We've had a new LG 2455 washing machine
Not a complete model#.
The owner's manual says to press and hold the EXTRA RINSE button for 3 seconds to activate the TUB CLEAN cycle. (The TUB CLEAN is on the same button as EXTRA RINSE). The display is supposed to show a message to add liquid bleach to the dispenser. When I press the EXTRA RINSE button for 3 seconds, the CHILD LOCK button (another one of several special function buttons) lights up, then nothing happens.
Similier to one model I picked...
A buildup of detergent residue can occur in the wash tub over time and can lead to a mildewy or musty smell. The TUB CLEAN cycle is specially designed to remove this buildup. Press and hold the EXTRA RINSE button for 3 seconds to activate this cycle. The display will show a message to add liquid bleach to the dispenser. After the cycle has ended, open the door and allow the drum interior to dry completely.
NOTE: Do NOT use this cycle with clothes, and do NOT add detergent or fabric softener.
Use this option to prevent unwanted use of the washer or to keep cycle settings from being changed while the washer is operating. Press and hold the
PREWASH button for 3 seconds to activate or deactivate CHILD LOCK.
The lock icon will be shown in the display, and all controls are disabled. The washer can be locked during a cycle. Once CHILD LOCK is selected, the
display will alternate between CL and the time remaining.
before calling the LG service number
Probably a good idea.
