How to Replace a Dishwasher Control Board

Replacing a dishwasher control board is one of the easier appliance repairs. On most models it takes 20 to 45 minutes with basic tools. Here is the general process; details vary by brand.

Before you start

  • Confirm the board is the problem: no power to the panel, a dead or unresponsive touchpad, cycles that will not start, or a board with visible burn marks.
  • Find the part number on the old board. Some dishwashers have two boards: a main control board near the bottom and a user interface board in the door. Make sure you order the right one.
  • Take a photo of every connector before you unplug anything.

Safety first: always unplug the appliance and shut off the water (and gas, if any) before you open any panel. If you are not comfortable working with electrical parts, call a qualified technician.

Steps

  1. Turn off power at the breaker and shut off the water supply.
  2. Locate the board. On many Whirlpool, KitchenAid and GE models the control is inside the door: remove the screws on the inner door edge and separate the outer panel. On many Bosch, Samsung and LG models the main board sits behind the bottom kick plate.
  3. Unplug the connectors one at a time. Press the locking tabs; never pull on the wires.
  4. Remove the old board from its housing or bracket.
  5. Install the new board in the same position and reconnect every connector using your photos.
  6. Reassemble the door or kick plate, restore power and water.
  7. Run a short test cycle and watch for leaks and error codes.

Tips

  • Some boards, especially on Bosch dishwashers, must match the software version for your model. Always match the full part number.
  • If the new board shows the same fault, check the wiring harness and door switch before ordering anything else.
