What is the Tub Clean cycle used for?
This maintenance cycle cleans the empty washer rather than clothing.
It uses a dedicated tub-cleaning sequence to reach areas that an ordinary load may not clean. Run it empty and use only the cleaner specified by the manufacturer.
Choose another cycle for: Running with clothing or mixing cleaning products.
What this means for your load
Maintenance program that must be run empty. Check the appliance display for its current estimate.
Why the time may change: Follow the exact cleaner and option instructions in the manual for the documented result.
Check the full LG WT7400CW cycle table to compare other programs before starting.
When will it finish?
This variable program depends on the stored cycle, options or sensed load. Use the appliance's current displayed estimate.
Estimated energy and local cost
This range is calculated from the documented cycle characteristics and appliance type. It is deliberately shown as a range because load conditions, temperature selections, sensors and options change consumption.
