Rosieres EF

Rosieres error code EF indicates: Rosières RLI / RDS Grande Capacité Built-in Dishwasher: Flowmeter pulse overflow anomaly EF; impulse count exceeds maximum safety tank volume during filling phase..

The primary root cause for Rosieres code EF is: On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Siphoning water leaking continuously out of drain hose during fill, or defective pressure switch failing to register water depth..

To resolve error code EF: Check drain hose standpipe height (must be between 65 cm and 100 cm). Clear pressure switch dome in sump. Check pressure transducer contacts. 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 EF persists, the physical component causing On Rosières dishwashers featuring Grande Capacité built-in hydraulic circuit, triple-arm spray system, and acoustic soundproofing: Siphoning water leaking continuously out of drain hose during fill, or defective pressure switch failing to register water depth. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Mechanical Pressure Switch Contacts / Inductive Frequency Sensor across Across switch spade contacts with harness unplugged; electronic output: 40Hz–50Hz frequency signal. Expected nominal reading is Mechanical: Continuity 0.0Ω–0.2Ω (Empty: 11-12, Full: 11-14). Electronic: 20Ω–45Ω coil resistance.. Tolerance: Mechanical switch contacts must transition cleanly on gentle breath pressure. Coil ~22Ω ±5%..

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.
