What Does Error E15 Mean?
The E15 error on your Gaggenau dishwasher indicates a water leakage issue, triggered by the flood/float switch due to water accumulation in the base pan. This error often causes the dishwasher to stop mid-cycle, activates a continuous drain pump, and prevents water from filling. If you notice visible water under the machine, the error will persist until the base pan is completely dry.

- Dishwasher stops mid‑cycle
- Continuous drain pump running
- No filling of water
- Error persists until base pan is dry
- Possible visible water under machine
Possible Causes
- Water in the base pan triggering the flood sensor (activated float switch) (high)
