Field Actions
DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Airlux PC
FAQ TREEWhat does error code PC mean on a Airlux appliance?
Airlux error code PC indicates: Current detect circuit malfunction or Current sensor malfunction.
What is the root cause of Airlux error code PC?
The primary root cause for Airlux code PC is: Defective PCB Power Supply Rails & DC Bus Filter Capacitors, open/short circuit in the wiring harness, or faulty connector on the electronic control board (pcb) & bus communications..
How do I fix or resolve Airlux error code PC?
To resolve error code PC: 1. Disconnect 230V mains power for 3 minutes. 2. Inspect wire harness and edge connectors on control board for loose pins or oxidation. 3. Inspect mechanical linkages and sensors associated with subsystem. 4. Reset: Power cycle reset: Disconnect appliance from 230V mains for 3 minutes. Press and hold Start/Power for 10 seconds while unplugged, then reconnect power.
Is it safe to clear Airlux error code PC by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Airlux code PC persists, the physical component causing Defective PCB Power Supply Rails & DC Bus Filter Capacitors, open/short circuit in the wiring harness, or faulty connector on the electronic control board (pcb) & bus communications. must be inspected or replaced.
How do I test electrical resistance for Airlux code PC using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test PCB Power Supply Rails & DC Bus Filter Capacitors across Across SMPS output electrolytic capacitors on low-voltage side (test bench verification). Expected nominal reading is Low-voltage rails: +5.0V DC (Logic), +12.0V DC (Relays), +3.3V DC (MCU). Relay coils: 200Ω–450Ω.. Tolerance: DC rail ripple must remain <50mV. Direct continuity (0Ω) across DC bus rails indicates dead short..
What safety protocol must be followed before servicing Airlux code PC?
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.
