Rosieres E7

Rosieres error code E7 indicates: Rosières RLI / RDS Grande Capacité Built-in Dishwasher: Wash circulation pump failure E7; motor does not rotate, tachometer feedback is absent, or run capacitor is open..

The primary root cause for Rosieres code E7 is: On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Calcium scale or fruit seed jamming pump volute, open main winding (~45–95 Ω), or defective BLDC inverter driver..

To resolve error code E7: Inspect circulation pump volute for debris. Spin rotor with screwdriver to ensure free turning. Measure motor winding resistance (~45–95 Ω). Press and hold Start/Cancel button for 6 seconds until all cycle lights extinguish, then switch off mains toggle switch.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Rosieres code E7 persists, the physical component causing On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Calcium scale or fruit seed jamming pump volute, open main winding (~45–95 Ω), or defective BLDC inverter driver. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

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.
