How to Change the Electronic Card of a Washing Machine

Jul 10, 2023, 11:09am

The electronic card of a washing machine, linked to the control panel of your washing machine, is the part that manages the operation of your appliance. It allows you to start programs, send commands to other parts or simply display information on the screen.

There are different types of electronic cards: the power card, and the display or control card.

The power card ensures the proper functioning of the control system of your washing machine. It allows the components of the device to be supplied with electricity.

On many washing machines, the power board is separate from the control or display board. However, there are also washing machines with a single electronic card: it then brings together the power card and the display card.

To differentiate them:

  • the power board is often bigger than the display board, there are more components on it and they are bigger (black cubes, wire coil spheres, relays, capacitors…). It may be at the bottom of the washing machine, in a protective plastic box. On some washing machines there are several power boards, which supply power to different parts.
  • the display or control board is often smaller, it sits behind the washing machine’s control panel and powers buttons and a small screen.

If a washing machine no longer turns on, it will be necessary to check that the current is indeed reaching the power board, while the display board will be rather linked to problems with the display or the definition of the screen, the button malfunctioning or unresponsive.

The electronic card is located just behind the control panel which will have to be removed to replace it.

The electronic card, also known as the control board or PCB (Printed Circuit Board), is a vital component in modern washing machines. It controls various functions of the machine, including cycle selection, temperature regulation, and timing. If you encounter issues with your washing machine’s electronic card, such as a malfunctioning display or erratic behavior, you may need to replace it. This guide will provide you with step-by-step instructions on how to change the electronic card of a washing machine.

How to Change the Electronic Card of a Washing Machine

Safety First

Before attempting any repairs or replacements on your washing machine, it’s crucial to prioritize safety. Make sure you have unplugged the machine from the power source to prevent electrical shocks. Additionally, exercise caution when handling electronic components to avoid damaging them.

Tools Required

To change the electronic card of a washing machine, you’ll need the following tools:

  • Replacement electronic card compatible with your washing machine model
  • Screwdriver set (usually Phillips or Torx)
  • Small pliers (optional, for wire connectors)
  • Antistatic wrist strap (optional, but recommended for protection against electrostatic discharge)

Steps to Change the Electronic Card

Follow these steps to replace the electronic card in your washing machine:

Step 1: Locate the Electronic Card

The electronic card is usually housed in a control panel located at the top or rear of the washing machine. Consult your washing machine’s user manual or do a quick online search to determine the specific location of the control panel for your model.

Step 2: Remove the Control Panel

Using the appropriate screwdriver, carefully remove the screws securing the control panel in place. Set the screws aside in a safe place to avoid misplacing them. Gently lift the control panel, taking care not to damage any wires or connectors that may be attached.

Step 3: Disconnect the Wires

Identify the wires connected to the electronic card. These wires are usually color-coded and have connectors. Using your pliers or fingers, carefully detach the connectors from the electronic card. Take note of their positions or take a picture to ensure proper reconnection later.

Step 4: Remove the Old Electronic Card

Once the wires are disconnected, locate the old electronic card within the control panel. Carefully remove it by unscrewing any securing screws or brackets. Be gentle to avoid bending or damaging the card.

Step 5: Install the New Electronic Card

Take the new electronic card and align it properly within the control panel. Secure it in place using the screws or brackets you removed from the old card. Ensure it is firmly in place but be cautious not to overtighten the screws, as this may damage the card.

Step 6: Reconnect the Wires

Refer to the notes or picture you took earlier to guide you in reconnecting the wires to the new electronic card. Ensure that each wire is securely inserted into the appropriate connector. Double-check the connections to ensure they are correct and properly seated.

Step 7: Reassemble the Control Panel

Place the control panel back into its original position on the washing machine. Align it carefully, ensuring all the screw holes line up. Use the screws you previously removed to secure the control panel firmly in place.

Step 8: Test the Machine

Plug your washing machine back into the power source. Turn it on and test the new electronic card by running a wash cycle. Pay attention to the machine’s behavior, making sure all functions work as expected and there are no error messages or anomalies.

If the machine operates correctly without any issues, congratulations! You have successfully changed the electronic card of your washing machine. However, if problems persist, it may be necessary to consult a professional appliance repair technician or contact the manufacturer for further assistance.

In conclusion, replacing the electronic card of a washing machine requires caution, attention to detail, and some basic technical skills. Always refer to your washing machine’s user manual for specific instructions and guidelines, as different models may have slight variations in the replacement process. If you’re uncertain or uncomfortable performing the task, it’s best to seek professional help to ensure a safe and accurate replacement of the electronic card.
