Frequently Asked Questions: Favorit I70
FAQ TREEWhat does error code I70 mean on a Favorit appliance?
Favorit error code I70 indicates: Favorit SwissLine / DIVA SilentTech Fully Integrated Precision Dishwasher: Diagnostic fault code i70 registered by the microcomputer controller. Dishwasher wash tub water temperature NTC thermistor sensor circuit open or shorted (code i70).
What is the root cause of Favorit error code I70?
The primary root cause for Favorit code I70 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: internal thermistor bead fractured, wiring harness damaged in door hinge bend, or connector dislodged. Metrological tolerance verification: NTC thermistor resistance 4.8 kΩ at 25°C, dropping to 1.2 kΩ at 60°C; values <200 Ω or >100 kΩ indicate fault..
How do I fix or resolve Favorit error code I70?
To resolve error code I70: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: unplug sensor connector at bottom sump housing, measure resistance at ambient 25°C, and test wire continuity. 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.
Is it safe to clear Favorit error code I70 by resetting power?
Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Favorit code I70 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: internal thermistor bead fractured, wiring harness damaged in door hinge bend, or connector dislodged. Metrological tolerance verification: NTC thermistor resistance 4.8 kΩ at 25°C, dropping to 1.2 kΩ at 60°C; values <200 Ω or >100 kΩ indicate fault. must be inspected or replaced.
How do I test electrical resistance for Favorit code I70 using a multimeter?
Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..
What safety protocol must be followed before servicing Favorit code I70?
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.
