V-ZUG AdoraWash / Unimatic V2000-V6000 Swiss Precision Washer: Motor phase imbalance fault F01; 3-phase BLDC motor inverter detects missing phase or unequal current consumption across UVW.
On V-ZUG washing machines featuring AdoraWash vibration absorbing system (VAS), OptiTime energy logic, and brushless synchronous inverter drive: Open stator winding on motor phase U, V, or W, broken connector pin, or blown IGBT output driver channel.
Disconnect motor plug. Measure winding resistance across pairs U-V, V-W, and U-W with multimeter (all must read identical value ±0.2 Ω, ~5.5–11.5 Ω). Turn appliance off with the Main button. Press and hold Start/Pause and Spin Speed simultaneously for 5 seconds until 'Fn' code clears.
