What Does Error E15 Mean?

The E15 error on Blanco dishwashers indicates a water leakage detection issue, often triggered by the appliance's flood protection system. This may result in the dishwasher stopping mid-cycle or refusing to start, accompanied by a continuous beeping sound and flashing display lights. It is essential to investigate for any potential water accumulation beneath the unit, as this could signal a leak or fault in the system.

Common Symptoms:

  • Dishwasher stops mid‑cycle or refuses to start with E15 displayed (in other brands)
  • Potential water accumulation in base pan (reported in multiple generic sources)

Possible Causes

  • Leakage sensor failure
  • Damaged door seal
  • Clogged drain hose
