Favorit i81

Q: What does error code I81 mean on a Favorit appliance?

Favorit error code I81 indicates: Favorit SwissLine / DIVA SilentTech Fully Integrated Precision Dishwasher: Diagnostic fault code i81 registered by the microcomputer controller. Dishwasher door user interface capacitive touch sensor keys unresponsive or ESD lockup (code i81).

Q: What is the root cause of Favorit error code I81?

The primary root cause for Favorit code I81 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: moisture condensation behind touch glass panel, missing chassis earth bonding, or capacitive controller latchup. Metrological tolerance verification: chassis earth bonding resistance from door frame to main earth pin <0.1 Ω; 5V DC supply ripple <30 mV..

Q: How do I fix or resolve Favorit error code I81?

To resolve error code I81: Disconnect mains power before servicing. Unplug the harness at the main PCB and use a calibrated digital multimeter: dry door control cavity thoroughly, verify chassis green-yellow earth bonding wire (<0.1 Ω), and power cycle. 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.

Q: Is it safe to clear Favorit error code I81 by resetting power?

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Favorit code I81 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: moisture condensation behind touch glass panel, missing chassis earth bonding, or capacitive controller latchup. Metrological tolerance verification: chassis earth bonding resistance from door frame to main earth pin <0.1 Ω; 5V DC supply ripple <30 mV. must be inspected or replaced.

Q: How do I test electrical resistance for Favorit code I81 using a multimeter?

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..

Q: What safety protocol must be followed before servicing Favorit code I81?

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.

1. Pre-Intervention Electrical Safety Protocols

!Electrical Safety Protocol: Isolate 230V mains power before accessing the lower pump housing.
!Prepare a shallow basin and absorption towels: expect 3 to 10 liters of stagnant trapped water upon filter opening.
!Beware of sharp foreign objects (broken glass, needles, screws) trapped inside the impeller cavity.

3. Preliminary Mechanical & Visual Checks

Unscrew coin trap filter and clear all foreign debris (coins, hairpins, bra underwires).
Rotate pump impeller manually: synchronous magnetic rotors should snap cleanly in 90° intervals without jamming.
Check drain hose for kinks, blockages, or unpunched sink spigots; verify drain height is between 65cm and 100cm.
