E15 Bosch dishwasher E15 error
High severity
What it means
The E15 error means the machine has detected a water leak (Aquastop) and stopped for safety.
Likely causes
Water pooled in the base tray under the machine, a leaking hose connection, or a faulty Aquastop valve.
Safe steps you can try
Unplug the machine, check the base tray underneath and clear any standing water. Tighten the water hose connections firmly.
When to call a technician
If the leak source cannot be found or the error repeats, the Aquastop system needs diagnosis by a technician — this prevents serious water damage.
