Whirlpool Dishwasher Leaking Underneath? (Step-By-Step Solution!)

Whirlpool dishwashers are known for being resilient but leaks can occur.

If you notice water spilling out onto the floor, it’s essential to look at what’s going on. This includes understanding why your Whirlpool dishwasher is leaking from underneath.

A dishwasher can start leaking from underneath when the door’s seal is damaged or the wash arm support is loose. This causes water to spray out between the housing and wash arm support. As the water builds up, it will begin to leak through the bottom of the door. To fix the dishwasher, it’s important to tighten the wash arm support, check the door’s seal, and look for potential cuts or tears in the gasket.

These are the most important details to think about when it comes to a Whirlpool dishwasher that’s leaking from the bottom.

This article will dive deeper into showing how to repair a Whirlpool dishwasher leaking from underneath.

How To Fix Leaking Whirlpool Dishwasher

1. Shut Off The Water Supply

The first thing you are going to do is shut off the water supply.

Let the dishwasher drain and then begin working on the fix. You do not want the water to start spraying everywhere as you begin to test different parts inside.

You will also want to make sure there is no sitting water inside or outside the dishwasher. This should be cleared up before you begin working on the dishwasher repair.

The reason for doing this is to make sure you are spotting new leaks later on when the issue has been fixed. Otherwise, you might get confused as to what is from before and what is happening right now.

Take your time to scrub away the moisture and ensure you are working with a clean slate. This will ensure you end up with the type of result that is worthwhile.

Focus on doing this before fixing a Whirlpool dishwasher leaking from the bottom right corner. The same goes for a Whirlpool dishwasher leaking from the bottom left corner.


2. Check The Seal

You will want to check the seal.

This is often a problem with Whirlpool dishwashers that have been damaged. The seal begins to come off and that is the first thing you are going to want to take a look at around the edges.

See what is causing the dishwasher door to not keep the water inside. This is why the seal is important and it needs to be intact.

Your goal has to be to check the seal, see where the damage is, and then replace it. This is often the main reason for water leaking out of the dishwasher along the bottom.

3. Check The Wash Support Arm

Let’s assume the seal is okay.

Another issue can have to do with the wash support arm along the bottom of the Whirlpool dishwasher. This is a part of the dishwasher that can go unnoticed but it will cause water to spray in all directions.

The wash arm support is supposed to be tightly attached to the housing inside. If it is not, the water is going to start spraying everywhere and that is when it becomes important to tighten the parts before it gets worse.

Due to how much water builds up inside the dishwasher, it’s common for it to start leaking out.

The only way to fix this is to replace the wash arm support or tighten it.

4. Test The Dishwasher

This issue revolves around the dishwasher not being tested as much as it needs to be.

You have to make sure to run the dishwasher after you have fixed the seal and/or wash arm support. This is the only way to make sure water doesn’t start spraying as soon as you run a full cycle.

Test it on empty and see where the water goes.

If it stays inside, this means you have fixed the problem and water will not be leaking out. If it is still leaking, you might have to replace the housing around the wash arm support or rework the dishwasher door seal.

Final Thoughts

These are the tips to focus on with a Whirlpool dishwasher leaking from underneath.

If a Whirlpool dishwasher is leaking from underneath, the main issue will have to do with a damaged door seal. This can cause water to leak out from the sides and bottom. It is also possible for the wash arm support along the bottom to be damaged. Test both of these issues to see where the problem lies.

In most cases, this is going to be an easy fix and you should be able to get the dishwasher back to how it was.
