Favorit i71

Favorit error code I71 indicates: Favorit SwissLine / DIVA SilentTech Fully Integrated Precision Dishwasher: Diagnostic fault code i71 registered by the microcomputer controller. Dishwasher wash water over-temperature (>80°C recorded during low-temperature cycle) (code i71).

The primary root cause for Favorit code I71 is: On Favorit SwissLine and European precision appliances built for high durability engineered with Hydro-Flow wash circulation pump with tachometer (80-120 Ω), 2000W flow-through heater (25-28 Ω), electronic analog pressure transmitter, turbidity optic sensor, and AquaStop base pan float switch: heating relay contacts welded shut on power board or triac failure keeping element energized continuously. Metrological tolerance verification: heating relay contact resistance across normally open pins must be infinite (>10 MΩ) when coil de-energized..

To resolve error code I71: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: disconnect power immediately, test heating relay contacts on main control board, and replace board if welded. Inspect contacts for pin oxidation or loose terminals. Replace defective part if out of tolerance, re-energize and clear error: Press and hold Start/Reset button for 4 seconds until drain pump initiates, then turn off power for 60 seconds to clear active error code.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Favorit code I71 persists, the physical component causing On Favorit SwissLine and European precision appliances built for high durability engineered with Hydro-Flow wash circulation pump with tachometer (80-120 Ω), 2000W flow-through heater (25-28 Ω), electronic analog pressure transmitter, turbidity optic sensor, and AquaStop base pan float switch: heating relay contacts welded shut on power board or triac failure keeping element energized continuously. Metrological tolerance verification: heating relay contact resistance across normally open pins must be infinite (>10 MΩ) when coil de-energized. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test Drain Pump Motor Stator Coils across Across pump motor spade terminals (L-N unclipped). Expected nominal reading is 160Ω–220Ω (Sync 230V) / 20Ω–45Ω (3-Phase BLDC). Tolerance: ±10% balance. Insulation resistance between coil and motor chassis must exceed 20MΩ..

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.
