The troubleshooting information in this article is based on general service manuals and may not apply to your specific appliance model.

For the most accurate guidance, we strongly recommend consulting the technical sheet for your specific appliance model.

What is the main control?

The main control board, also called the electronic control board or user interface board, serves several key functions:

• Overall control: The control board is the “brain” of the washer, responsible for monitoring and controlling all the various cycles, settings, and operations of the machine.
• User interface: The control board interfaces with the user controls, such as the cycle selection knob, buttons, and display. It interprets the user’s inputs and adjusts the washer’s behavior accordingly.
• Cycle sequencing: It manages the sequencing and timing of the various wash cycle steps, like filling the tub with water, agitating, draining, spinning, etc.
• Motor control: It controls the operation of the washer’s electric motor, which powers the agitator and spin basket.
• Water level sensing: It monitors the water level in the tub and adjusts the fill cycle accordingly.
• Temperature regulation: It regulates the water temperature by controlling the heating element or water inlet valves.
• Safety interlocks: The control board monitors safety features like the door lock and will not allow the washer to operate if a safety issue is detected.

If the control board fails or is not receiving power, the washer will be unable to power on or function properly. Replacing a faulty control board is often necessary to restore full operation of the appliance.

Tools and materials

• Multimeter
• Putty knife
• 1/4 inch nut driver

The specific tools required may vary depending on the model of your appliance and the type of fasteners used on it. Always consult the user manual or refer to any specific instructions provided by the manufacturer for the recommended tools for your appliance model.

Safety precautions

When working on any appliance, remember to keep safety first. Here are some tips to keep in mind: 

• Always power off and unplug your appliance or switch off the circuit breaker before attempting any maintenance or replacement work. This keeps you safe by preventing any risk of injury from electric shock.
• Wear insulated work gloves to protect your hands from sharp metal parts, pinching hazards and debris.
• Take your time and don’t rush while working to prevent accidents and personal injuries.
• Work in a well-lit area so you can clearly see and access the interior parts.
• Clear your workspace of clutter and other obstacles. Keep children and pets away from the work area.
• Never work on internal parts with bare wet hands. Make sure the work area is completely dry.
• Check your user manual to see if there are specific installation or safety instructions for your part or appliance. 
• Be gentle when handling or removing parts. Excessive force might damage the appliance or cause injury.
• Wear safety glasses when working with chemicals, dust or cleaning large debris to prevent injury. 
• If the appliance has recently been used, give it plenty of time for any heating parts to cool down before working on it. 
• Take pictures or make a note of wiring terminals or other connections before disconnecting to prevent any problems with reassembly.
• When working with wires, avoid touching any exposed wires or terminals. If you need to touch a wire, use a non-conductive tool or wear insulating gloves to prevent electrical shock.

Testing steps

LIVE VOLTAGE WARNING: For this test, the appliance needs to be plugged in and powered on. Please be very careful to protect yourself from electric shock, which has the potential to cause serious injuries. Don’t ever test live voltage if you’re uncomfortable using a multimeter.

1. Unplug the power cord from the electrical outlet.
2. Using a 1/4-inch nut driver, remove the screws securing the rear console cover. Set the cover aside.
3. Use a putty knife to press into the lock tabs at the bottom front corners of the console.
4. With the tabs pressed in, lift the front of the console up and slide it forward.
5. Set the console on its face.
6. Plug the power cord back in to power on the washer.
7. Set your multimeter to Volts AC (V~).
8. Test the voltage at the control connection J7, where the power cord is connected.
9. If you see 120V AC, the main control has failed and needs to be replaced.
10. If there is no 120V AC, there may be a problem with the power cord or power supply.
