Arthur Martin iF1

Arthur Martin error code IF1 indicates: Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher: Water level overfill warning detected by analog pressure sensor iF1; tub water level exceeds maximum safety mark..

The primary root cause for Arthur Martin code IF1 is: On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) models: AquaStop solenoid valve leaking water past its seat when unpowered, triac on main PCB shorted, or high detergent foam triggering false level..

To resolve error code IF1: Disconnect power: if water continues filling tub, replace defective AquaStop inlet valve. If water stops, inspect filling triac on PCB. 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 IF1 persists, the physical component causing On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) models: AquaStop solenoid valve leaking water past its seat when unpowered, triac on main PCB shorted, or high detergent foam triggering false level. must be inspected or replaced.

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%..

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.
