Bosch Dishwasher Error Code E15 – Meaning and Possible Fixes
Bosch Dishwasher Error Code E15
If your Bosch dishwasher displays Error Code E15, it usually means the appliance’s leak protection system has been activated. Bosch dishwashers include a safety feature designed to detect water inside the base of the appliance.
When water collects in the bottom tray, the dishwasher automatically stops the wash cycle and displays the E15 error code to prevent potential flooding.

What the E15 Error Means
The E15 error code indicates that the dishwasher has detected water in the base of the appliance. Bosch dishwashers use a float switch inside the base tray that triggers when water is present.
If the float switch activates, the dishwasher stops operating and may run the drain pump continuously to remove water from the system.
Common Reasons This Error Appears
Water leak inside the appliance
A small internal leak may allow water to collect in the base tray.
Excess detergent or foam
Using too much detergent can create excessive foam that may trigger the leak protection system.
Blocked filters or drainage issues
If water cannot drain properly, it may accumulate and trigger the safety system.
Temporary sensor trigger
Occasionally the sensor may activate after a spill or temporary overflow.
Safe Checks You Can Try
Before contacting a technician, there are a few safe checks you can try.
Check for visible water around the appliance
Inspect the floor around the dishwasher and look for any signs of leaking.
Clean the dishwasher filters
Remove the filters at the bottom of the dishwasher and rinse them under running water to ensure they are not blocked.
Reset the dishwasher
- Turn the dishwasher off using the power button.
- Switch off power at the wall socket or circuit breaker.
