Samsung E07

Samsung error code E07 indicates: Samsung EcoBubble / AddWash / Bespoke AI Digital Inverter Washer: Motor drive velocity anomaly E07; control module detects sudden motor acceleration or missing tachometer frequency feedback..

The primary root cause for Samsung code E07 is: On Samsung washing machines featuring EcoBubble foam generator, Digital Inverter BLDC drive motor, and VRT Plus active vibration reduction: Loose tachometer coil magnet on motor shaft, open tachometer winding (~65–140 Ω), or shorted motor Triac..

To resolve error code E07: Inspect tachometer magnet tightening on rotor shaft. Measure tachometer winding resistance (~65–140 Ω). Verify motor wiring harness continuity. 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 E07 persists, the physical component causing On Samsung washing machines featuring EcoBubble foam generator, Digital Inverter BLDC drive motor, and VRT Plus active vibration reduction: Loose tachometer coil magnet on motor shaft, open tachometer winding (~65–140 Ω), or shorted motor Triac. 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.
