Bosch Dishwasher Error E15: Leak Detected

The Logic Verdict

My Take: First try the easy fix in the video. People often tilt the machine back 45 degrees to drain the water and reset the sensor (but this doesn’t fix the leak). If the error comes back, you have a real leak that needs to be tracked down—often it’s the sump seal or a loose hose.

What It Means

The E15 code stands for Water in Base. The safety float switch in the bottom pan has tripped, activating the drain pump continuously.

Common Causes

1. Leaking pump seal (Sump).
2. Loose hose connection.
3. Oversudsing (wrong soap).
4. Water inlet valve leak.

Step-by-Step Fix

1. Tilt Method: Pull dishwasher out, tilt it back 45 degrees to drain water from the base pan. (Have a towel ready).
2. Reset: This clears the error, but you must find the leak if it returns.
3. Inspect: Run a cycle with the side panel off and watch for drips.
