3. Installation Guide
Follow these steps to replace the washing machine computer board:
- Disconnect Power: Unplug the washing machine from the electrical outlet and turn off the circuit breaker for the appliance.
- Access the Control Panel: Depending on your washing machine model, you may need to remove the top panel or access the rear of the machine to reach the existing computer board. Refer to your washing machine's service manual for specific access instructions.
- Locate the Old Board: Identify the existing computer board. It will typically be secured with screws or clips and have multiple wire harnesses connected to it.
- Document Connections: Before disconnecting any wires, take clear photos or make a diagram of all wire harness connections to the old board. This is crucial for correct re-connection.
- Disconnect Wiring: Carefully disconnect all wire harnesses and connectors from the old computer board. Be gentle to avoid damaging the connectors or wires.

- Install New Board: Position the new Hisense WFHV7012 2020116 computer board in the same location as the old one. Secure it using the original screws or clips.
- Reconnect Wiring: Using your photos or diagrams, carefully re-connect all wire harnesses and connectors to the corresponding ports on the new board. Ensure all connections are firm and correctly seated.
- Reassemble: Reattach any panels or covers that were removed to access the board.
- Restore Power: Plug the washing machine back into the electrical outlet and turn on the circuit breaker.
4. Operation
Once correctly installed, the computer board operates automatically as an integral part of your washing machine's control system. It manages various functions such as wash cycles, water levels, and spin speeds. There are no specific user operations directly on the board itself. For instructions on how to select wash programs and operate your washing machine, please refer to your washing machine's primary user manual.
5. Maintenance
The computer board is a sealed electronic component and requires minimal maintenance. To ensure its longevity:
- Keep the area around the board dry and free from moisture.
- Avoid exposing the board to extreme temperatures or direct sunlight.
- Do not attempt to clean the board with liquids or abrasive materials. A soft, dry brush or compressed air can be used to remove dust if necessary, with power disconnected.
- There are no user-serviceable parts on the board. Any internal issues require professional repair or replacement.
6. Troubleshooting
If your washing machine experiences issues after replacing the computer board, consider the following:
- No Power: Double-check that the washing machine is properly plugged in and the circuit breaker is on. Verify all power connections to the board are secure.
- Incorrect Functionality: If the machine is not performing expected cycles or displaying errors, re-check all wire harness connections to ensure they are correctly attached according to your documentation from step 4 of the installation.
- Display Issues: If the digital display on the board (visible from the rear, Figure 2) is blank or shows incorrect information, ensure the display ribbon cable (if applicable) is securely connected.
- Compatibility: Confirm that the model number and specifications of the installed board precisely match your washing machine's requirements.
If troubleshooting steps do not resolve the issue, it is recommended to seek assistance from a qualified appliance technician.
