E17 — Water Inflow / Overfill Fault

Per Bosch's official US error-code page, E16 and E17 are grouped together: there is an issue with water flowing into the dishwasher or the filling system, and water may not be able to enter the dishwasher. Bosch's instructions point at checking the inlet hose for the fault.

How to fix it

  1. Check household water pressure; if it is very high, a pressure-limiting measure may be needed.
  2. Inspect the water inlet valve — it should close fully and not weep when off; replace if it leaks through.
  3. Check the float in the tub base for free movement and the flow sensor for proper operation.
  4. Clear any overfill water and run a cycle to confirm.

Why it happens

Typical signs: E17 shown on the display · Dishwasher stops during or after filling · Possible extra water in the tub

  • High household water-supply pressure Pressure above the dishwasher’s expected range can overfill it. Bosch specifies a supply-pressure range — very high pressure can trip E16/E17.
  • Water inlet valve not shutting off A stuck or leaking inlet valve keeps admitting water.
  • Float switch stuck or flow sensor fault A stuck float or a miscounting flow sensor can report an overfill.
