Bosch Dishwasher: AquaStop triggered

Professional Repair Guide

What is this symptom?

Is your Bosch dishwasher showing an AquaStop error? This indicates a leak detection issue, causing the appliance to shut off water supply. Commonly, this happens when water collects in the base pan, triggering the internal float switch. You may also see error codes or indicator lights on the control panel. Resolving this issue can prevent further damage and restore functionality.

Urgency: Medium
