How to Fix E24 Bosch Dishwasher Errors: A Comprehensive Guide

In the world of modern convenience, dishwashers have become an indispensable part of our daily lives. However, as with any appliance, they can sometimes throw a curveball in the form of an error code. One such code that often leaves Bosch dishwasher owners perplexed is the dreaded E24 error. Fear not! In this comprehensive guide, we will unravel the mystery of the E24 error and provide you with step-by-step solutions to fix it.

Understanding the E24 Error

What is the E24 Error?

The E24 error code in Bosch dishwashers is an indication of a draining issue. It means that your dishwasher is unable to drain the water properly. This can lead to standing water in the bottom of your dishwasher, incomplete cycles, and ultimately, dirty dishes.

Causes of the E24 Error

Several factors can trigger the E24 error:

1. Clogged Filter

A clogged filter is one of the most common causes of this error. Over time, debris, food particles, and grease can accumulate in the filter, obstructing the drainage process.

2. Blocked Drain Hose

If the drain hose is bent or blocked, it can prevent water from draining effectively, triggering the E24 error.

3. Faulty Drain Pump

A malfunctioning drain pump may not be efficiently removing water from the dishwasher, leading to drainage problems.

4. Plumbing Issues

Sometimes, the issue may not be with your dishwasher but with your plumbing system. A clogged sink drain or air gap can also cause drainage problems.

How to Fix the E24 Error

Now that we’ve identified the possible causes let’s delve into the solutions:

1. Clean the Filter

Start by turning off the dishwasher and removing the bottom rack. Locate the filter assembly at the bottom and carefully remove it. Clean the filter under running water, removing all debris and residue. Once cleaned, reassemble the filter.

2. Inspect the Drain Hose

Check the drain hose for any kinks, bends, or blockages. If you find any, straighten the hose and remove obstructions. Ensure that the hose is correctly connected to your plumbing system.

3. Test the Drain Pump

To test the drain pump, you’ll need to access it beneath the dishwasher. Disconnect the power supply and remove the kickplate. Manually rotate the impeller of the drain pump to ensure it moves freely. If it’s stuck or doesn’t move, consider replacing the pump.

4. Check Plumbing

Inspect your sink’s drain and air gap to ensure they are not clogged. Run water through them to check for blockages. If needed, clean or unclog these components.


The E24 error code on your Bosch dishwasher may seem daunting, but with the right knowledge, you can troubleshoot and fix it yourself. By following the steps outlined in this guide, you can ensure your dishwasher runs smoothly, leaving you with sparkling clean dishes every time.

How often should I clean the filter in my Bosch dishwasher?
