Favorit iF1

Favorit error code IF1 indicates: Favorit SwissLine / DIVA SilentTech Fully Integrated Precision Dishwasher: Diagnostic fault code iF1 registered by the microcomputer controller. Dishwasher emergency overfill water safety switch tripped, drain cycle initiated (code iF1).

The primary root cause for Favorit code IF1 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: inlet water solenoid valve mechanically stuck open, triac shorted on power board, or heavy foam build-up. Metrological tolerance verification: overfill safety pressure switch contact opens when water depth >35mm above fine filter, triggering drain..

To resolve error code IF1: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: isolate water supply, inspect inlet valve seat for grit, verify triac switching voltage, and clear foam residue. 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 IF1 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: inlet water solenoid valve mechanically stuck open, triac shorted on power board, or heavy foam build-up. Metrological tolerance verification: overfill safety pressure switch contact opens when water depth >35mm above fine filter, triggering drain. 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.
