Is their a self clean on thus model?

Hi there, Joe. Thank you for sharing your inquiry with us. We understand your inquiry about a self-clean feature on your LG WT8400CW washer. This model includes a Tub Clean cycle designed to help you maintain a fresh, odor-free drum. To use the Tub Clean cycle: Empty the Drum: Remove all laundry and visible items from inside the washer. Add Cleaning Agent: For best results, add a washing machine cleaner or use a small amount of bleach in the bleach compartment as instructed in your user manual. Do not add clothing or detergent. Select Tub Clean: On the control panel, choose the “Tub Clean” cycle. The cycle typically runs around an hour, adjusting time as needed to thoroughly clean the drum. Start the Cycle: Press Start/Pause. When the cycle completes, open the lid and the detergent dispenser area to allow any remaining moisture to evaporate. Regular Maintenance: Run Tub Clean monthly or when you see the reminder (“tcL” indicator) to prevent musty odors and residue build-up. https://www.lowes.com/pd/LG-Top-Load-Washer/5014906269 If you need further guidance on running the Tub Clean cycle, interpreting indicators, or selecting cleaning products, please send us a private message on Social Media @LGUSSupport and our team will be more than happy to explore possible solutions. We appreciate your patience and thank you for choosing LG. —Renzo
