⚠️ Safety Warning: Appliance repair involves electricity, gas, and moving parts. Always disconnect power before working on any appliance.
Error Code: IC3 Difficulty: Hard
Problem: Communication error with the main control board.
How to Fix IC3 Error (Step-by-Step)
- Disconnect Power and Water: Turn off the circuit breaker for the dishwasher and shut off the water supply valve, usually located under the sink.
- Remove the Kickplate: Unscrew the bottom access panel (kickplate) at the front of the dishwasher to gain access to the internal components.
- Locate the Main Control Board: The main control board is typically housed in a plastic case mounted to the floor of the dishwasher.
- Photograph the Connections: Before disconnecting anything, take a clear photo of the wire harnesses and their connection points on the control board. This will be your guide for installation.
- Disconnect and Remove the Old Board: Carefully unplug all wire harnesses from the old control board. Then, release the locking tabs or remove the screws holding the board’s housing in place and remove it.
- Install the New Control Board: Mount the new control board in the same position as the old one. Using your photo as a reference, reconnect all the wire harnesses to their correct terminals on the new board.
- Reassemble and Test: Reattach the kickplate, restore power at the circuit breaker, and turn the water supply back on. Run a test cycle to ensure the dishwasher is operating correctly.
- Turn the appliance off, wait about 2 minutes, then turn it back on.
