How to Repair a Dishwasher Hose
Repair your dishwasher hose to keep your dishes sparkling clean. (Dishes image by Towards Ithaca from

Dishwashers work by pulling in water from your home's water supply, spraying it on your dirty dishes to remove food and debris, and then pumping it into your home's sewer system. The clean water coming in and dirty water going out both travel to and from the dishwasher through a series of hoses. If either of these dishwasher hoses spring a leak, repair them as soon as possible.

  1. 1

    Shut off the electricity to the circuit on the dishwasher. The switch is usually at the main circuit of the house, depending on your installation.

  2. 2

    Open the dishwasher door. Use the screwdriver to unscrew the mounting screws holding the dishwasher in place.

  3. 3

    Pull the dishwasher out of its location so you can gain access to the hoses.

  4. 4

    Turn off the water supply valve underneath the sink if the leak is coming from the water supply hose.

  5. 5

    Clean off the area surrounding the leak with the rags. Allow it to dry before applying the tape.

  6. 6

    Wrap the leak with repair tape. Start about 2 inches below the leak. Wrap the tape in a clockwise fashion along the outside of the hose, overlapping the previous turn with at least 1/2 inch of tape.

  7. 7

    Restore power to the dishwasher circuit. Turn the water supply back on, if necessary

  8. 8

    Run an empty load in the dishwasher. Watch the hose repair section for leaks. Wrap with more tape if necessary.

Tips and warnings

  • Replace the leaking hose as soon as possible. Repairs with tape are, at best, temporary.
