Arthur Martin i70

Arthur Martin error code I70 indicates: Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher: Wash tub NTC temperature thermistor open or short circuit i70; temperature measurement circuit inoperative..

The primary root cause for Arthur Martin code I70 is: On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) models: NTC sensor internal pellet open or shorted (nominal 4.8–6.0 kΩ at 20°C; ~1.2 kΩ at 60°C), broken wiring harness in door hinge bend, or plug loose..

To resolve error code I70: Measure NTC resistance directly at sensor terminals (4.8–6.0 kΩ at 20°C). Check continuity of 2-wire harness through door hinge flex point. Hold Départ/Pause and Option buttons firmly for 5 seconds until the red indicator extinguishes and service memory resets.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Arthur Martin code I70 persists, the physical component causing On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) models: NTC sensor internal pellet open or shorted (nominal 4.8–6.0 kΩ at 20°C; ~1.2 kΩ at 60°C), broken wiring harness in door hinge bend, or plug loose. must be inspected or replaced.

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..

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.
