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.

Common Symptoms:

  • 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)
