Common questions about “Whirlpool washer LoC or LC code”
What does LoC or LC mean on a Whirlpool washer?+
It means Control Lock is enabled rather than a mechanical failure.
Can I clear LoC or LC by resetting the washer?+
A restart may clear a stored display only after the underlying condition is corrected. Repeatedly resetting without correcting the cause is not a repair.
Can I lock the controls on purpose?+
Yes. Control Lock is a feature that stops accidental button presses during a cycle. Turning it on again uses the same button hold, so you can use it whenever you want to keep children or pets from changing settings.
How is LoC different from other codes?+
LoC or LC means the panel is locked, not that anything is broken. Other codes point to a fault that needs a check. If pressing the lock button does nothing, unplug the washer for a minute and try again.
Does Control Lock affect the cycle already running?+
A cycle that has started normally continues. The lock only blocks changes from the panel, so you can leave it on while the washer finishes.
Is LoC or LC a failure code?+
No. It means Control Lock is enabled on the washer, so the panel ignores most button presses. It is a status, not a fault, and it clears when the lock is turned off.
How do I turn Control Lock off?+
Press and hold the Control Lock button, or the button combination shown in the manual for your model, for about three seconds until the LoC display disappears.
What if the code returns straight away?+
Someone may be holding the button, or the panel may be sticking. Unplug the washer for a minute to reset the control, and call service if it keeps locking with nobody touching it.
Where is the Control Lock key on a Whirlpool washer?+
Look for a key marked with a padlock or the words Control Lock; some models need you to hold a combination, such as Cycle Signal, for three seconds. The manual for your model names it.
Why does LoC appear after I clean the panel?+
Wiping the panel while keys are touched can press the lock combination. Switch the washer off, then hold the key again to unlock.
Does Control Lock stop the washer running?+
It stops changes, not a running cycle. Unlock it to start a new cycle or change settings.
