Whirlpool Washer LOC Error Code: Control Lock

Quick Answer

LOC means the Control Lock feature has been enabled, intentionally or accidentally. When active, the control panel does not respond to button presses, which can be alarming if it was activated unknowingly. On most models, pressing and holding the Control Lock button (or the button labeled with a padlock icon) for 3 seconds will toggle the lock off.

LOC means the Control Lock feature has been enabled, intentionally or accidentally. When active, the control panel does not respond to button presses, which can be alarming if it was activated unknowingly. On most models, pressing and holding the Control Lock button (or the button labeled with a padlock icon) for 3 seconds will toggle the lock off. On Cabrio and Duet models, holding the Cycle Signal button for 3 seconds performs the same function. LOC is not a fault, and the machine is in perfect working order once the lock is deactivated.

Follow these steps in order. We start with the easiest external fixes before opening up the machine.

Locate the button on the control panel labeled Control Lock

Frequently Asked Questions

Why does my Whirlpool washer keep activating LOC on its own?
LOC is only activated by holding a specific button for 3 seconds. If it activates repeatedly without your input, the button may be physically sticking or the control panel may have a developing fault. Clean around the button with a dry cloth and monitor.
Is LOC different from the machine being off or unresponsive?
Yes. When LOC is active, the display still shows LOC and the machine has power. If the display is completely dark and the machine does not respond to the power button, that is a different issue involving power supply rather than the control lock feature.
