Dishwasher Leaks When Not Running: 7 Easy Ways To Fix it Now

A dishwasher is a convenient appliance that saves time and effort in cleaning dishes, but it can be frustrating when it starts leaking water, even when not in use.

If you have noticed water pooling around your dishwasher, you may wonder what could be causing the leak and how to fix it.

In this article, we’ll look at some common reasons why a dishwasher may leak when not running and provide solutions to help you troubleshoot the issue.

Whether it’s a faulty valve or a clogged drain, understanding the root cause of the problem can help you prevent further damage and keep your kitchen floor clean and dry.

Why is your Dishwasher Leaking When Not Running?

dishwasher can leak water even when it’s not running for several reasons, including:

1. Damaged Door Seal

Every dishwasher has a door seal, which is usually a rubber gasket designed to prevent water from leaking out of the dishwasher.

Now, if that watertight seal is damaged, it can allow water to escape—as time progresses, the seal can become worn, torn, or warped, leading to leaks.

In some cases, the fix is usually straightforward, and you must clean or reposition it. But if it appears damaged, you’ll have to replace it.

2. Clogged Drain

Dishwashers have a drain used to carry dirty water out of the machine or appliance.

If the drain of your dishwasher becomes clogged with food debris and other objects, rather than draining the dirty water like it’s supposed to, the clog makes the water back up and leak out of the machine.

Your dishwasher’s drain should be cleared of food debris or any blockage you may find, and the drain filter should be cleaned appropriately as well.

3. Cracked Tub

The dishwasher tub is part of the machine holding water during the washing cycle. So if your dishwasher’s tub becomes cracked, it can allow water it’s supposed to hold to leak out of your machine.

cracked or broken dishwasher tub is a more severe issue that requires professional help to fix or replace it.

4. Faulty Water Inlet Valve

The dishwasher’s water inlet valve controls the amount of water that goes into the machine. If the water valve is faulty or damaged, it can leak water from your device.

If you notice that your water inlet valve is damaged, you’ll have to replace it to fix the leaky dishwasher problem.

5. Loose or Damaged Hose Connections

Dishwashers have hoses that connect the drain and water supply. If those connections are damaged or loose, they can cause water to leak out.

To fix the loose connection problem, check the hoses and ensure they are tightened and secured properly. If it is damaged, you’ll have to replace it.

6. Defective Float Switch

The float switch in your dishwasher is responsible for regulating the water level within the machine.

If the float switch becomes faulty, the switch will be unable to correctly regulate the water level, which can cause the dishwasher to overfill with water (excess water) and ultimately result in leaks. In this case, you’ll have to let a professional diagnose, repair, or replace the float switch.

7. Broken Pump

pump’s primary duty is to move water in and out of the dishwasher. So if that water pump becomes damaged or broken, it can cause water to leak out of the machine.

Again, this isn’t a simple problem, and it’ll require the help of a professional to repair or replace the pump.

In summary, identify the cause of the leak in your dishwasher and fix it immediately. It is essential because it helps prevent further damage to your dishwasher and home.

Suppose you are still determining the reason behind the leaks coming from your machine, or you are not comfortable carrying out the repairs yourself. In that case, you should call a professional dishwasher repair service for assistance.

How to Fix a Dishwasher Leaking When Not Running?

If you’ve determined that your dishwasher is leaking water when it’s not running, there are several potential fixes to consider. Some of these include:

1. Check the door gasket

The door gasket is the rubber seal that runs around the perimeter of the dishwasher door. If the door gasket is worn or damaged, water can leak out of your dishwasher.

To fix this problem, inspect the door gasket for tears, deformities, or cracks. If you find any problem with the door seal, you’ll have to replace the gasket.

2. Inspect the spray arms.

The spray arms are components of your dishwasher responsible for distributing water throughout the machine during a dishwasher cycle.

If your dishwasher spray arms become clogged with food particles and other foreign objects, it can cause water to leak out of your device even when it’s not running.

To fix this problem, remove the spray arms from the dishwasher and clean them thoroughly before placing them back into the dishwasher. When cleaning it, make sure that there are no clogs or blockages in the spray arm nozzles.

3. Check the float switch.

The float switch is a small component usually found at the bottom of the tub. The float switch is responsible for detecting the dishwasher’s water level and ensuring it doesn’t overfill.

However, if the float switch in your dishwasher gets stuck in the “up” position, it can cause water to leak out of your machine.

Remove the lower rack in your dishwasher and locate the float switch to fix this problem. Once you have found it, gently push it down to ensure it starts working properly (i.e., it stops water leakage).

4. Inspect the inlet valve.

The water inlet valve is a component in your dishwasher that lets water into the machine during wash cycles. If the inlet valve in your machine starts malfunctioning or is damaged, it can cause water to leak out of your device even when it’s not running.

To fix this problem, turn off the dishwasher’s water supply and remove the water inlet valve. Check it for any signs of wear or damage and replace it if necessary.

5. Check the drain hose.

The drain hose is simply the tube channeling water out of your dishwasher and into your home’s plumbing system. If your dishwasher’s hose becomes damaged or clogged, it can cause water to leak out of the dishwasher even when it is not running.

To fix this problem, remove the drain hose and inspect it for clogs or blockages. If you find any, use a plumbing snake or any other tool you prefer to clear out the debris or blockage.

6. Run a test cycle

Once you have completed all the necessary repairs, run a test cycle to ensure the leak has been fixed.

By following the steps outlined above, you’ll be able to not only diagnose the cause of your dishwasher leaks but you will also be able to fix it.

Remember, you mustn’t do the repairs yourself—if you are not comfortable plumbing or working with appliances, it’s always best to call a professional for help.


What is the main cause of the dishwasher leak?

Dishwashers leak for various reasons, but one of the most common reasons for water leaking from your dishwasher is a damaged or worn-out door seal.

Over time, the rubber gasket responsible for sealing the dishwasher’s door can become worn or cracked, and a damaged door seal can cause water to leak out of the dishwasher.

Other common causes of dishwasher leaks include damaged hoses, clogs in the drainage system, and a faulty motor or pump.

How can I tell where my dishwasher is leaking from?

To determine where your dishwasher is leaking from, you can follow these steps:

Check the door seal: Inspect the seal for any signs of wear or damage. If the seal is damaged or worn, it can cause water to leak through it. Close the dishwasher door and run a cycle to ensure the door seal is the culprit. Inspect the area around the door for any signs of water leaks.

Check the hoses: Inspect the hoses that connect the drain and the water supply. Ensure that they are properly connected and are not damaged. You can also inspect it by running a cycle and checking for leaks around the hoses.

Inspect the pump: Check the dishwasher’s pump for signs of clogs or damage. Run a cycle and inspect areas around the pump for leaks.

Check the float switch: The float switch controls the water level in the dishwasher. And once it becomes defective, it can cause water to overflow and leak out of the machine. To check the float switch, run a cycle and inspect areas around the float switch.

Inspect the dishwasher tub: If the dishwasher’s tub is cracked or damaged, water can leak. Run a cycle and check for any leaks around the tub.

It is vital to note that if you cannot perform these inspections, you should consult a professional to avoid causing further damage to your dishwasher.
