DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Novomatic AL16
FAQ TREEWhat does error code AL16 mean on a Novomatic appliance?
Novomatic error code AL16 indicates: Novomatic GS / GSU Integrated & Freestanding Electronic Dishwasher Series: Diagnostic fault code AL16 registered by the microcomputer controller. Active condensation turbo drying blower fan motor open circuit or seized.
What is the root cause of Novomatic error code AL16?
The primary root cause for Novomatic code AL16 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: shaded-pole fan motor winding open circuit, condensation moisture seizing bronze bushing. Metrological tolerance verification: fan motor coil resistance 140-195 Ω at 20°C; power consumption 18W under 230 VAC 50 Hz..
How do I fix or resolve Novomatic error code AL16?
To resolve error code AL16: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: unplug drying fan connector and measure motor winding expecting 140-195 Ω, spin impeller blades to verify free rotation. 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.
Is it safe to clear Novomatic error code AL16 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Novomatic code AL16 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: shaded-pole fan motor winding open circuit, condensation moisture seizing bronze bushing. Metrological tolerance verification: fan motor coil resistance 140-195 Ω at 20°C; power consumption 18W under 230 VAC 50 Hz. must be inspected or replaced.
How do I test electrical resistance for Novomatic code AL16 using a multimeter?
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%..
What safety protocol must be followed before servicing Novomatic code AL16?
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.
