There are various reasons that could create leakage in Samsung dishwasher. One of the common reasons for this problem is a faulty water inlet valve.

Apart from this, there are various reasons that could cause water leakage in the Samsung dishwasher. 

Why does the Samsung dishwasher have leakage?

There are different reasons that could create water leakage on the Samsung dishwasher. If you are facing this problem in your Samsung dishwasher, you need to make a proper inspection of the issue on the dishwasher. In this article, we will discuss the top 8 reasons that can create water leakage in your Samsung dishwasher. 

8 Reason with Solution for Samsung Dishwasher Leaking

Samsung Dishwasher Leaking

Stuck Or Clogged Spray Arm

A stuck or Clogged Spray Arm is one of the major reasons that can cause the dishwasher to leak.

There are three spray arms on the dishwasher. If any of these spray arms get clogged, it can create leakage issues in the dishwasher.

Spray arms release water during the cycle to clean the dishes in the dishwasher. Sometimes, these spray arms can build up calcium and food debris which could cause dishwashers to leak.

Therefore, first of all, make a proper inspection before fixing this issue on your dishwasher. 


The first and foremost step is to inspect the problem. Check the dishwasher Spray arms if it is working correctly or not.

What I mean is it should spray the water properly during the cycle. Here is the stepwise instruction to fix this issue:

  1. Turn Off the power supply of the dishwasher. 
  2. Now look for the clogged spray arms.
  3. If there is visible debris or food particles, then clean it all.
  4. If it is hard to clean, then I will suggest you Unscrew the spray arms and clean them properly. 
  5. After this, screw up the spray arms and then run a new cycle.

This is how you can fix the leakage of spray arms. All you need to do is clean it all, and if there is calcium build-up, clean it all, and after this, it will be fixed. 

Loose Pump Seal

Loose Pump Seal is another major issue most seen in the leakage dishwasher.

If your dishwasher is having a leakage issue, there could be a loose pump seal in your dishwasher. A loose pump seal is located at the bottom of the Samsung dishwasher. 

If you bend the dishwasher a little backward, you will see two metal clamps securing each other to the flooring.

The main work of the Pump seal is to prevent water leakage in the dishwasher. If any of these Metal clamps can get loosened, they no longer prevent water leaks. 


The solution to this problem is to secure the metal clamps on the dishwasher. So, for this, you need to take out your dishwasher and bend it backward.

This will give you easy access to the metal clamps. Here is the stepwise instruction to fix this issue:

  1. First of all, turn the dishwasher backward. After this, you will see two Metal crams on the bottom of the dishwasher.
  2. Now, inspect the Metal clamps and see if they lose or not. If it is loose, then detach it from the dishwasher.
  3. After this, reattach the metal clamp again on the dishwasher and secure them properly with the help of a screw and bolt. 

Now check the dishwasher and see if there is any kind of leakage or not. If there is, then don’t worry; there should be another problem with your dishwasher.

Damaged Latch or Gasket

A damaged Latch is another culprit for the water leaking on the dishwasher. If your dishwasher door latch is damaged or cannot lock the door properly. It is more likely to leak the water from the dishwasher. 

If there is no problem with the Latch, then check the gasket of the dishwasher.

Any damage to the gasket will stop you from closing the door properly. The gasket can get damaged after years of use. Therefore, it needs to be changed in case it is damaged. 


The first step is to inspect from where the water is leaking. If the source of the leakage is the dishwasher door,

then check if the latches are aligned with the dishwasher door or not. The dishwasher latches may not align when the screw is loose. 

Therefore, I suggest you inspect the dishwasher door latches. If the Latch is broken, then I will recommend you change the latches from your dishwasher. Similarly, if the gasket is damaged, then change it too. 

Faulty Water Inlet valve

The water inlet valve is responsible for pumping water inside the dishwasher. Sometimes the inlet valve may not open or close properly,

which can build up water inside the dishwasher, causing water to leak. In this case, you can run the dishwasher cycle and open the door in the middle of the cycle. 

