What To Do When Your Dishwasher Is Leaking

WRITTEN BY: Mark Romero


Dishwashers are now a standard appliance that’s a must-have in every kitchen. They help us clean and sanitize dishes, cut down on time it takes to do so, and save money on running water. But what do you do if your dishwasher leaks suds all over the kitchen floor? Read on to learn the most common reasons your dishwasher may leak, some troubleshooting tips, and how to handle your dishwasher leaking.

Why is My Dishwasher Leaking?

There are multiple reasons why your dishwasher might be leaking. Still, fixing the problem quickly is essential before it becomes costly. Locating the source of the leak is the first step in knowing how to fix it.

Incorrect Dishwasher Detergent

Many people don’t know that regular dish soap can cause dishwashers to leak. It creates too many suds, which can cause the water to force itself through the door gasket and into your kitchen.

Problems with the Spray Arm

The spray arm is the part of the dishwasher that contains the water jets. This arm is responsible for spraying water on dishes and other appliances. When this arm has issues, it can cause your dishwasher to leak. Check regularly for clogs or blockages. Otherwise, you’ll typically only notice when it’s in the middle of a wash cycle and water begins leaking out of the bottom of the dishwasher.

Water Levels

If the water level in the dishwasher is too high, it can leak. If your dishwasher has been installed on an uneven surface, it may prevent the water from accessing the dishwasher drain.

Clogged Filter

Dishwasher filters are a crucial part of the dishwasher that’s responsible for filtering water in the machine. They help to make sure that clean water is being used to wash dishes, and they also ensure that no food particles are left behind.

It’s essential to check and clean the filter regularly to prevent clogs.

Damaged Seal

Dishwashers have a watertight seal that keeps the water from spilling out. If this becomes damaged, loose, or missing, it can cause water to leak into your kitchen.

Issues With the Water Inlet Valve

A dishwasher is a complex machine that has many moving parts. When it’s not maintained correctly, it can result in leaking and broken valves. The water valve could have a problem, leading to water all over your kitchen.

What To Do With a Leaky Dishwasher

Dishwashers are a standard appliance in most households. However, just like any other appliance, they can develop problems. This is when you need to know how to fix the problem.

Turn Off the Water Supply

The first thing you’ll need to do is turn off the water line to the dishwasher. Next, you’ll want to mop up as much water as possible to prevent water damage to your kitchen.

Find the Source of the Leak

Sometimes, it may be apparent where the leak is. Suppose you catch a leak happening in the middle of a dishwasher cycle. In that case, you can tell immediately where it’s coming from. Other times, you may have noticed water coming from the bottom of your dishwasher.

You may have to remove the kickplate to get a better look at the different parts of the appliance that could be causing the issue. This may require a screwdriver, so check this after you’ve mopped up the water.

Repair or Replace

If you notice any leaks, the best option is to repair them rather than replace the entire dishwasher. This is because repairing a leak will cost less than replacing a complete machine. Check if your dishwasher is still under warranty, as the manufacturer may be able to fix it for you.

Call a Professional

Sometimes, more than DIY is needed to get the leak fixed. Consider calling a professional to look at the dishwasher in this case. Calling in an appliance repair service may be a good idea. Especially if you need more clarification on what needs fixing or aren’t fully confident in your DIY repair abilities.

How to Prevent Dishwasher Leaks

Dishwasher leaks are a common problem in the kitchen and can be inconvenient. There are a few things you can do to prevent dishwasher leaks from happening.

Check the Rubber Seal

Ensure that your dishwasher door seals properly. When you close the dishwasher door, it should seal tightly against the dishwasher door frame. This seals in water that could escape and spill onto your floor and countertops. If you notice any gaps, water can leak into your home.

Clean Regularly

Use soapy water to clean the rubber gasket on your dishwasher door. This will help prevent water from seeping into the unit and causing leaks or cracks in your dishwasher door seal.

Air Circulation

Maintaining sufficient air circulation around the seal is one of the most critical factors in eliminating moisture build-up on dishwasher doors. By allowing dry, fresh air in and out of your dishwasher, you will be able to avoid the formation of mold and mildew that can cause significant damage over time.


What causes a dishwasher to leak from the bottom?

Many factors can cause a dishwasher to leak from the bottom. However, the most common causes are a faulty seal, a defective drain hose, or a clogged filter. If any of these components fail, it will result in water leaking from your dishwasher’s bottom drawer.

What is the easiest way to fix a leak in a dishwasher?
