Frequently Asked Questions: Airlux AL02
FAQ TREEWhat does error code AL02 mean on a Airlux appliance?
Airlux error code AL02 indicates: Airlux Optima / Silence 44dB Integrated Dishwasher: Diagnostic fault code AL02 registered by the microcomputer controller. Water drainage failure in dishwasher sump / filter obstructed..
What is the root cause of Airlux error code AL02?
The primary root cause for Airlux code AL02 is: On Airlux appliances engineered with Optima dual-arm spray hydraulics, electronic anti-leak float detection, and low-consumption BLDC wash motor: debris in sump drain impeller or drain hose restricted. Metrological tolerance verification: Drain pump coil 160 to 220 Ohms...
How do I fix or resolve Airlux error code AL02?
To resolve error code AL02: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: clean sump drain filter and check pump impeller. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Press and hold the Start/Reset button for 4 seconds until the program indicator light flashes and the drain pump runs for 30 seconds to empty the sump. Switch power off and on again.
Is it safe to clear Airlux error code AL02 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Airlux code AL02 persists, the physical component causing On Airlux appliances engineered with Optima dual-arm spray hydraulics, electronic anti-leak float detection, and low-consumption BLDC wash motor: debris in sump drain impeller or drain hose restricted. Metrological tolerance verification: Drain pump coil 160 to 220 Ohms.. must be inspected or replaced.
How do I test electrical resistance for Airlux code AL02 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 Airlux code AL02?
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.
