Iberna AL05

Iberna error code AL05 indicates: Iberna IDI / Standard Wash System Dishwasher: Water filling timeout alarm AL05; wash tank does not fill to operating level within program timeout limit..

The primary root cause for Iberna code AL05 is: On Iberna dishwashers utilizing Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Scaled water supply tap, blocked metal strainer mesh in inlet hose connector, or defective inlet valve (~3.5–4.5 kΩ)..

To resolve error code AL05: Check faucet flow rate with bucket test. Remove supply hose and rinse out particulate debris from inlet filter. Measure valve solenoid (~3.5–4.5 kΩ). 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 AL05 persists, the physical component causing On Iberna dishwashers utilizing Standard Wash System hydraulic circuit, solenoid fill valve control, and heating element flow-through tube: Scaled water supply tap, blocked metal strainer mesh in inlet hose connector, or defective inlet valve (~3.5–4.5 kΩ). 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.
