How to Replace the Electronic Control Board on a Top-Load Washer

 

file

This step-by-step washer repair guide explains how to replace the electronic control board in the console of a top-load washer. The electronic control board is the "brains" of the washer that starts and stops the washer's components, such as the drive motor and the drain pump. If the control board's display doesn't light up, or if the washer doesn't fill, spin, or drain, the electronic control board could be the problem. Because a problem with the control board can be hard to diagnose, we recommend having a service technician determine the cause. If the electronic control board is faulty, replace it with a manufacturer-approved replacement part.

Instructions

Replacing the Electronic Control Board on a Top-Load Washing Machine

Step 1: Shut off the electricity

Unplug the power cord from the wall outlet.

Step 2: Remove the control knob

Pull the control knob off of the front of the control panel.

Step 3: Open the control console

Pull the washer forward to access the back panel of the console. Remove the 2 screws from the top of the back panel of the console. 

Push back on the control panel while sliding a putty knife under the right corner of the control panel to release the mounting clip. Repeat on the left side to release the console. 

Set the console on top of the washer.

Step 4: Document the wiring connections

Take a digital photograph or otherwise document the location of wires connected to the back of the electronic control board.

Step 5: Disconnect the wires

Release any locking tabs on the wire harness connection plugs and then pull each wire plug out of the connections on the back of the control board.

Step 6: Remove the air hose

Disconnect the air hose from the back of the control board. 

 Tip: The other end of the air hose attaches to the bottom of the washer tub. The hose enables the control board to detect the water level.

Step 7: Remove the electronic control board

Remove the mounting screw from the electronic control board. Release the locking tabs and pull the electronic control board out of the console.

Step 8: Install the new control board

Position the new control board in place and snap it into the locking tabs. Insert the mounting screw in the control board housing and tighten it firmly. 

Step 9: Reconnect the air hose

Reconnect the air hose down to the back of the control board.

Step 10: Reconnect the wires

Using your photograph or other documentation as a guide, connect all  the wires to the back of the new control board. Push the wire harness plugs into the connections on the control board until the locking tabs snap into place.

Step 11: Reinstall the console

Position the console on top of the top panel and snap the mounting clips into place to secure the console on the top panel.

Reinstall the screws at the top of the back panel on the console. Tighten the screws firmly.

Reinstall the control knob.

Step 12: Restore the electrical power

Plug the washer into the electrical outlet. Return the washer to its original location.

Step 13: Calibrate the washer

With the washer shut off, the basket empty (no water or clothes) and the lid closed, enter the diagnostic mode:

Turn the control dial 1 complete rotation (360 degrees) counterclockwise.

Quickly (within about 6 seconds) turn the control dial 3 clicks clockwise, one click back, and one more click clockwise.

All the green status lights blink when you successfully activate the diagnostic mode. 

If the status lights don’t blink, turn the control dial one complete rotation counter-clockwise to reset the control and then try again, this time turning the knob faster.

In the diagnostic mode, select the Calibration Cycle by turning the control dial 4 clicks clockwise. When the Rinse light turns on, press Start to begin the Calibration Cycle, which runs for 2 to 3 minutes.

When the Calibration Cycle ends, the lid unlocks, and the washer shuts off.
