How to Repair a Kitchenaid Dishwasher

When your KitchenAid dishwasher stops working correctly, take steps to fix it yourself before calling a professional. Not only will you save money, but the job will be done much faster. Repair calls can take more than a week to fix your machine, and may cost more than $100 even for a basic fix. When a KitchenAid malfunctions, you can find the source of the problem and correct it, even without experience.

Step 1

Go to your circuit breaker box and look at the breaker that operates the area where the dishwasher is. Most boxes will have a map or instructions on the door. If the switch is flipped to the "Off" position, flip it on. Check the temperature on your hot water thermostat if your dishes aren't getting clean. It needs to be at least 120 degrees Fahrenheit to be effective. Once you've ascertained that the problem is the dishwasher, not the hookups, close the door tightly and select the correct buttons to work the machine.

Step 2

Disconnect the power to the KitchenAid dishwasher. Remove the caps from the back of the sliding trays and pull them out of the machine. Manually spin the spinning arm at the base of the dishwasher to make sure it turns freely. Unscrew the cap at the top of it. Pull the spinning arm free. Check the base and the arm for refuse. Remove any debris you find, and then clean the part and replace it.

Step 3

Draw out the screw holding in the float switch -- the round plastic part near your dishwasher door. Pull the cap straight up and off the float switch once the screw is removed. Clean the float switch and cap with a toothbrush and a soft sponge, clearing any debris that might be blocking proper use.

Step 4

Run your fingers along the machine seals if it's leaking. One may have come loose, or there could simply be dirt creating spaces for water to escape. Clean out any dirt and reattach the seal with waterproof glue. Check the bracket holding your KitchenAid in place under the counter -- it's at the top of the machine. If it's loose, tighten it and then jostle the machine to check the fit.
