Symptom / Description

FAULT

Iberna IDI / Standard Wash System Dishwasher: Turbidity optical sensor fault E9; infrared soil sensing system fails calibration during pre-wash evaluation.

TELEMETRY // LIVESIG: FAULT_DETECTED

Root Cause

ROOT CAUSE

On Iberna dishwashers featuring Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Grease film coating optical lenses in sump, disconnected sensor plug, or burned infrared transmitter LED.

CIRCUIT // SUBSYSTEMLOGIC: ROOT_ISOLATED

Repair Instructions

UNLOCKED

1Clean optical turbidity sensor prism inside sump using soft cloth and degreaser. Check 5V DC power supply on sensor connector pins. Press and hold Start button for 5 seconds until buzzer sounds, close door to allow pump-out cycle to complete, then switch off.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Disconnect electrical power before touching solenoid valve coils or Aquastop connectors.
!Firmly shut off the domc water supply tap before unscrewing the inlet hose fitting.
!Check safety base drip tray for accumulated water triggering the anti-flood polystyrene float switch.

3. Preliminary Mechanical & Visual Checks

Remove and clean sediment and sand particles from the 3/4" inlet hose metal mesh filter.
Verify domestic dynamic water pressure is between 1.0 and 10.0 bar (0.1 to 1.0 MPa).
Inspect outer Aquastop hose jacket for expansion, pinch damage, or internal leak reservoir triggering.

Frequently Asked Questions: Iberna E9

FAQ TREE

What does error code E9 mean on a Iberna appliance?

Iberna error code E9 indicates: Iberna IDI / Standard Wash System Dishwasher: Turbidity optical sensor fault E9; infrared soil sensing system fails calibration during pre-wash evaluation..

What is the root cause of Iberna error code E9?

The primary root cause for Iberna code E9 is: On Iberna dishwashers featuring Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Grease film coating optical lenses in sump, disconnected sensor plug, or burned infrared transmitter LED..

How do I fix or resolve Iberna error code E9?

To resolve error code E9: Clean optical turbidity sensor prism inside sump using soft cloth and degreaser. Check 5V DC power supply on sensor connector pins. Press and hold Start button for 5 seconds until buzzer sounds, close door to allow pump-out cycle to complete, then switch off.

Is it safe to clear Iberna error code E9 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Iberna code E9 persists, the physical component causing On Iberna dishwashers featuring Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Grease film coating optical lenses in sump, disconnected sensor plug, or burned infrared transmitter LED. must be inspected or replaced.

How do I test electrical resistance for Iberna code E9 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Solenoid Valve Coil / Aquastop Pneumatic Valve across Across coil spade terminals (disconnect harness first). Expected nominal reading is 3.5kΩ–4.5kΩ (Standard 230V) / 2.0kΩ–4.2kΩ (Aquastop). Tolerance: ±10%. Open circuit (OL) indicates burned solenoid coil. Flowmeter turbine reed switch pulses on flow..

What safety protocol must be followed before servicing Iberna code E9?

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.
