Novomatic AL08

Novomatic error code AL08 indicates: Novomatic GS / GSU Integrated & Freestanding Electronic Dishwasher Series: Diagnostic fault code AL08 registered by the microcomputer controller. Water softener salt container regeneration solenoid valve electrical circuit open.

The primary root cause for Novomatic code AL08 is: On Novomatic Austrian and Central European retail OEM chassis appliances engineered with Austrian retail OEM wash system with 1800W flow tube element (27-31 Ω), wash motor (95-125 Ω), and pressure membrane switch: solenoid actuator coil open circuit, salt crystal jamming valve plunger, or driver triac failed. Metrological tolerance verification: solenoid coil resistance 3.2-4.2 kΩ at 20°C; operating voltage 230 VAC 50 Hz..

To resolve error code AL08: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: unplug regeneration valve terminals at side of salt container and measure resistance expecting 3.2-4.2 kΩ; flush plunger with hot water. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: press and hold the Program selector and Start buttons together for 5 seconds until the display beeps and drain pump evacuates remaining water.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Novomatic code AL08 persists, the physical component causing On Novomatic Austrian and Central European retail OEM chassis appliances engineered with Austrian retail OEM wash system with 1800W flow tube element (27-31 Ω), wash motor (95-125 Ω), and pressure membrane switch: solenoid actuator coil open circuit, salt crystal jamming valve plunger, or driver triac failed. Metrological tolerance verification: solenoid coil resistance 3.2-4.2 kΩ at 20°C; operating voltage 230 VAC 50 Hz. 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.
