How to Fix Error LOC — Step by Step

1

Step 1: Check the Control Lock Button

Locate the control lock button on the Whirlpool Washing Machine's control panel. Check if the button is pressed and held. If it is, release the button and see if the washer starts. If the washer still doesn't start, proceed to the next step.

💡 Pro Tip: Make sure to check the control lock button carefully, as it's easy to overlook.

Step 2: Reset the Control Panel

Press and hold the 'Cancel' button for 3 seconds to reset the control panel. This will clear any stored error codes, including the LOC error. Release the 'Cancel' button and see if the washer starts.

💡 Pro Tip: Resetting the control panel can resolve the LOC error in many cases.

Step 3: Check the Control Lock Circuit

Use a multimeter to test the control lock circuit. Set the multimeter to the ohms function and measure the resistance between the control lock button and the control panel. If the resistance is within the specified range (usually 1-5 kΩ), the circuit is functioning correctly.

💡 Pro Tip: Make sure to consult the Whirlpool Washing Machine's user manual for the correct resistance range for the control lock circuit.

Step 4: Replace the Control Lock Button

If the control lock circuit is functioning correctly, but the LOC error persists, it's likely that the control lock button is faulty. Remove the control panel using a Torx T20 screwdriver and locate the control lock button. Replace the button with a new one, making sure to secure it properly with the Torx T20 screwdriver.

💡 Pro Tip: Make sure to purchase a genuine Whirlpool control lock button to ensure compatibility and proper function.

If a fault is detected, consult the Whirlpool Washing Machine's user manual for instructions on how to repair or replace the wiring.

💡 Pro Tip: Make sure to consult a professional if you're not comfortable with electrical repairs.

What Does Whirlpool Washing Machine Error Code LOC Mean?

The LOC error pops up on a Whirlpool washer when the control lock is turned on. Think of the control lock as a safety latch that stops the machine from starting or continuing a cycle. When it’s engaged, the washer’s buttons and dial become unresponsive, and the display will show the LOC code. This usually happens if someone presses the lock button for too long or if the lock mechanism malfunctions. The machine will stay in this state until the lock is disabled, so you’ll see the error every time you try to start a wash.

Seeing LOC on the display can be frustrating because the washer looks fine but won’t run. The lock is a built‑in feature to prevent accidental use, especially in households with children or pets. Once the lock is off, the washer should resume normal operation.

Common Causes of Error LOC

Button Held Too Long – The lock button is designed to activate after a few seconds of being pressed. If the button is held for 10‑15 seconds, the lock stays on.
Faulty Lock Button – Wear and tear can cause the button’s internal contacts to stick, keeping the lock engaged even after you release it.
Control Panel Malfunction – A glitch in the electronic control board can falsely trigger the lock mode.
Wiring Issues – Loose or damaged wiring between the lock button and the control board can send a continuous “lock” signal.
Power Surges – A sudden spike in voltage can reset the control board into lock mode as a safety measure.
User Error – Accidentally pressing the lock button while the washer is running or during a cycle can lock the machine mid‑cycle.

How to Prevent Error LOC

Use the Lock Button Correctly – Press it only when you need to lock the controls, and release it within 5 seconds.
Check the Button Regularly – Inspect the lock button for signs of wear, such as a sticky feel or visible cracks. Replace it if it looks damaged.
Keep the Control Panel Clean – Dust and grime can interfere with button contacts. Wipe the panel with a dry cloth every few months.
Avoid Power Surges – Plug the washer into a surge protector or use a voltage stabilizer to protect the control board.
Perform a Quick Reset – If you see LOC, press and hold the Cancel button for 3 seconds to reset the panel. This can clear temporary glitches.
