Symptom / Description

FAULT

Bosch Serie 4 / Serie 6 / Serie 8 ActiveWater & PerfectDry Zeolith: High water inlet pressure / overflow risk E17; flow rate into heat exchanger exceeds maximum allowable speed.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Bosch dishwashers: Household water mains pressure > 10 bar (1.0 MPa), water hammer effect, or flow restrictor missing from inlet hose.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED
1Partially close household supply tap to throttle water intake. Install a water pressure regulator (set to 2.5–4.0 bar) to protect the internal matrix. Hold Start/Reset key for 3 seconds until '0:01' appears, close door, allow 60s for drain completion, then power off.

1. Pre-Intervention Electrical Safety Protocols
  • !Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
  • !Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
  • !Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.
3. Preliminary Mechanical & Visual Checks
  • Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
  • Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
  • Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.

Frequently Asked Questions: Bosch E17

FAQ TREE
What does error code E17 mean on a Bosch appliance?

Bosch error code E17 indicates: Bosch Serie 4 / Serie 6 / Serie 8 ActiveWater & PerfectDry Zeolith: High water inlet pressure / overflow risk E17; flow rate into heat exchanger exceeds maximum allowable speed..

What is the root cause of Bosch error code E17?

The primary root cause for Bosch code E17 is: On Bosch dishwashers: Household water mains pressure > 10 bar (1.0 MPa), water hammer effect, or flow restrictor missing from inlet hose..

How do I fix or resolve Bosch error code E17?

To resolve error code E17: Partially close household supply tap to throttle water intake. Install a water pressure regulator (set to 2.5–4.0 bar) to protect the internal matrix. Hold Start/Reset key for 3 seconds until '0:01' appears, close door, allow 60s for drain completion, then power off.

Is it safe to clear Bosch error code E17 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E17 persists, the physical component causing On Bosch dishwashers: Household water mains pressure > 10 bar (1.0 MPa), water hammer effect, or flow restrictor missing from inlet hose. must be inspected or replaced.

How do I test electrical resistance for Bosch code E17 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

What safety protocol must be followed before servicing Bosch code E17?

Standard electrical safety protocol: 1. Disconnect 230V mains power before opening panels. 2. Verify zero voltage at test points. 3. Allow hot water or heating elements to cool below 30°C before handling.
