Repair Instructions

UNLOCKED

1Disconnect mains power. Sponge out water from bottom collection tray. Inspect sump gasket, pump hose clamps, and tub seams with dry paper. Test anti-flood microswitch continuity with a multimeter. Press and hold Start/Cancel button for 6 seconds until all cycle lights extinguish, then switch off mains toggle switch.

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.

What does error code E4 mean on a Rosieres appliance?

Rosieres error code E4 indicates: Rosières RLI / RDS Grande Capacité Built-in Dishwasher: Anti-flood leak protection triggered E4; float switch in the bottom chassis pan rises and engages emergency drain..

What is the root cause of Rosieres error code E4?

The primary root cause for Rosieres code E4 is: On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Leaking sump seal, split recirculation pump casing, door perimeter gasket wear, or cracked fill hose connection..

How do I fix or resolve Rosieres error code E4?

To resolve error code E4: Disconnect mains power. Sponge out water from bottom collection tray. Inspect sump gasket, pump hose clamps, and tub seams with dry paper. Test anti-flood microswitch continuity with a multimeter. Press and hold Start/Cancel button for 6 seconds until all cycle lights extinguish, then switch off mains toggle switch.

Is it safe to clear Rosieres error code E4 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosieres code E4 persists, the physical component causing On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Leaking sump seal, split recirculation pump casing, door perimeter gasket wear, or cracked fill hose connection. must be inspected or replaced.

How do I test electrical resistance for Rosieres code E4 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 Rosieres code E4?

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.
