Arthur Martin i59

Arthur Martin error code I59 indicates: Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher: Circulation pump motor speed runaway or tachometer mismatch i59; rotor speed exceeds command target..

The primary root cause for Arthur Martin code I59 is: On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) models: Cavitation in pump chamber caused by zero water intake or excessive foam, loose tachometer magnet, or inverter PWM control breakdown..

To resolve error code I59: Check tub water level (must submerge sump filter base). Check for excessive foam from detergent. Verify tachometer magnet mounting. 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 I59 persists, the physical component causing On Arthur Martin (Arthur Martin ASF Series / Calypso / Electrolux Luxe Dishwasher) models: Cavitation in pump chamber caused by zero water intake or excessive foam, loose tachometer magnet, or inverter PWM control breakdown. 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.