If there is a fault in the inlet valve, then there you will see water build-up or overfill. So, I will suggest you check the inlet valve of the dishwasher and check if there is a presence of debris or not.

If there is, then I will suggest you clean up all the dirty debris from the inlet valve. After this, check if the problem is fixed or not. 


The solution to this problem is cleaning the inlet valve. If you have cleaned the inlet valve debris, it should prevent the dishwasher from leaking water anymore.

But, if the problem still persists then, I suggest you change the water inlet valve from the dishwasher. 

We cannot do anything besides changing the dishwasher inlet valve in this situation. You can call to Samsung dishwasher or technicians to install a new inlet valve in the dishwasher. 

Wrong Detergent

The wrong detergent can also cause leakage issues in the dishwasher. It is necessary to use the right detergent to prevent the dishwasher from water leakage.

Using the wrong detergent can cause excessive siding and push water out of the dishwasher. 

Therefore, never use random detergent in your dishwasher; it could be a problem for water leakage. Always use detergents that are intended for dishwasher use only.

There are two types of detergent for dishwashers Liquid and powder capsule type. You can use any of these detergents in your dishwasher.

These detergents stay inside the unit instead of pooling onto the floor. 


Most new dishwasher including Samsung has this feature that automatically opens and closes the dispenser to minimize the risk of flooding and water build-up.

Most of the new dishwasher has features that can be controlled and operated by spring operated door latch to release the detergent automatically.

So, make sure to enable this feature from your dishwasher control panel. If the water is still leaking, there should be another issue behind the leakage. 

Dishwasher is Unlevel

Samsung dishwasher can leak when the dishwasher is imbalanced or improperly installed. If you have recently bought a dishwasher, you are likely to have this issue.

When the dishwasher is not installed correctly inside the cabinet, it can create a leakage issue. 

In this situation, one side of the dishwasher will have more water, and on the opposite side, there will be no water or significantly less water.

This could cause water leakage in the dishwasher. Dishwasher alignment can be checked using Spirit level. This will help you find if your dishwasher is perfectly aligned or not. 


The solution to this problem is to check if the dishwasher is perfectly aligned or not. If the dishwasher is misbalanced or aligned, there is a high chance of leakage.

So, remove the dishwasher from the cabinet and see if there is an obstacle, then make sure to remove it.

Besides this, you can also use shims under the dishwasher to align the dishwasher to its perfect level.  

Faulty Float Switch

A float switch is a failsafe device located under the bottom of the dishwasher tub, which measures the water level in the dishwasher.

This switch measures the water level in the machine and makes sure that the water is not overloaded inside the dishwasher.

Sometimes the float switch may stop working and send the wrong signal to the dishwasher, causing the dishwasher to leak.

It sends a signal to turn off the water supply inside the dishwasher when it is working correctly.

This float switch is found inside the bottom of the dishwasher tub. You can inspect the switch by removing the kickplate panel near the dishwasher door. 


The first and foremost step is to find out if the switch is working correctly or not. If it is not, you need to change that from your dishwasher.

Then, it can stop water from leaking. So, here is the stepwise instruction to fix the issue in your dishwasher.

  1. First of all, close the dishwasher power.
  2. Now open the dishwasher door; after this, remove the kick plate located near the dishwasher door. 
  3. Depending upon the dishwasher model, it requires a screw to remove the plate. Unscrew all the screws from there, and you can easily access the kick plate after this. 
  4. Now you can access the float switch just below the float assembly. The float switch is mainly located on the left or right side of the dishwasher. 
  5. Remove the float switch from the dishwasher and replace it with a new switch. 

Dishwasher is overloaded

Overloading of dishes is another reason that can cause the dishwasher to leak. If you load more dishes than recommended by the dishwasher, then there is a high chance of water leak.

The water inside the dishwasher can get diverted, creating a problem of leakage. 

Moreover, the dishes also won’t be cleaned properly as water cannot circulate through all the dishes.

Therefore, if you use your dishwasher with more loads and dishes, consider putting fewer dishes in your dishwasher.
