Rosieres E9

Q: What does error code E9 mean on a Rosières appliance?

Rosières error code E9 indicates: Rosières RLI / RDS Grande Capacité Built-in Dishwasher: Turbidity optical sensor fault E9; infrared soil sensing system fails calibration during pre-wash evaluation..

Q: What is the root cause of Rosières error code E9?

The primary root cause for Rosières code E9 is: On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Grease film coating optical lenses in sump, disconnected sensor plug, or burned infrared transmitter LED..

Q: How do I fix or resolve Rosières 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/Cancel button for 6 seconds until all cycle lights extinguish, then switch off mains toggle switch.

Q: Is it safe to clear Rosières error code E9 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosières code E9 persists, the physical component causing On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Grease film coating optical lenses in sump, disconnected sensor plug, or burned infrared transmitter LED. must be inspected or replaced.

Q: How do I test electrical resistance for Rosières code E9 using a multimeter?

Set a digital multimeter to ohms (Ω). Disconnect power and test Protective Earth Bonding & Incoming Mains Voltage across Between unpainted chassis metal and mains plug earth pin; incoming terminal block L-N. Expected nominal reading is Earth Ground Continuity: <0.1Ω (Chassis metal to mains plug earth pin). Mains: 230V AC ±10%.. Tolerance: Protective conductor impedance must remain <0.1Ω. Line voltage 207V–253V AC under load..

Q: What safety protocol must be followed before servicing Rosières 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.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Disconnect electrical mains plug or trip dedicated circuit breaker before servicing.
!Wait at least 5 minutes before opening any casing panels to reset volatile microcontrollers and bleed residual charges.
!Operate in a dry workshop environment; never bypass internal electrical thermal cutouts.

3. Preliminary Mechanical & Visual Checks

Check appliance leveling with a spirit level; adjust threaded leveling feet for perfect stability.
Check door and lid perimeter rubber gaskets for tears, gaps, or foreign object obstruction.
Inspect shock absorbers, suspension springs, and rubber dampers for mechanical fatigue or excessive play.
