E17 Moderate Easy DIY

Bosch Dishwasher E17 — Fill too fast / high inlet flow

Bosch Dishwasher · Error code E17

What E17 Means

The flow meter recorded the fill volume faster than expected. Either supply pressure is high or the meter is miscounting.

Symptoms

  • Cycle pauses just after fill
  • E17 logged but cycle sometimes completes
  • Wash performance OK otherwise

Common Causes

1
High house water pressure

Above 120 psi - over the Bosch spec.

2
Flow meter miscount

Impeller pulsing erratically (early failure).

3
Failed pressure reducer

House PRV failed open, supplying full street pressure.

4
Air slug in supply

Air pocket after plumbing work spinning the impeller without water flow.

How to Fix It

  1. Check house water pressure at a hose bib (should be 40-80 psi typical).
  2. Install or service the house pressure-reducing valve if reading above 80 psi.
  3. Run several Rinse cycles to bleed any air from the supply.
  4. If error persists with normal pressure, replace the AquaStop / flow meter assembly.
