How to Tell If Your Washing Machine Control Board Is Bad

Have you ever found yourself staring at your washing machine, wondering why it’s not working properly? One of the most common culprits is a faulty control board. This essential component is responsible for managing the machine’s functions, including water temperature, spin speed, and cycle settings. When it malfunctions, it can cause a range of problems that can make doing laundry a nightmare. In this comprehensive guide, we’ll delve into the signs and symptoms of a bad washing machine control board, providing you with the knowledge you need to troubleshoot and resolve the issue.

Symptoms of a Faulty Washing Machine Control Board

If your washing machine is experiencing any of the following issues, it may be a sign that the control board is malfunctioning:

  • The machine won’t start: If the control board is not functioning correctly, it may fail to send the necessary signals to the other components, preventing the machine from starting.
  • Random cycle interruptions: A faulty control board can cause the machine to stop unexpectedly during a cycle, leaving your clothes wet and unwashed.
  • Incorrect water temperature: The control board is responsible for regulating the water temperature. If it’s malfunctioning, the water may be too hot or too cold, damaging your clothes or preventing them from being cleaned properly.
  • Overfilling or underfilling: The control board is also responsible for controlling the amount of water that enters the machine. If it’s faulty, the machine may overfill or underfill, leading to leaks or inadequate cleaning.
  • Excessive noise: A malfunctioning control board can cause the machine to make unusual noises, such as grinding, squealing, or banging.

How to Test the Washing Machine Control Board

If you suspect that your washing machine control board is faulty, there are a few simple tests you can perform to confirm the diagnosis:

  • Ohmmeter test: Turn off the power to the machine and disconnect it from the electrical outlet. Remove the control board from the machine and use an ohmmeter to test the continuity of the board’s components. If any of the components show an open circuit, the board is likely faulty.
  • Visual inspection: Look for any obvious signs of damage on the control board, such as burnt marks, broken wires, or loose connections.
  • Check for error codes: Some washing machines have a diagnostic system that displays error codes when there’s a problem with the control board. Consult your owner’s manual to see if your machine has this feature.

Tips for Troubleshooting a Faulty Washing Machine Control Board

If the tests confirm that the control board is bad, there are a few steps you can take to troubleshoot the issue:

  • Reset the machine: Unplug the machine from the electrical outlet for a few minutes and then plug it back in. This may reset the control board and resolve the issue.
  • Check the wiring: Make sure that all of the wires are securely connected to the control board. Loose or damaged wires can cause the board to malfunction.
  • Clean the board: If the board is dirty or dusty, it may cause the board to malfunction. Use a soft cloth and rubbing alcohol to clean the board.
