How to Fix a Leaky Dishwasher and Prevent Leaks



If your dishwasher is leaking, it may surprise you to find that this can be a common problem. Leaks can cause a lot of damage to your floors and cabinets, so it is important to address the issue as soon as possible. We have some helpful tips on how to fix a leaky dishwasher and maintain your dishwasher in order to prevent leaks from happening in the first place.

Top Tips For How to Fix a Leaky Dishwasher 

Whether it’s a huge leak or just a few drops, here are the steps you need to know for how to fix a leaky dishwasher:

Leaking From the Dishwasher Hoses

If you find your dishwasher leaking from underneath, it may be coming from the hoses. Make sure that the water supply hoses and drainage hoses are securely attached and don’t have any visible signs of cracking or tearing.

  • Hose clamps and connections can loosen over time, so it is important to take a good look at the hose clamps and make sure they are tight.
  • Look for clogs or blockages in the hoses, as these can cause water to back up and leak out. If the clog is accessible, remove it with a small brush or it should be replaced if you can’t remove the block.
  • Next inspect the hoses for cracks, holes, or bulges. If you find any of these issues, the hose will need to be replaced.
  • Finally, look for kinks in the hoses, which can be caused by incorrect installation or poor routing of the water supply lines. If you find any kinks, straighten them out and inspect again for any potential damage.

Leaking Dishwasher Door

The door gasket is the rubber seal that runs along the edge of the dishwasher door. If the leak is coming from a dishwasher door, it could be a sign that the door gasket is damaged. It is important to inspect the gasket for any signs of damage or wear and tear. If you notice any cracking or fraying, it may be time to replace the door gasket.

Dishwasher Filter Clog

If your dishwasher is leaking from the bottom of the door, it could be an indication that the water filter is clogged. This can leave you with a dishwasher not draining water which can eventually lead to a leak. It is important to regularly clean or replace the filter in order to prevent this issue from occurring.

To clean your filter, simply turn off the dishwasher, then remove and rinse the filter in warm water until clean. You can usually find the filter located near the bottom of the dishwasher and twist it counterclockwise to remove it. If your filter is beyond saving, you will need to replace it with a new one.

Make Sure Your Dishwasher Is Level

A dishwasher that is not level can cause a leak, so it is important to make sure that your dishwasher is sitting level on the floor. You can do this by using a spirit level or bubble level to check for any slopes or uneven surfaces. If the dishwasher is not level, you will need to adjust its legs until it is.

Using the Wrong Dishwasher Soap

Using the wrong type of dishwasher soap can also cause a leak. It is important to choose the right detergent for your machine, as some soaps are too thick and can result in clogs and leaks. The wrong soap will also likely result in your dishwasher not cleaning properly. If you are using regular dish soap, it will cause an abundance of suds and lead to suds bursting out of the dishwasher. It is best to stick with detergents that are specifically designed for dishwashers.

With these tips for how to fix a leaky dishwasher in mind, you should now feel confident in tackling the issue of a leaky dishwasher.
