Hotpoint F25

Hotpoint error code F25 indicates: Hotpoint Active Induction & CleanProtect Cooktop: Rear induction zone center temperature sensor disconnect F25; glass ceramic sensor spring probe circuit open..

The primary root cause for Hotpoint code F25 is: On Hotpoint cooktops: Broken copper wire at coil center spring eyelet, oxidized plug on generator board, or cracked ceramic thermistor chip..

To resolve error code F25: Unclip glass top and access rear induction coil. Measure center spring NTC probe resistance (nominal ~100 kΩ at 25°C). Replace central coil sensor. Disconnect mains power for 90 seconds, ensure no cookware rests on sensors, then re-apply power.

Resetting power (unplugging for 5–10 minutes) clears temporary memory errors. However, if Hotpoint code F25 persists, the physical component causing On Hotpoint cooktops: Broken copper wire at coil center spring eyelet, oxidized plug on generator board, or cracked ceramic thermistor chip. must be inspected or replaced.

Set a digital multimeter to ohms (Ω). Disconnect power and test NTC Temperature Sensor Probe (Thermistor) across Across sensor pins 1-2 (unplugged harness). Expected nominal reading is 4.8kΩ–12kΩ (at 20°C–25°C). Tolerance: Negative temperature coefficient: resistance drops smoothly when warmed with fingers. OL = open circuit..

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.
