E15 Error Code On Bosch Dishwasher

The E15 error code on your Bosch dishwasher is telling you there is a risk of too much water. The E15 error code will show and drain out the water to prevent water from leaking out.

E15 error code Bosch dishwasher

The E15 error code on Bosch dishwashers indicates a problem with the water supply or water management system. It is also known as the “AquaStop error” or “water leakage error.” This error occurs when the dishwasher detects water leaking into the base or the presence of excess water within the unit, activating the AquaStop safety feature to prevent flooding or damage.

What to do to fix the error:

  1. Check the water hoses.
  2. Float switch causes error.
  3. Filter is clogged.
  4. Angle the dishwasher.
  5. Door seal issue.
  6. Check the sump.

Inspect the Hoses

Your dishwasher’s hoses play a critical role in supplying and draining water. Over time, these hoses can become damaged or worn, leading to leaks and triggering the E15 error.

Inspect your dishwasher’s hoses for any visible signs of damage or wear. If you discover any issues, replace the hoses with new ones.

Check and replace damaged hoses:

  1. Turn off the dishwasher and disconnect it from the power supply and water connection.
  2. Locate the inlet hose and drain hose. The inlet hose connects the dishwasher to the water supply, and the drain hose carries the wastewater out of the dishwasher.
  3. Check the hoses for any visible signs of damage, such as cracks, tears, bulges, or kinks.
  4. Check the connections of both the hoses to ensure they are secure and not loose.
  5. Clean the drain hose by running water through the hose into a bucket using the dishwasher “drain” program.
  6. Check any water lines or hoses inside the dishwasher that could be leaking and causing the error.

Stuck Float Switch

This safety component keeps an eye on the amount of water in your dishwasher to ensure it remains at a safe level. If it becomes stuck in a raised position or is faulty, the dishwasher may falsely detect a water leak, causing the E15 code to appear.

To clean and reset the float switch:

  1. Disconnect your dishwasher from its power source and take off the bottom plate to access the float switch.
  2. Clean the float switch and its surrounding area to ensure it can move freely.
  3. Gently push the float switch down, then release it to ensure it is not stuck.
  4. Put the dishwasher back together and determine if the E15 issue has been solved.

Clean the Clogged Filter

If your dishwasher’s filters become blocked or clogged, water may not drain correctly, leading to excess water within the unit and triggering the E15 error.

Regularly cleaning your dishwasher’s filters can help prevent blockages that cause the E15 error.

To clean the filter on a Bosch dishwasher:

  1. Locate the filter system at the bottom of the dishwasher.
  2. Remove any large food particles or debris.
  3. Use a soft brush or cloth to clean the filter housing area.
  4. Clean the filter with warm water and soap.
  5. Rinse the filter thoroughly and install it back into the dishwasher.

Angle the Dishwasher

Simply angling or tilting your dishwasher can help to remove the error code and drain your dishwasher.

  1. Turn off water and power to your dishwasher.
  2. Slide the dishwasher out.
  3. Angle it to a 35-45 degree angle.
  4. Secure it in place and leave it set awhile

This may reset the error code and allow the dishwasher to drain properly. Angling it allows water to move away from the safety switch and reset it.

Check the Door Seal

The door seal is responsible for keeping water within the dishwasher during operation. A worn or damaged door seal can cause water to leak out, resulting in the E15 error.

If you find that your dishwasher’s door seal is damaged or worn, replace it with a new one to prevent water leakage.

Inspect the Sump

The sump is the part of your dishwasher that collects water during the wash cycle. If the sump is cracked or leaking, water can seep into the base, prompting the E15 error.

If you suspect a leaking or cracked sump, you may need to have it professionally inspected and repaired to resolve the E15 error.

The E15 error code can be displayed on various Bosch dishwasher model numbers, as it is a common error code related to the leakage protection system present in Bosch dishwashers. But can display on any Bosch dishwasher that has a display panel. They include the 500, 800, and Benchmark series.
