Favorit i20

Favorit error code I20 indicates: Favorit SwissLine / DIVA SilentTech Fully Integrated Precision Dishwasher: Diagnostic fault code i20 registered by the microcomputer controller. Dishwasher drain timeout; wash water not evacuated from tub within 120 seconds (code i20).

The primary root cause for Favorit code I20 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: drain filter clogged with food scraps, sink siphon spigot obstructed, or drain pump impeller jammed. Metrological tolerance verification: drain pump motor stator winding resistance 140 Ω to 180 Ω at 20°C; 230V AC supplied during drain phase..

To resolve error code I20: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: clean sump microfilter, check drain hose for twists, inspect pump impeller for debris, and test stator coil (~160 Ω). 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 I20 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: drain filter clogged with food scraps, sink siphon spigot obstructed, or drain pump impeller jammed. Metrological tolerance verification: drain pump motor stator winding resistance 140 Ω to 180 Ω at 20°C; 230V AC supplied during drain phase. 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.
