Troubleshooting the Bosch e24 Error: A Complete Guide

Share This Post:

Today dishwashers are one of the most essential pieces of kitchen equipment, but when they malfunction or display error codes, like the Bosch e24 error, it can cause great concern and frustration. But did you know that modern technology has embedded error codes to help you pinpoint the exact source of the problem and then quickly troubleshoot it yourself?

We’ll walk you through troubleshooting the Bosch e24 error and provide a step-by-step guide to rectify the problem.

What is a Bosch e24 Error?

When you see the Bosch e24 error code displayed on your dishwasher, it means your dishwasher is not draining properly. While Bosch is a reliable, high-quality dishwasher manufacturer, their products are still susceptible to normal wear and tear after using them over time. 

When this happens, Bosch dishwashers alert users to any issues. One way of doing this is by displaying the Bosch e24 error.

This occurs primarily due to a clogged filter or when the drain filter is blocked by something. The Bosch e24 error is fairly common and requires simple cleaning of the filter, drain hose, and drain pump. It can easily be fixed at home, but if the problem persists, then it’s best to call in the experts. 

What Causes a Bosch e24 Error?

There are many reasons why your dishwasher may not drain correctly and give a Bosch e24 error code, but some of the most likely causes include the following:

  • A blocked drain hose.
  • A clogged dishwasher filter that requires cleaning
  • When you may have forgotten to remove the “knockout plug” after installing a new garbage disposal
  • You may have forgotten to reset the dishwasher in the manner the manual suggested after fixing the problem.
  • When there’s something wrong with the sealing of the siphon connection
  •  If the pump cover under the filter is loose
  • If the inlet hose is bent, twisted, or damaged

Troubleshooting the Bosch E24 Error Code: A Step-by-Step Guide

Step 1: Ensure it isn’t a control panel glitch

Glitches in the dishwasher’s control panel often result in an incorrect error code, including the Bosch e24 error. These are usually one-time errors and can be fixed by disconnecting the dishwasher from the power supply for a few minutes and plugging it back in. If the issue was just a glitch in the control panel, then unplugging it should resolve the problem.

An alternative route to determining whether it’s a control panel glitch is to press the start button and hold it for a few seconds. This will reset everything, and empty the dishwasher. If the water doesn’t begin to drain, then chances are that there’s something else going on with your dishwasher’s drainage and needs fixing.

Step 2: Inspect the hoses

One of the most common reasons you get a Bosch e24 error code on your dishwasher is that the hoses connected to it are either bent or twisted. When this happens, water is restricted from entering or leaving the dishwasher. 

If you are sure that the error isn’t from a control panel glitch, check the hoses and ensure that they are not kinked. 

Step 3: Clean clogged filters and the sump

Cleaning out the dishwasher’s sump and clogged filter is often all that is required to fix a Bosch e24 error. The filter can be found in the midsection at the base of the dishwasher. 

To access it, remove the bottom dish rack and spray the arm first. Remove the filter by turning it counterclockwise and wash it with soap and water to remove any blockages or particles clogging it.

Also, check the sump to ensure there is nothing stuck at the base, which may be restricting the drainage.

Step 4: Ensure that the pump and its cover are intact

If the problem persists and you continue to get a Bosch e24 error, it is best to look at the drain pump and its cover. These can be easily accessed, cleaned, and unclogged by simply removing the cover around the filter. 

Once you find the pump, check whether the cover is tightly secured or loose. Often, a loose pump cover can also cause a Bosch e24 error.

After ensuring that the cover is properly intact, inspect the pump again and watch out for any blockages. Also, check the tab beside it and remove it to access the smaller pump. Once you remove the cover, the pump impeller should be visible. 

Check if there are any blockages near the small cap and remove them. If you feel that the impeller isn’t turning or jammed, chances are that your Bosch dishwasher drain pump is defective and needs replacement.

Clean out the pump and its surrounding area. Now put the cover and the filter back. Test again to check if the problem is resolved or not. If the problem persists, then there might be something wrong with the drain hose.

Step 5: Inspect the drain hose

If you have checked all of the areas mentioned above and are still getting a Bosch e24 error, then it’s best to inspect the drain pipe or the hose. These are usually connected to the drain pipes and are sometimes attached to an air gap, an S-trap, or a garbage disposal.

Once you have located the drain hose, check underneath the sink to see if it is clogged or not. You first might have to remove the clamp on top of the hose and disconnect it from your sink. Once done, remove any dust or gunk that might be responsible for the blockage. Put everything back together and test to see if the problem persists.

Step 6: Check for blockages in the air gaps and garbage disposal

While the steps mentioned above usually help fix the Bosch e24 error code, sometimes a blockage in the S-trap may also occur and can end up restricting the water drainage from your dishwasher. 

To ensure this isn’t the case with your dishwasher, try to remove the cover on the air gaps and look for any potential air blockages. Many households face this problem after installing a new dishwasher. Technicians usually don’t leave the plug on the garbage disposal but forgetting to pull the plug can cause your dishwasher to malfunction. 


From learning to make cabinets at home to fixing a clogged dishwasher at home, you can find many resources online to troubleshoot the problem and find a durable solution. 

The steps mentioned above are meant to do just that. Following them can help you fix the Bosch e24 error code in no time without worrying about paying hefty technician bills.
