DISPATCHAlways disconnect appliance from 230V/400V mains before opening panels. Use CAT III multimeter for circuit testing.
Frequently Asked Questions: Airlux I70
FAQ TREEWhat does error code I70 mean on a Airlux appliance?
Airlux error code I70 indicates: Airlux Optima / Silence 44dB Integrated Dishwasher: Diagnostic fault code i70 registered by the microcomputer controller. Sump water temperature sensor NTC open or short circuit..
What is the root cause of Airlux error code I70?
The primary root cause for Airlux code I70 is: On Airlux appliances engineered with Optima dual-arm spray hydraulics, electronic anti-leak float detection, and low-consumption BLDC wash motor: temperature sensor NTC open or short-circuit. Metrological tolerance verification: NTC 10 kOhms at 25C (1.2 kOhms at 80C)...
How do I fix or resolve Airlux error code I70?
To resolve error code I70: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: measure NTC probe resistance; replace if out of spec. 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 I70 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Airlux code I70 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: temperature sensor NTC open or short-circuit. Metrological tolerance verification: NTC 10 kOhms at 25C (1.2 kOhms at 80C).. must be inspected or replaced.
How do I test electrical resistance for Airlux code I70 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..
What safety protocol must be followed before servicing Airlux code I70?
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.
