6 Reasons Why Bosch Dishwasher leaking [Solution]

As mentioned earlier, there are various reasons behind dishwasher leakage; we can’t specify a certain issue for this problem.

Depending upon the dishwasher model, the reason behind leakage can be different.

Some of the major reason for the dishwasher leak is the damaged door gasket, drainage issue, and faulty door latch.

These issues are some of the significant reasons for dishwasher leaks. If the issue persists, there might be a different issue for the dishwasher leaks.

In the next section of this article, we will look at all these problems and solutions you can consider to fix the leakage issue on the dishwasher.

What are the causes of Bosch dishwasher leaking?

Here we have brought 7 issues that can cause leakage issues on your dishwasher.

Damaged Gasket

A damaged gasket is the first issue I would like to consider in this list.

The gasket on the dishwasher creates a seal in the dishwasher door or dishwasher tub that ensure water leakage from your dishwasher.

If you haven’t replaced the dishwasher gasket, then I will suggest you change the dishwasher gasket. 

Though the gasket is made up of rubber, its quality decreases when exposed to water.

It can tear and create a passage to pass water from the dishwasher tub. So, I recommend you make a proper inspection of the dishwasher tub and door.

If the dishwasher gasket is ripped off, consider replacing it. 


If the water is leaking from the dishwasher, you need to change the dishwasher door seal or gasket from the dishwasher.

Here is the stepwise instruction to replace the dishwasher gasket.

  1. First of all, make sure you’ve disconnected the appliance water supply and power supply from the dishwasher.
  2. Remove the lower dishwasher rack.
  3. Locate the soft rubber seal in the dishwasher tub. 
  4. Clean the food particles from the rubber if there is blockage while removing them. 
  5. Now grasp one end of the dishwasher with your finger and pliers and remove the existing gasket from the dishwasher. Make sure to note down the orientation of the gasket while removing it. It will help you while installing a new gasket on your dishwasher. 
  6. Once you remove the gasket, clean the channel with warm clothes or a brush. 
  7. Now install a new gasket on the tub. If you don’t know how to install it, take a look at the instruction manual of the dishwasher. 
  8. Once you finish installing, ensure that there should be no more than ¾ inch protruding on each side of the channel. You can use the blade to trim the excess rubber seal. 

This is how you can replace an old dishwasher gasket with a new one. I hope you have followed all the steps while replacing the gasket on your dishwasher. If there is any problem while installing the gasket, please let us know in the comment. 

Loose door latch

If the dishwasher door latch is damaged, you should replace the door latch from your dishwasher.

The dishwasher door latch creates a tight seal inside the dishwasher as it is equipped with a rubber seal.

Similarly, it is also connected with a door switch, which does not allow the dishwasher to start unless it is closed. 

If you are having difficulties opening and closing dishwasher doors, there could be a problem with the dishwasher door that is causing leakage in your dishwasher.

Make a proper inspection of the dishwasher door to ensure that there should not be any kind of obstacle or rust on the dishwasher door latch. 


First, ensure that there should not be an obstacle while closing the door.

If you are having trouble closing the dishwasher door, make sure to lubricate the grease.

Similarly, if the door latch is faulty or loose, consider replacing it with your dishwasher. 

Here is the stepwise instruction to replace the door latch in your dishwasher.

The method that we are going to discuss here may not be suitable for every dishwasher model.

But I will try to write a stepwise method that is suitable for every model of Bosch dishwasher. 

1.     Disconnect the dishwasher power and water supply. 

2.    Remove the dishwasher from the cabinet. 

3.    On the top of the dishwasher, you will see a latch assembly covered with a steel plate. 

4.    Remove all the screws from the latch assembly; this will allow you to remove the latch assembly from the dishwasher. 

5.     After removing all the screws, remove the steel plate and inside, there is another screw you should remove. 

6.    Pull that plastic cover once you remove the screw, and then remove the latch assembly from the dishwasher. 

7.     Now install a new door latch. 

8.    Pull all the screws and tighten them up. 

9.    Put your dishwasher inside the cabinet. Restart your dishwasher and see if the water is leaking or not. 

Follow the above stepwise instruction to replace the door latch on the dishwasher. If the problem persists, go to the next section. 

Problem with the drain hose

The drain hose can also cause water leakage in your dishwasher.

If the water is leaking from the bottom dishwasher hose must be cracked.

When the dishwasher hose gets cracked, water can easily leak from the cracked part.

So, make a proper inspection of the bottom of the dishwasher and make sure that the drain hose is not cracked and is tightly connected with the drain pump. 

Sometimes it can get loose due to water pressure which also causes leakage in the dishwasher.

If the drain pump is cracked, you can use duct tape as a temporary solution to stop leakage in the dishwasher.

Similarly, if you have an additional drain hose, consider replacing your existing drain hose with a new hose. 


If the drain hose is cracked, you need to replace it from your dishwasher. If you know how to replace you are good to go.

But, if you don’t, here we will discuss stepwise instructions to replace the drain hose from your dishwasher. 

1.     Remove the water supply pipe and power supply from your dishwasher. 

2.    After this, remove the dishwasher from the kitchen cabinet. 

3.    Bend the dishwasher backwards, and you will get access to the dishwasher drain pump and circulation pump. 

4.    In some dishwashers, you are required to remove the bottom panel to access the drain pump from the dishwasher. Remove all the screws and remove the panel if present. 

5.     There you will see a drain hose connected with the drain pump. 

6.    Remove the metal covering from the drain hose. 

7.     Now remove the drain hose.

8.    Install a new drain hose in the circulation pump. Make sure to tighten it up using the same metal covering you remove while removing the hose. 

This is how you can replace cracked or damaged drain hoses from the dishwasher. I hope that method was helpful while replacing the drain hose from the dishwasher. 

Faulty circulation pump

The dishwasher pump consists of two significant compartments water and drains compartment.

It pumps out water drainage from your dishwasher. If your dishwasher is leaking, the dishwasher circulation pump could be a problem. 

If there is standing water in your dishwasher after the cycle.

There could be a problem with the dishwasher circulation pump.

When the dishwasher can’t pump out drain water from the dishwasher, it causes a standing water problem. 


If the water is standing after the dish cycle, there must be a problem circulation pump.

It can also be caused due to a clogged drain filter. Therefore, first of all, make a proper inspection of the drain compartment of your dishwasher.

Clean food debris and particles from the drain compartment if present.

You can remove the drain filter and put it under the running water clean it thoroughly.

If the problem still exists, there is a problem with the drain pump.

If cleaning the drain filter and compartment does not fix the issue, there could be a problem with the dishwasher circulation pump or drain pump.

In this case, you should replace your drain pump.

To replace the drain pump, you should have the technical knowledge and proper tools while replacing the pump.

Therefore, I suggest you call the dishwasher service centre or technicians to replace the circulation pump from your dishwasher. 

Wrong Detergent

The wrong detergent is another major reason seen in every leaky dishwasher.

Excessive soapsuds cause water to leak from the dishwasher door.

A good detergent does not have more than ½ inch of suds on top of the water.

The suds can push out water from the dishwasher causing leakage and flooding on your dishwasher. 

Therefore, I always suggest everyone use the detergent recommended by your manufacturer.

If you don’t know which detergent to use. Take a look at the dishwasher user manual.

There you will find all the information about the dishwasher along with a detergent recommendation. 

What to do if the dishwasher is still leaking?

If the problem persists, I recommend you to call the Bosch service center.

Bosch offers one to two years of warranty on every dishwasher.

If your warranty period is not over, they will repair your dishwasher without any cost.

They will send technicians to fix the issue with your dishwasher.
