Expert Advice on Troubleshooting Bosch Dishwasher Error Codes

Bosch dishwashers are known for their reliability and efficiency in the kitchen. However, like any other appliance, they may encounter issues from time to time. One common problem that many Bosch dishwasher owners face is error codes. These codes are designed to help you diagnose and fix the issue quickly so you can get back to enjoying clean dishes. In this article, we will provide expert advice on troubleshooting Bosch dishwasher error codes.

Understanding Bosch Dishwasher Error Codes

Bosch dishwashers are equipped with an advanced system that detects malfunctions and displays error codes on the control panel. These error codes consist of a combination of letters and numbers that correspond to specific problems. By understanding what these codes mean, you can take the necessary steps to resolve the issue yourself or communicate it effectively to a professional technician.

Common Bosch Dishwasher Error Codes

E15: This error code indicates a leakage in your dishwasher’s base, triggering a flood sensor. To troubleshoot this issue, first, disconnect the power supply to prevent any electrical damage. Then check for any visible signs of leakage around your dishwasher’s base, including hoses and connections. If you cannot identify the source of the leak, it is recommended to contact a professional technician for further investigation.

E24: This code signifies a drainage problem in your dishwasher. Start by checking if there is any blockage or clog in your dishwasher’s drain hose or filter system. Clean out any debris or foreign objects that might be obstructing proper drainage. If everything seems clear but the error persists, it could be an issue with the drain pump itself. In such cases, it is best to seek professional help.

E01: The E01 code indicates an issue with your dishwasher’s heating element or temperature sensor. First, make sure there are no loose connections or damaged wires around these components. If everything looks fine, it may be necessary to replace the faulty part. Contact a professional technician or refer to your dishwasher’s user manual for guidance on replacing these components.

Troubleshooting Bosch Dishwasher Error Codes

Resetting Your Dishwasher: In some cases, a simple reset can resolve minor issues and clear error codes. To reset your Bosch dishwasher, turn off the power supply and unplug it from the socket. Wait for approximately 10 minutes before plugging it back in and turning the power supply on again. This action will allow the dishwasher’s system to reboot, potentially clearing any temporary errors.

Checking Water Supply: Ensure that your dishwasher is receiving an adequate water supply. Check that the water inlet valve is fully open and not blocked by any debris. Also, inspect the water inlet hose for any kinks or clogs that might restrict water flow into the appliance.

Cleaning Filters and Spray Arms: Regularly cleaning your dishwasher’s filters and spray arms can prevent clogs and improve its overall performance. Remove any accumulated food particles or debris from the filters and clean them under running water. Similarly, detach the spray arms and rinse them thoroughly to remove any blockages.

When to Call a Professional

While some Bosch dishwasher error codes can be resolved with basic troubleshooting steps, there are instances where professional assistance is necessary. If you are unsure about how to proceed or if you have attempted several troubleshooting methods without success, it is best to consult a qualified technician.

Professional technicians have the knowledge, experience, and specialized tools required to diagnose complex issues accurately. They can also provide you with guidance on whether a repair or replacement is more cost-effective in case of major component failures.


Bosch dishwashers are designed to make our lives easier in the kitchen, but occasionally error codes may pop up indicating underlying issues. Understanding common error codes like E15, E24, and E01 allows you to troubleshoot the problem effectively. Basic troubleshooting steps such as resetting your dishwasher, checking water supply, and cleaning filters and spray arms can often resolve minor issues. However, if the problem persists or if you are unsure about how to proceed, it is always best to seek professional assistance. By following these expert tips on troubleshooting Bosch dishwasher error codes, you can ensure that your dishwasher continues to work efficiently for years to come.
