Time: 20 minutes
Your dishwasher… you love it, but do you really give it the love it deserves? If nothing else, you've got to do a yearly maintenance inspection and cleaning. Grab 20 minutes and a few tools this weekend, and make sure everything is in tip-top dishwashing shape.*
What’s in it for you?
- Improved machine efficiency
- More cleaning power
- Flood prevention
- Fewer repairs
What do you need?
- Flashlight (to peer under cupboards)

Cut Water and Power
- Turn off the power supply to your dishwasher at your home’s breaker panel. If you have access, unplug your dishwasher.
- Shut off the water supply valve, usually located under your kitchen sink.
Locate the water supply hose (leading to) and drain line hose (leading from) your dishwasher. These are usually installed within your cabinetry between your dishwasher and kitchen sink. (Note: Depending on the installation of your unit, you may or may not have access to these hoses.)
- Inspect all visible hoses and connections to determine if there are any leaks or clogs, and inspect cabinetry and flooring for signs of water damage.
- Using a flathead screwdriver or nut wrench, tighten visible hose connections to eliminate potential leaks.

Remove Buildup on Dishwasher Arms
Food particles can collect in the water holes of your dishwasher arms, preventing a quality clean.
- Remove the lower dish rack.
- Using a pipe cleaner, paper clip, or sewing needle, loosen debris from the water holes and remove any buildup from inside the spinning arms.
Pro Tip: Never use a toothpick, the tip can break off inside the washer arm.
Inspect Float Assembly
Your float assembly is located on the bottom of your dishwasher. As your dishwasher fills, a float valve in the interior tub lifts to tell the machine to stop adding water.
- Lift the float and let it drop several times to ensure it is working properly. If the float sticks, gently slide it up and down while cleaning with hot water.
- While sliding the float, listen carefully for a clicking noise. Clicking indicates the relay switch (located underneath the dishwasher) is working properly.
- If the float is stuck or you do not hear any clicking, you may need to replace your float assembly to prevent your dishwasher from overfilling.
Ensure a Tight Door Seal to Prevent Leaks
- Tip your dishwasher door down and spray cleaner or degreaser along the gasket (rubber or plastic seal around the door).
- Let sit for a moment before running a hot, wet rag over the gasket to remove food particles, ensuring a clean seal.
- Wipe the space between the door and the bottom of the tub. Food can collect here and cause mold.
- Consult your owner’s manual to determine if your dishwasher has a manual-clean filter. If so, remove the filter from your dishwasher and gently wash the filter according to the manufacturer’s instructions.
- If your filter has any tears or holes, it should be replaced immediately to protect the dishwasher pump and motor seals from damage.
Inspect the Wastewater Exit
- Inspect the inside bottom of your dishwasher where wastewater exits the appliance. If you suspect any buildup, consult your owner’s manual to disassemble the cover and clean inside the drain.
- If you find glass, inspect the pump housing for glass shards and remove. Check for seals that may have been punctured or damaged. Replace as needed.
Inspect Plastic Coating on Racks
- If the plastic coating has worn off on your dishwasher’s top or bottom racks, repair or replace the racks as soon as possible. Left alone to rust, small shards of rusty metal can enter the dishwasher pump and lead to expensive repairs.
Run Dishwasher Empty to Clean
- Fill the space in the door where you normally put the dishwashing soap with white vinegar.
- Add baking soda to the soap container, then close the door and run the dishwasher to disinfect and clean your unit.
Boom. You’re done. Have a cocktail and celebrate your clean machine.
