Dealing With a Leaking Dishwasher Drain Hose

If there’s water leaking from your dishwasher or if your dishes are unusually dirty, you may be dealing with a leaking dishwasher drain hose. If that’s the case, it’s time to locate and fix the leak.

Why Is My Dishwasher Drain Hose Leaking?

Your dishwasher has two main lines: the main water supply and the drain hose, which connects the dishwasher to the garbage disposal or a tailpiece under the kitchen sink.

A decomposing hose gasket may be causing the issue, or vibrations from your dishwasher may have shaken the drain hose loose on one end.

How to check your dishwasher drain hose for leaks

  • Make sure that no one can turn it back on while you're working. If you can't turn off the electricity for any reason, assume that every wire is hot with electrical power and be very careful.

  • At the base of your dishwasher, there is a panel that blocks the plumbing under the dishwasher. Remove the two screws holding the panel in place, then take off the panel.

  • Check the area to see if the leak is coming from the lines or the dishwasher itself. If it's coming from the main water line, you'll see dripping even with the dishwasher off.

  • If you don't see any active drips, clean up the puddle to make it easier to spot leaks. Once the area is dry, turn the dishwasher back on. Be careful not to touch any wiring while the dishwasher is running. Use a flashlight to look under the dishwasher and watch for new leaks as it goes through the various cycles.

    If the dripping isn't coming from one of the tubes, that means the dishwasher itself is leaking. If it drips only when it's draining water, then the drain line is your culprit.

If you haven't cracked the code on your leak, consider other reasons for water under the dishwasher.
