The error E24 on the Bosch dishwasher alerts you about the drainage problem with the device due to a filter blockage.

There are some reasons that the filter may have been blocked and the reason is the key to finding out exactly what you should do to take care of the problem.

Here is why your filter might have been blocked.

  • The drain hose of the dishwasher is blocked

We have mentioned all the reasons above that can be a factor in the error E24 on your dishwasher.

Now we will discuss each problem in detail and suggest fixes for the same so that you can apply a fix according to your specific problem.

Fix 1: The drain hose is blocked

As we are already aware that the problem is with the drainage compartment of the dishwasher, therefore, the energy should be focused on finding out what part is blocked so that it may be cleaned and cleared out.

The first component that you should check is the drain hose. If the problem is not found here, then you can move to the other compartments to check.

The drain hose is the compartment that can get easily blocked because it is a pipe with a relatively narrow cross-section. Gunk can easily accumulate here and obstruct the flow of water from the dishwasher.

Disconnect the drain hose and inspect it for accumulation of debris. If it is found blocked, clean it thoroughly before reattaching it. If this was the only part with blockage, you will see that your problem has been solved.

Fix 2: You have not cleaned the filter in a long time

As everyone is aware, filters cannot go on with their functions if they are not cleaned regularly. There is a set time interval mentioned in the user manual that the filter remains efficient without a clean.

In Bosch Dishwashers, it is a good practice to clean the filter every three months. It is even more optimal if you clean the filter once every month. 

Reading all this, if you are thinking about your last filter cleaning which was never, you might have figured out the problem.

Go and clean the filter as soon as possible.

Fix 3: You have installed a new garbage disposal

Whenever you install a new garbage disposal, you have to optimize and adjust the dishwasher accordingly. You cannot think that the dishwasher will get accustomed to the changed system without any intervention.

In some cases, it might but why even take the chance.

Make sure that the Knockout Plug is removed whenever new garbage disposal is installed. This will make sure that the dishwasher does not experience any issues with drainage.

Fix 4: The inlet hose has a kink

We have mentioned above that the inlet hose has a small cross-section for the water from the dishwasher to flow. Sometimes, when we have carelessly installed the dishwasher in a cramped place, then the hose connected to the dishwasher may get twisted.

This can cause a kink in the hose and the water will not pass through. If you notice a kink in the inlet hose, remove it and then place the dishwasher in a position where the inlet hose does not twist again.

Fix 5: The Siphon connection is not sealed

The siphon is an important component of the Bosch Dishwasher. The connection to the siphon should be secure and monitored closely at regular intervals.

If the connection of the siphon is loose, the drainage of the dishwasher will be seriously impacted and you will frequently see an error message on the dishwasher until the connection is sealed again.

Fix 6: The pump cover of the dishwasher is loose

The pump cover of the dishwasher is one of the most overlooked parts when people test the functioning of the dishwasher.

The cover should be secure at all times just like the siphon and if it is loose, it will not allow the correct flow of water.

Hence, the drainage problem.

Make sure that the pump cover of the dishwasher is not loose. You can find the care instructions for the same on the user manual of the dishwasher.

Fix 7: Contact the support

The Bosch Dishwasher might be a cheaper option in the market but it still costs a significant amount of money. If you have tried every solution possible but you cannot get rid of the error on the system, then you need to contact the support helpline.

They will send in a technician with the proper tools to take care of the dishwasher. If the device is far beyond repair in some unfortunate cases, they might even provide you with a replacement piece depending on the warranty.

Here is where you can contact the support team.


Generally, Bosch dishwashers are very efficient and they do not need much maintenance. When they do need some serious maintenance though, they will alert you with different error codes.

In this blog, we have addressed how to solve the error E24 on the dishwasher. The solutions are taken from the official support page of Bosch Dishwasher support so you can make sure that these fixes are genuine and helpful.
