A malfunctioning dishwasher control board can lead to a range of issues, from interrupted wash cycles to complete breakdowns. While replacing the board may seem like the only solution, testing it can often identify the root cause and save you unnecessary expenses. This comprehensive guide will provide you with step-by-step instructions on how to test a Samsung dishwasher control board, empowering you to troubleshoot and resolve the problem effectively.
Safety Precautions
Before embarking on any testing procedures, ensure your safety by following these precautions:
- Unplug the dishwasher from the power outlet.
- Turn off the water supply to the dishwasher.
- Wear protective gloves and eyewear.
Required Tools and Materials
- Multimeter
- Screwdriver set (Phillips and flathead)
- Test leads
- Replacement control board (optional)
Troubleshooting Common Symptoms
Before testing the control board, consider these common symptoms that may indicate a problem:
- Dishwasher won’t start or cycle properly
- Buttons or indicators not responding
- Water not draining from the dishwasher
- Overfilling or underfilling
Step-by-Step Testing Procedure
1. Disconnect the Dishwasher
Unplug the dishwasher and disconnect the water supply hoses. Remove the screws securing the dishwasher to the cabinetry and pull it out slightly.
2. Access the Control Board
Locate the control board, typically situated at the front or back of the dishwasher. Remove the screws holding it in place and carefully disconnect the wiring harnesses.
3. Inspect the Board
Visually inspect the board for any visible damage, such as burn marks, loose components, or broken traces. If any damage is found, it’s likely that the board needs to be replaced.
4. Test the Power Supply
Using a multimeter, set it to the AC voltage setting. Connect one test lead to the neutral wire (white) and the other lead to the hot wire (black). If the multimeter displays a reading of approximately 120 volts, the power supply is functioning correctly.
5. Test the Ground Connection
Switch the multimeter to the resistance setting. Connect one test lead to the ground wire (green) and the other lead to the metal frame of the dishwasher. A reading of close to zero ohms indicates a good ground connection.
6. Test the Buttons and Indicators
Reconnect the wiring harnesses to the control board. Plug in the dishwasher and turn it on. Press each button on the control panel and observe if the corresponding indicators illuminate. If any buttons or indicators fail to respond, it may indicate a faulty control board.
7. Test the Water Solenoid
Locate the water solenoid, usually connected to the water inlet valve. Disconnect the wires from the solenoid and connect the multimeter leads to the terminals. Set the multimeter to the resistance setting. If the solenoid is functioning properly, it should display a resistance of approximately 100 ohms.
8. Test the Drain Pump
Disconnect the wires from the drain pump and connect the multimeter leads to the terminals. Set the multimeter to the continuity setting. If the drain pump is working correctly, the multimeter should beep when the leads are connected.
Replacing the Control Board
If the testing procedures confirm a faulty control board, you will need to replace it. Follow these steps:
1. Disconnect the dishwasher from the power outlet and water supply.
2. Remove the old control board.
3. Connect the new control board to the wiring harnesses.
4. Secure the control board in place.
5. Reinstall the dishwasher and reconnect the power and water supply.
