The selector switch identifies which cycle is to be used. If a button on the selector switch does not work, that cycle will not function properly. Replacing the selector switch can restore the proper functioning of your dishwasher.
Caution: Please read our safety information before attempting any testing or repairs.
Important Safety Notice: Before replacing the selector switch, unplug the dishwasher or shut off the power at the fuse box or breaker panel to avoid an electrical shock hazard.
Tools and Materials Needed
- Screwdriver (Phillips and flat-head)
- Needle-nose pliers
- Replacement selector switch
- Safety gloves
- Labels or masking tape (for labeling wires)
Steps to Replace the Selector Switch
Step 1: Safety First
- Turn Off Power: Ensure that the dishwasher is unplugged or the circuit breaker is turned off to prevent any electrical shock.
Step 2: Access the Control Panel
- Locate Screws on the Front: Start with the door closed and locate any screws on the front of the door that must be removed. Usually, there are one or two screws near the latch; do not remove the latch itself unless necessary.
- Open the Door: Open the dishwasher door and remove the screws near the top. Check for screws along the top of the door as well.
Step 3: Remove the Control Panel or Door Panel
- Remove Control Panel Screws: On some dishwashers, the control panel can be removed separately. Start with the screws labeled “B” and attempt to remove the control panel. If the control panel cannot be removed separately, proceed to the next step.
- Remove Door Panel Screws: If the entire door panel needs to be removed, remove the screws along both edges of the door (labeled “A” and “B”). There may be several screws near the bottom of the door that secure the door to the door hinge mechanism; it should not be necessary to remove these screws.
- Lift the Panel Off: Carefully lift the panel off from the door. The panel may have wires connected, so check before lifting the panel out too far. If the panel does not lift out, check for other screws.
Step 4: Access the Selector Switch
- Remove Control Panel Cover: Remove the control panel cover to expose the door’s control components. It may be held in place with additional screws or clips.
Step 5: Disconnect the Wires
- Label the Wires: The selector switch will have wires connected to it. Use labels or masking tape to mark the wires and their corresponding terminals for proper reconnection later.
- Remove Connectors: Firmly pull the connectors off the terminals. Do not pull on the wires. You may need to use needle-nose pliers to remove the connectors.
Step 6: Remove the Old Selector Switch
- Detach the Switch: The selector switch is usually secured with screws or clips. Use a screwdriver to remove any mounting screws or release the clips holding the switch in place.
- Remove the Switch: Carefully remove the selector switch from the control panel.
Step 7: Install the New Selector Switch
- Attach the New Switch: Position the new selector switch in place and secure it with mounting screws or clips.
- Reconnect the Wires: Attach the wires to the correct terminals of the new selector switch, ensuring the connections match the labels or markings you made earlier.
Step 8: Reassemble the Dishwasher
- Replace the Control Panel Cover: Secure the control panel cover with screws or clips.
- Reattach the Door Panel: Replace the door panel by aligning it properly and securing it with screws along the edges.
- Close the Door: Ensure everything is properly aligned and close the dishwasher door.
Step 9: Test the Dishwasher
- Restore Power: Turn the power back on at the fuse box or breaker panel.
- Run a Test Cycle: Run a short test cycle to ensure the dishwasher operates correctly and the new selector switch functions properly.
Tips and Warnings
- Consult the Manual: Always refer to your dishwasher’s user manual for specific instructions related to your model.
- Use Genuine Parts: Use genuine replacement parts for optimal performance and longevity.
- Seek Professional Help: If you are unsure about any step or if the problem persists, consider seeking help from a professional technician.
By following these steps, you can effectively replace the selector switch in your dishwasher, ensuring it operates correctly and efficiently. Regular maintenance and timely repairs will help extend the lifespan of your appliance.
