Favorit iF2

Favorit error code IF2 indicates: Favorit SwissLine / DIVA SilentTech Fully Integrated Precision Dishwasher: Diagnostic fault code iF2 registered by the microcomputer controller. Dishwasher analog pressure transmitter zero-point baseline voltage drift during drain (code iF2).

The primary root cause for Favorit code IF2 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: fatigued piezoresistive silicon diaphragm, water droplet standing in capillary tube, or DC supply drift. Metrological tolerance verification: zero-level reference voltage must be 0.50V ± 0.05V DC when completely drained; drift >0.15V triggers code iF2..

To resolve error code IF2: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: disconnect capillary hose, blow dry with warm air, inspect sump nipple for grease blockage, and check 5V DC line. 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 IF2 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: fatigued piezoresistive silicon diaphragm, water droplet standing in capillary tube, or DC supply drift. Metrological tolerance verification: zero-level reference voltage must be 0.50V ± 0.05V DC when completely drained; drift >0.15V triggers code iF2. 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.
