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
How to Fix Error E15

- If any water is visible, dry it with towels or a wet/dry vacuum.
- Inspect around the door seal and visible hoses for signs of leaks or loose connections.
Technician Only Professional inspection for leak and safety system trigger

- Check integrity of door seals, inlet valve, drain hoses, and any internal hoses for leakage.
- Test safety/flood sensor and replace if defective.
- Repair any identified leaks and ensure the base pan is dry before clearing the error.
Parts needed: Leak/flood sensor or float switch (if present), Door/gasket seals, Hoses and clamps
