Whirlpool F01

Whirlpool error code F01 indicates: Whirlpool 6th Sense Supreme Care Heat Pump Tumble Dryer: Drum drive motor relay or triac failure F01; power PCB detects uncommanded drum rotation or shorted motor driver..

The primary root cause for Whirlpool code F01 is: On Whirlpool tumble dryers (Whirlpool 6th Sense sensor algorithms and WAVE / L1373 electronic platform architecture): Welded motor start relay contacts on control board, or short-circuited motor triac semiconductor..

To resolve error code F01: Disconnect mains power. Measure resistance across motor driver triac terminals (short = 0 Ω). Inspect power board for scorched relay pads. Rotate cycle dial to 6 o'clock, press Start 3 times, rotate to 7 o'clock, press Start 3 times, then return to Off.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Whirlpool code F01 persists, the physical component causing On Whirlpool tumble dryers (Whirlpool 6th Sense sensor algorithms and WAVE / L1373 electronic platform architecture): Welded motor start relay contacts on control board, or short-circuited motor triac semiconductor. 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.
