In this article, we will delve into the world of Bosch dishwasher errors, specifically focusing on the dreaded E15 error, and equip you with the knowledge and solutions to clear it without the need for professional help. So, grab a cup of coffee, sit back, and let’s get your Bosch dishwasher back in action!

Understanding the E15 Error Code

The E15 error code on your Bosch dishwasher signifies a leak in the base of the appliance. When the dishwasher detects water accumulating in the base, it triggers this error as a safety measure to prevent any potential flooding or electrical hazards. While this feature is undoubtedly useful for protecting your home, it can also lead to some false alarms, leaving you perplexed about what to do next.

Checking for Visible Leaks and Residual Water

Before diving into any complicated troubleshooting steps, let’s start by checking for visible leaks and clearing any residual water. First, make sure to turn off the dishwasher and disconnect it from the power source. Carefully pull the dishwasher out from its place and inspect the area underneath. Look for any signs of water leakage or pooling water. If you spot any visible leaks, it might indicate a damaged hose or a loose connection.

Next, open the dishwasher door and check the bottom of the tub. If there is water pooling at the base, it’s essential to clear it out before proceeding with any further steps. Use a sponge or a towel to absorb the water and dry out the area. This simple act of clearing residual water might just be enough to resolve the E15 error and get your dishwasher running again.

Ensuring Proper Door Closure

Sometimes, the E15 error may occur due to an improper door closure. A slightly open or misaligned door can cause water to leak out, triggering the error code. To ensure proper door closure, gently push the door until you hear a click, indicating that it’s securely shut. Additionally, inspect the door gasket for any visible damage or debris that might hinder a tight seal. If you notice any issues with the gasket, clean it thoroughly or consider replacing it if necessary.

Checking the Drain Hose

A clogged or kinked drain hose can also be a culprit behind the E15 error on your Bosch dishwasher. The drain hose is responsible for carrying the wastewater from the dishwasher to the drain or garbage disposal. Over time, food particles and debris can accumulate in the hose, obstructing the flow of water and leading to leaks.

To check the drain hose, start by turning off the dishwasher and unplugging it from the power source. Locate the drain hose, usually located at the back of the dishwasher, and detach it carefully. Check for any clogs or kinks by running water through the hose. If you find any blockages, gently remove them using a long, flexible brush or by flushing the hose with water. Once the hose is clear, reattach it securely, and run a test cycle to see if the error persists.

Inspecting the Float Switch

The float switch is a small component located at the base of the dishwasher, responsible for detecting the water level in the tub. If the float switch gets stuck or malfunctions, it may trigger the E15 error code even if there is no actual water leakage.

To inspect the float switch, you’ll need to remove the bottom panel of the dishwasher. Ensure the dishwasher is unplugged and safe to work on before proceeding. Once you have access to the bottom area, locate the float switch and check if it moves freely. Gently press it down and release it to see if it springs back up. If it doesn’t move or feels stuck, try cleaning the area around the float switch to remove any debris that might be causing the issue.

Resetting the Dishwasher

If you have gone through all the previous steps and the E15 error still persists, it might be time to try a simple reset. Resetting the dishwasher can sometimes clear out any temporary glitches or electronic malfunctions that might be causing the error code.

To reset your Bosch dishwasher, press and hold the “Start” button for about 3 to 5 seconds. This action should trigger a reset of the control panel. Once the reset is complete, try running a test cycle to see if the error has disappeared. If the E15 error is no longer displaying, congratulations, you have successfully cleared the error!

However, if the error code reappears, it’s best to consult the Bosch dishwasher manual or contact their customer support for further assistance. The issue might require professional diagnosis and repair.


Facing an E15 error on your Bosch dishwasher can be a frustrating experience, but armed with the troubleshooting steps provided in this article, you now have the confidence to tackle it on your own. Remember to check for visible leaks, ensure proper door closure, inspect the drain hose, and examine the float switch. And if all else fails, don’t hesitate to try a reset. By following these steps, you can often clear the E15 error and have your dishwasher working efficiently once again, saving you time, money, and the hassle of dealing with dirty dishes.
