Leaking Dishwasher Lines Need Attention

Dishwasher lines allow your dishwasher to clean your dishes and get rid of the dirt and debris. When these lines start to leak, your dishwasher will stop working and could even cause other problems.

Check Your Dishwasher Lines

Water travels through your dishwasher through two main lines: one where the water comes in, and one where the water comes out. The water supply line feeds fresh water into the appliance. The second line is the waste line, which connects from the dishwasher to the garbage disposer (if you don't have one it connects to a dishwasher tailpiece under the kitchen sink).

These two lines work together to whisk away food and grease, leaving your dishes (and the inside of your dishwasher) sparkling. But any connection point is prone to problems; over time, wear and tear can break down the connections in the lines and cause a leak.

How to check if your dishwasher lines are leaking

  • 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 this doesn't seem to be the issue, consider other reasons for water under the dishwasher.

What To Do If Your Dishwasher Lines Are Leaking?

It's possible that simply tightening the lines at the point of connection will fix the problem, so that's the first step. If that doesn't work, consider contacting a technician to take a closer look and replace the line, if necessary.
