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.
