Iberna E18

Iberna error code E18 indicates: Iberna IDI / Standard Wash System Dishwasher: Low water level during circulation E18; circulation wash pump sucks air pockets causing cavitation and pressure loss..

The primary root cause for Iberna code E18 is: On Iberna dishwashers powered by Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Upside-down pots trapping excessive wash water, partial siphoning through low drain hose, or foaming detergent..

To resolve error code E18: Arrange hollow dishes so they drain freely. Ensure drain hose loop is at least 65 cm above floor. Pour 2 liters of water in tub and reset. 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 E18 persists, the physical component causing On Iberna dishwashers powered by Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Upside-down pots trapping excessive wash water, partial siphoning through low drain hose, or foaming detergent. 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.
