What Does Error E17 Mean?

The Neff Dishwasher E17 error code signifies a water inlet valve problem, often resulting in the machine displaying no water fill or unusual sounds. This error typically occurs due to incorrect water level detection or water accumulation in the base tray, indicating a potential leak. If the dishwasher stops filling or believes the water level is incorrect, it could also mean continuous water flow into the machine. Addressing these issues promptly is crucial to prevent further complications.

  • No water enters or machine believes water level is incorrect
  • Potential triggering after a leak or water in the base tray
  • May be accompanied by continuous water flow into the machine

Possible Causes

  • Water inlet system fault (improper fill/level detection) (medium)
  • Internal overflow/flood‑tray float activation due to a leak (medium)
