Troubleshooting Made Easy: Learn How To Test Maytag Dishwasher Control Board And Save Money

Maytag dishwashers are renowned for their reliability and efficiency in cleaning dishes. However, like any other appliance, they can experience occasional issues. One of the most common problems is a faulty control board. This blog post will provide you with a comprehensive guide on how to test a Maytag dishwasher control board, helping you diagnose and troubleshoot any issues effectively.

Understanding the Control Board:

The control board is the brain of your Maytag dishwasher. It receives signals from the user interface, such as the buttons and dials, and sends instructions to the various components to perform the desired functions. A faulty control board can lead to various issues, including the dishwasher not starting, not draining properly, or not cleaning the dishes effectively.

Symptoms of a Faulty Control Board:

Here are some common symptoms that may indicate a faulty control board in your Maytag dishwasher:

• The dishwasher does not start when you press the “Start” button.
• The dishwasher starts but does not complete the wash cycle.
• The dishwasher does not drain properly, leaving water in the bottom of the tub.
• The dishwasher does not clean the dishes effectively, leaving them dirty or with food residue.
• The dishwasher displays error codes or unusual lights on the control panel.

Testing the Control Board:

To test the control board, you will need a multimeter and a basic understanding of electrical circuits. Here are the steps involved:

1. Disconnect the Power:

Before you begin testing, ensure that the dishwasher is disconnected from the power source. This can be done by unplugging it or turning off the circuit breaker that supplies power to the dishwasher.

2. Locate the Control Board:

The control board is typically located inside the dishwasher door, behind the control panel. To access it, you may need to remove a few screws or clips that hold the control panel in place.

3. Inspect the Control Board:

Once you have accessed the control board, inspect it for any visible signs of damage, such as burnt components, loose wires, or corrosion. If you notice any abnormalities, it is likely that the control board is faulty and needs to be replaced.

4. Test the Power Supply:

Using a multimeter, check the power supply to the control board. Ensure that the voltage matches the specifications provided in the dishwasher’s user manual. If the voltage is incorrect or inconsistent, it could indicate a problem with the power supply or the wiring.

5. Test the Control Board Components:

Use the multimeter to test the individual components on the control board, such as relays, capacitors, and transistors. Refer to the dishwasher’s technical manual or schematics to identify the specific components and their expected values. If any component shows abnormal readings or is not functioning correctly, it is likely faulty and needs to be replaced.

6. Test the User Interface:

Test the user interface buttons and dials to ensure they are sending signals to the control board correctly. You can do this by pressing each button or turning each dial while observing the corresponding LED indicators or display lights. If any button or dial does not register a signal, it could be faulty and needs to be replaced.

Conclusion:

By following the steps outlined in this blog post, you can effectively test the control board of your Maytag dishwasher and diagnose any issues. If you find that the control board is faulty, it is recommended to replace it with a new one to restore the dishwasher’s functionality. Always remember to take necessary safety precautions and consult a qualified appliance repair technician if you are unsure about any part of the testing process.
