Westinghouse F

Westinghouse error code F indicates: Westinghouse WHI Series / Induction Cooktop: Pan detection symbol F flashing; cooking zone cannot detect magnetic cookware or pan diameter is too small..

The primary root cause for Westinghouse code F is: On Westinghouse (Westinghouse WHI Series / Induction Cooktop) models: Cookware made of non-ferrous material (copper, glass, pure aluminium), pan base deformed and lifted away from glass, or pan placed off-center..

To resolve error code F: Test base of cookware with permanent magnet (must attract firmly). Ensure cookware base covers at least 70% of zone cross-hairs markings. Press Start/Pause together with Temp button for 5 seconds to exit service diagnostic mode and clear persistent EEPROM alarm.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Westinghouse code F persists, the physical component causing On Westinghouse (Westinghouse WHI Series / Induction Cooktop) models: Cookware made of non-ferrous material (copper, glass, pure aluminium), pan base deformed and lifted away from glass, or pan placed off-center. 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.
