Arthur Martin i43

Arthur Martin error code I43 indicates: Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher: Dynamic water level fluctuations alarm i43; abnormal pressure oscillations detected during circulation..

The primary root cause for Arthur Martin code I43 is: On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) models: Spray arms jammed against tall plates or cutlery, lower spray arm clogged with lemon seeds, or foaming from rinse aid overfill..

To resolve error code I43: Ensure upper and lower spray arms rotate freely by hand. Clean clogged spray arm nozzle orifices with a needle. Check for excessive foam. Hold Départ/Pause and Option buttons firmly for 5 seconds until the red indicator extinguishes and service memory resets.

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.
