Samsung F01

Samsung error code F01 indicates: Samsung EcoBubble / AddWash / Bespoke AI Digital Inverter Washer: Motor phase imbalance fault F01; 3-phase BLDC motor inverter detects missing phase or unequal current consumption across UVW..

The primary root cause for Samsung code F01 is: On Samsung washing machines featuring EcoBubble foam generator, Digital Inverter BLDC drive motor, and VRT Plus active vibration reduction: Open stator winding on motor phase U, V, or W, broken connector pin, or blown IGBT output driver channel..

To resolve error code F01: 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). Power on, press and hold Spin Speed and Temperature keys together for 7 seconds until display clears or sounds a melody, then restart cycle.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Samsung code F01 persists, the physical component causing On Samsung washing machines featuring EcoBubble foam generator, Digital Inverter BLDC drive motor, and VRT Plus active vibration reduction: Open stator winding on motor phase U, V, or W, broken connector pin, or blown IGBT output driver channel. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test 3-Phase Motor Windings / Tacho Generator / Carbon Brushes across Across phase pins U-V, V-W, U-W on motor harness; across tacho pins. Expected nominal reading is 3Ω–6Ω (BLDC phase U-V-W) / 60Ω–180Ω (Tacho coil) / 1.5Ω–3.5Ω (Universal stator). Tolerance: BLDC phase winding values must be strictly balanced within ±0.3Ω. Hand rotation generates 1V–4V AC on tacho..

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.
