What Does E24 Mean On A Bosch Dishwasher

In the world of modern appliances, Bosch has earned its reputation for manufacturing high-quality and innovative dishwashers. These machines are designed to make our lives easier by efficiently cleaning our dishes, leaving them spotless and ready for use. However, like any technology, Bosch dishwashers may encounter occasional hiccups, and one of the most common issues users face is the error code E24. In this article, we will delve into the meaning of E24 on a Bosch dishwasher, its causes, and how to troubleshoot it effectively.

Understanding the Basics: What is E24?

E24 is an error code that can appear on your Bosch dishwasher’s display panel. It serves as an indicator that there is a problem with the machine’s drainage system. Specifically, E24 suggests that the dishwasher is not draining properly, and this can lead to a variety of issues, including improper cleaning and potential damage to the appliance itself.

Common Causes of E24 Error

To address the E24 error on your Bosch dishwasher, it’s essential to understand the potential causes behind it. Here are some of the most common culprits:

1. Clogged Drain Hose

A clogged drain hose is a frequent cause of the E24 error. Over time, debris, food particles, and grease can accumulate in the hose, obstructing the water flow. This blockage prevents the dishwasher from draining efficiently.

2. Blocked Dishwasher Filter

The dishwasher filter is responsible for trapping food particles and preventing them from clogging the drainage system. If the filter becomes dirty or clogged, it can impede the draining process, triggering the E24 error.

3. Faulty Drain Pump

The drain pump is a crucial component of your dishwasher’s drainage system. If it malfunctions or fails, it will hinder the water from being pumped out of the machine properly, leading to the E24 error.

4. Incorrect Dishwasher Installation

Improper installation of your Bosch dishwasher can also be a contributing factor to the E24 error. If the drain hose is not correctly positioned or if there are kinks in it, drainage problems can occur.

Troubleshooting the E24 Error

Now that you know the potential causes of the E24 error, let’s explore some steps you can take to troubleshoot and resolve this issue:

1. Check the Drain Hose

Inspect the drain hose for any visible clogs or kinks. If you find any, remove them carefully. Ensure that the hose is properly connected to both the dishwasher and the sink drain.

2. Clean the Dishwasher Filter

Remove the dishwasher’s bottom rack and locate the filter assembly. Clean it thoroughly, removing any debris or food particles that may be obstructing the filter. Regularly cleaning the filter can prevent the recurrence of the E24 error.

3. Examine the Drain Pump

If you suspect a faulty drain pump, it’s advisable to consult a professional technician for a thorough inspection and repair. Replacing a malfunctioning drain pump may be necessary to resolve the E24 error.

4. Verify Installation

Double-check the dishwasher’s installation to ensure that the drain hose is correctly positioned and free from kinks or bends. Correcting any installation issues can help prevent future errors.


In conclusion, the E24 error code on your Bosch dishwasher is an indication of drainage problems that can affect its performance. By understanding the common causes and following the troubleshooting steps outlined in this article, you can resolve the issue and enjoy your dishwasher’s efficient operation once again.
