How to Repair Dishwasher Leaks


Leaky dishwashers are more than just an annoyance. They can warp wood floors, cause accidental slips and waste water. Check your dishwasher every time it runs to ensure that it does not have a roof or plumbing leak. Find your dishwasher's manuals, so you can locate all the parts for repair. It is cost-effective to try to repair your dishwasher without making a service call that can cost over $100. Repair your dishwasher yourself and enjoy the fruits of your labor with clean dishes.

Things You'll Need

  • Screwdriver
  • Gasket
  • Run your dishwasher and look for drips directly under the door. If you don't have any drips, then unscrew the cover plates located on the bottom when the dishwasher is finished running.

  • Check that the water intake line and intake valve are tightly fastened. If they have come apart, tighten them by hand. Test the dishwasher door to see if it has come loose.

  • Look for the adjustable latch plate on the top of the dishwasher. By adjusting this plate, you can get a tighter door seal. Screw the plates and test the door to find the right spot where the door fits snuggly.

  • Check the gasket. The gasket is the rubber strip that seals in the door. Examine the gasket to see if it looks worn or has cracked. If so, then you need to have it replaced.

  • Purchase a gasket from your local hardware supply store or dishwasher dealer. Soak the gasket in warm water to loosen it up for installation. Unscrew the old gasket off and screw in the new gasket.

Tips & Warnings

  • Refrain from using liquid dish washing soap in your dishwasher, because it will bubble up and leak from the appliance. Only use a detergent made for dishwashers.
  • Avoid electrocution by turning off the electricity to your dishwasher during the repair.
