Bosch Dishwasher Troubleshooting E24

Bosch dishwashers are renowned for their efficiency and reliability. However, like any household appliance, they can encounter issues from time to time. One common problem that Bosch dishwasher owners may face is the error code E24. In this guide, we will delve into what the E24 error code signifies and provide step-by-step troubleshooting solutions to help you resolve this issue.

Understanding the E24 Error Code


Follow these systematic troubleshooting steps to identify and resolve the E24 error code on your Bosch dishwasher:

1. Check for Clogs in the Drainage System

  • Start by turning off the dishwasher and unplugging it from the power source to ensure your safety.
  • Access the dishwasher’s filter and remove any food particles or debris that might be obstructing the drainage system. The filter is usually located at the bottom of the dishwasher’s interior.
  • Inspect the drain pump, which is also located at the bottom of the dishwasher. Remove any debris or foreign objects that may be blocking the pump’s impeller.
  • Ensure that the drain hose is free from kinks or obstructions. Detach the hose and flush it with water to remove any potential blockages.

2. Examine the Sink Drain

  • Verify that your kitchen sink’s drain is not clogged or obstructed. A clogged sink drain can impede the dishwasher’s ability to drain water properly.

3. Check the Dishwasher’s Drain Hose

  • Inspect the dishwasher’s drain hose for damage or kinks. If you find any, replace the hose to ensure proper drainage.

4. Assess the Air Gap

  • If your dishwasher is connected to an air gap, make sure it is clean and free from debris. Cleaning the air gap can help prevent drainage issues.

5. Ensure Proper Installation

  • Check that the dishwasher is correctly installed and leveled. An improperly installed dishwasher may not drain effectively.

6. Test the Water Inlet

  • The E24 error code can also be triggered by a lack of water supply. Ensure that the water inlet valve is open and that there is sufficient water pressure.

7. Reset the Dishwasher

  • After performing the above checks and making necessary adjustments, reset the dishwasher by turning it off and then back on. This may clear the error code if the issue has been resolved.

8. Consult the Owner’s Manual

  • If you are unable to resolve the E24 error code after following these troubleshooting steps, consult your Bosch dishwasher’s owner’s manual for additional guidance and information specific to your model.

9. Contact Customer Support or a Technician

  • If the issue persists and you cannot identify the problem, it’s advisable to contact Bosch customer support or a certified technician for professional assistance. They can diagnose and repair more complex issues with your dishwasher.
