Iberna EF

Iberna error code EF indicates: Iberna IDI / Standard Wash System Dishwasher: Flowmeter pulse overflow anomaly EF; impulse count exceeds maximum safety tank volume during filling phase..

The primary root cause for Iberna code EF is: On Iberna dishwashers featuring Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: 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 button for 5 seconds until buzzer sounds, close door to allow pump-out cycle to complete, then switch off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Iberna code EF persists, the physical component causing On Iberna dishwashers featuring Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: 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.
