What Does Error E15 Mean?

The Neff Dishwasher E15 error code indicates a water leakage detection issue. This activation of the flood protection system occurs when water is detected in the base of the appliance, often due to a leak or accumulation. You may notice a continuous beeping sound and the cycle will interrupt. It's crucial to address this as it prevents potential flooding and damage.

Common Symptoms:

  • Dishwasher displays E15 error and usually interrupts cycle
  • Possible continuous or unusual drain pump activity due to flood sensor activation
  • Presence of water in the base tray when inspected
  • Error reappears after reset if underlying leak not resolved

Possible Causes

  • Water accumulation in the base activating the anti‑flood/flood protection system (high)
  • Internal leak from damaged or loose components (e.g., seals, hoses, pump gasket) (medium)
