Control Board Conundrum? Master The Art Of Testing Maytag Dishwasher Control Boards

A malfunctioning control board can disrupt the smooth operation of your Maytag dishwasher, leaving you with a pile of dirty dishes and a headache. To diagnose and fix the issue effectively, it’s crucial to know how to test Maytag dishwasher control boards. This detailed guide will provide you with step-by-step instructions to help you identify and troubleshoot control board problems.

Understanding the Maytag Dishwasher Control Board

The control board is the central processing unit of your Maytag dishwasher. It manages all the electrical functions, from controlling the water flow to operating the wash cycles. If the control board fails, the dishwasher may not respond, display error codes, or malfunction in various ways.

Tools and Safety Precautions

Before you begin testing the control board, gather the following tools:

• Multimeter
• Screwdriver
• Wire strippers
• Electrical tape
• Safety glasses

Always wear safety glasses when working with electrical components. Disconnect the dishwasher from the power supply before performing any tests.

Step-by-Step Testing Procedure

1. Visual Inspection

Examine the control board for any visible damage, such as burnt components, broken wires, or loose connections. If you notice any irregularities, take a picture or make a note for further troubleshooting.

2. Power Supply Check

Using a multimeter, set it to the AC voltage setting. Connect the black lead to the neutral wire and the red lead to the hot wire. The voltage should be around 120 volts. If there’s no voltage, check the circuit breaker or fuse.

3. Ground Test

Set the multimeter to the continuity setting. Connect the black lead to the ground wire and the red lead to the chassis of the dishwasher. There should be continuity, indicating a proper ground connection.

4. Keypad Test

Disconnect the keypad connector from the control board. Set the multimeter to the continuity setting. Touch the black lead to one of the terminals on the keypad connector and the red lead to the corresponding terminal on the control board. When you press a key on the keypad, there should be continuity between the terminals. Repeat this process for all keypad buttons.

5. Motor Control Test

Disconnect the motor connector from the control board. Set the multimeter to the continuity setting. Connect the black lead to one of the terminals on the motor connector and the red lead to the corresponding terminal on the control board. When you select a wash cycle, there should be continuity between the terminals, indicating that the control board is sending power to the motor.

6. Drain Pump Test

Disconnect the drain pump connector from the control board. Set the multimeter to the continuity setting. Connect the black lead to one of the terminals on the drain pump connector and the red lead to the corresponding terminal on the control board. When you select the drain cycle, there should be continuity between the terminals, indicating that the control board is sending power to the drain pump.

7. Water Valve Test

Disconnect the water valve connector from the control board. Set the multimeter to the continuity setting. Connect the black lead to one of the terminals on the water valve connector and the red lead to the corresponding terminal on the control board. When you select the fill cycle, there should be continuity between the terminals, indicating that the control board is sending power to the water valve.

Troubleshooting Common Issues

• Dishwasher not responding: Check the power supply, ground connection, and keypad.
• Error codes: Refer to the dishwasher’s user manual for specific error code meanings.
• Dishwasher not filling with water: Test the water valve and the fill sensor.
• Dishwasher not draining: Test the drain pump and the drain hose.
• Dishwasher not washing dishes: Test the motor, the water temperature sensor, and the detergent dispenser.

Replacing the Control Board

If all tests fail, it’s likely that the control board needs to be replaced. Contact an authorized Maytag repair technician or purchase a new control board online.

Tips for Prevention

• Regularly clean the dishwasher’s filter and spray arms to prevent food particles from clogging the system.
• Use the correct amount of detergent and rinse aid.
• Avoid overloading the dishwasher.
• Run the dishwasher on a hot water cycle once a month to remove any mineral buildup.
