL after approximately 30 cycles. Residue from detergent, fabric softener, and body oils builds up inside the outer tub and door seal, creating odor and mold. The Tub Clean cycle uses hot water and high spin speeds to flush this buildup.
Common Causes
Regular maintenance interval reached
The washer has completed roughly 30 cycles since the last tub clean. This is the normal trigger for the tCL reminder.
Visible mold or odor
If you also smell mildew or see dark spots in the door seal folds, the tub clean is overdue. The tCL reminder confirms it.
How to Fix It
- 1
Remove all clothes from the drum
The Tub Clean cycle must run with an empty drum. Remove all laundry, towels, and any items from the washer.
- 2
Add a tub cleaning agent
Place a tub cleaning tablet (such as Affresh or LG's own tub cleaner) directly in the empty drum. Alternatively, pour 1/3 cup of liquid chlorine bleach into the detergent dispenser. Do not use both at the same time.
- 3
Select and start the Tub Clean cycle
Turn the cycle selector to Tub Clean. This cycle is labeled on the dial or displayed in the cycle menu. Press Start. The cycle runs for about an hour with hot water, agitation, and a high-speed spin to rinse residue from all interior surfaces.
- 4
Wipe the door seal after the cycle
After Tub Clean finishes, open the door and pull back the folds of the rubber door boot seal. Wipe all surfaces with a dry microfiber cloth. This is where mold and residue hide. Leave the door cracked open to let the interior air dry.
- 5
Prevent future buildup
Use only HE detergent in the recommended amount. Leave the door and detergent dispenser drawer slightly open between loads to let moisture escape. Run Tub Clean monthly or whenever the tCL reminder appears.
When to Call a Professional
The tCL code does not require professional service. If the tCL reminder will not clear after running the Tub Clean cycle, or if your washer has a persistent mold problem that cleaning does not resolve, there is a deeper issue with drainage or the door seal. TruePro can help. Call 877-378-3111 for a $59 diagnostic that gets credited toward any repair. We serve LA County, Orange County, and Ventura County with same-day availability.
Estimated Repair Cost
| Option | Estimated Cost |
|---|---|
| DIY (parts only) | $0 - $8 |
| Professional repair | $90 - $200 |
A tub cleaning tablet costs $3-$8. Bleach costs even less. If a professional service call is needed for persistent odor or a mold-damaged door seal, expect $90-$200 including the $59 diagnostic (which is credited toward the repair).
