Dishwasher Leaking: How to Repair a Leaky Dishwasher

While your dishwasher may be your most prized household appliance, did you know that if it starts leaking, it can be one of the most expensive machines there is?

High utility bills from a leaky dishwasher and insurance claims for water damage from a major dishwasher leak can cost thousands of dollars—way more than the cost of a new appliance and a serious dent in your budget.

These modern-day time-savers require very little maintenance, so you may not notice right away if your dishwasher is leaking. You may mistake a little water on the kitchen floor from the sink or attribute a wet spot inside your cabinet to some excess condensation, but a little investigation could help you avoid a major catastrophe.

We've put together a list of things to check for, some of the most common problems, and how to repair a dishwasher that's leaking on your own.

 

Looking for the Leak

Water leaks around the door could be from a faulty gasket, cracked spray arm, or stuck float. A water leak from under the dishwasher could mean you’ve got a pump, hose, or water inlet problem on your hands.

Troubleshooting the Problem

The spray arm inside your dishwasher is located on the floor of the unit. The arm turns during the wash and rinse cycles and sprays water onto the dishes. Check the spray arm for cracks, warping, or blocked holes.

The water level inside your dishwasher is controlled by a float. Turn off the machine mid-cycle and open the door. If the water level is above the heating element, the float may be defective.

Removing the kickplate or access panel at the bottom of your dishwasher will provide a glimpse underneath the appliance where you can inspect the water inlet valve, hoses and clamps, and pump or pump gasket. Look for leaks from cracks, tears and loose connections while the dishwasher is running.


Repairing the Dishwasher

  • Replacing the gasket—open the dishwasher door and peel the gasket away from the door or tub. Clean the area with warm, soapy water. Heat the new gasket with a hair dryer and then press the new gasket into position.

  • Replacing or cleaning the spray arm—take the lower rack out and unscrew the spray arm (turning it counter-clockwise). Clean and remove any blockage.

  • Replace a damaged spray arm by screwing in the new part in a clockwise motion. Put the lower rack back into the dishwasher.

  • Change the float height—change the float switch (under the round float in the bottom of the tub) to lower the water level.

Turn off the water and electric circuit to your dishwasher before repairing or replacing the parts listed below.

  • Replace water inlet valve—first remove the hoses, screws, and the spring clamp. Replace with a new inlet valve and reattach connections.

  • Fix loose or damaged hoses—tighten loose hose clamps with a screwdriver or remove the clamps, replace faulty hoses, and reattach the clamps.

  • Pump replacement—this is a complex procedure that should be completed by a professional technician.
