How to Tell If Your Washing Machine Control Board Is Bad

Signs of a Faulty Washing Machine Control Board

A washing machine control board, also known as the main control board or electronic control board, is a vital component that regulates various functions of your washing machine. It controls everything from water temperature and cycle settings to motor speed and timing. When this control board malfunctions, it can disrupt the normal operation of your washing machine. In this article, we will explore some common signs that indicate a faulty washing machine control board.

1. Unresponsive Controls

One of the most obvious signs that your washing machine control board is bad is when the controls become unresponsive. If you press the buttons on the control panel and nothing happens, or if the display doesn't light up, it is likely that the control board has failed. However, before jumping to conclusions, make sure to check if the control panel is properly connected and if there are any loose wires.

2. Erratic Behavior

If your washing machine starts behaving erratically, such as starting or stopping abruptly during a cycle, changing settings on its own, or displaying inconsistent error codes, it may be due to a faulty control board. The control board is responsible for interpreting and executing the commands you input through the control panel. When it malfunctions, it can result in unexpected and erratic behavior.

3. Failure to Start or Complete a Cycle

A malfunctioning control board may prevent your washing machine from starting or completing a cycle. If you encounter issues like the machine failing to start after pressing the start button or getting stuck in the middle of a cycle without completing it, it could be an indication of a bad control board. Before assuming it's the control board, however, ensure that other potential causes, such as a faulty door latch or a problem with the power supply, have been ruled out.

4. No Power or Display

If your washing machine doesn't turn on at all or if the display remains blank, it could be due to a defective control board. The control board receives power from the main power supply and distributes it to various components of the washing machine. If the control board fails to transmit power or if it gets damaged, it can result in a complete power failure.

5. Burning Smell or Burn Marks

In some cases, a bad control board may emit a burning smell or have visible burn marks on its surface. This usually occurs when there is a short circuit or a component on the board has burned out. If you notice any burning smell or burn marks, it is crucial to disconnect the power supply immediately and seek professional assistance.
