Faure i5D

Faure error code I5D indicates: Faure FDF Series / Clean&Dry / MaxiWash Dishwasher: Circulation pump inverter communication line timeout i5D; main motherboard loses UART link with inverter..

The primary root cause for Faure code I5D is: On Faure (Faure FDF Series / Clean&Dry / MaxiWash Dishwasher) models: Loose 4-wire serial communication cable between main board and motor inverter, cut wire, or missing logic power supply to inverter..

To resolve error code I5D: Check continuity of 4-wire serial interconnect harness. Verify 12V DC auxiliary logic power supply arriving at inverter board. Press and hold Départ/Pause and Annulation buttons for 6 seconds until all status indicators flash synchronously and clear fault memory.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Faure code I5D persists, the physical component causing On Faure (Faure FDF Series / Clean&Dry / MaxiWash Dishwasher) models: Loose 4-wire serial communication cable between main board and motor inverter, cut wire, or missing logic power supply to inverter. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

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.
