Symptom / Description

FAULT

Bosch Serie 4 / Serie 6 / Serie 8 ActiveWater & PerfectDry Zeolith: Scale build-up on heating element E10; reduced heat transfer efficiency and slow water temperature rise.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Bosch dishwashers: Heavy lime scale deposit insulating heating element surface, depleted softening salt in ion exchanger, or hard water setting wrong.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Refill salt container with coarse dishwasher salt. Run intensive descaling cycle with citric acid descaler. Check hardness setting according to local water supply. 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 E10

FAQ TREE

What does error code E10 mean on a Bosch appliance?

Bosch error code E10 indicates: Bosch Serie 4 / Serie 6 / Serie 8 ActiveWater & PerfectDry Zeolith: Scale build-up on heating element E10; reduced heat transfer efficiency and slow water temperature rise..

What is the root cause of Bosch error code E10?

The primary root cause for Bosch code E10 is: On Bosch dishwashers: Heavy lime scale deposit insulating heating element surface, depleted softening salt in ion exchanger, or hard water setting wrong..

How do I fix or resolve Bosch error code E10?

To resolve error code E10: Refill salt container with coarse dishwasher salt. Run intensive descaling cycle with citric acid descaler. Check hardness setting according to local water supply. 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 E10 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Bosch code E10 persists, the physical component causing On Bosch dishwashers: Heavy lime scale deposit insulating heating element surface, depleted softening salt in ion exchanger, or hard water setting wrong. must be inspected or replaced.

How do I test electrical resistance for Bosch code E10 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 E10?

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.
