4 Reasons Why Your Dishwasher Might be Leaking

Why is your dishwasher leaking? Dishwasher leaks are funny in sit-coms but somehow at home, you wind up with a murky puddle instead of a kitchen full of bubbles to play in. In real life, dishwasher leaks are not so funny and you need a solution as soon as possible. The first step to that solution is knowing what’s wrong. There are four most common reasons why your dishwasher might be leaking that can be investigated DIY. Let’s take at these causes, how to identify them, and what to do. 

Clogged Drain

The first thing you can check and the easiest thing to fix is the dishwasher drain. The drain in your dishwasher needs to flush food bits as well as dirty and soapy water. If the drain gets clogged with food or even lost bits of plastic (this can happen), then the drain will back up and this can cause a leak.

Fortunately, checking is simple. Open up your dishwasher and pull out the bottom rack, or both racks, to make room. Find the drain, this is usually obvious and often has a dome or hex-shaped cover. The cover and the drain together should be filtering food and some dishwashers even have their own garbage disposal blade. But all this can become clogged.

Look for signs of food stuck to the drain filter and inside the drain itself. Switch off the dishwasher before investigating the drain too deeply. 

Unleveled Feet

Grab a bubble level and test the bottom line of the dishwasher. If the dishwasher isn’t level, that could be your problem. The floor of your dishwasher is designed to flow water toward the drain. If the dishwasher isn’t level, the floor will drain water incorrectly and the water goes where it’s not supposed to.

Leveling the feet is a simple task that might be challenging, depending on how your dishwasher is mounted in the cabinet. Ideally, the best way to level your dishwasher is to twist the feet. Twisting clockwise shortens a foot, twisting counter-clockwise lengthens a foot. Do this until your bubble level reads that the bottom of your dishwasher is properly level. 

Soap That is In Use

If soap that is not meant for a dishwasher is being used, it will create suds that will overflow the dishwasher and leak out the front door. Be sure to check the soap being used and that you are only using soap designed for dishwashers.

Broken or Loose Water Lines

Finally, there are the water lines. It’s possible that one of your lines broke or one of your valves is broken or loose, allowing water to flow where it’s not supposed to. If the water is coming from underneath your dishwasher instead of from inside or from the door, then you’re more likely to be looking at a water line or valve problem. You can take a look by taking off the kick-plate. Under there, you may be able to spot damage or the source of the leak.
