On Hotpoint cooktops: Missing neutral copper link bridge on terminal board, or neutral connected to second 400V live line in domestic wall junction.

Shut off power immediately. Inspect terminal box wiring diagram. Install copper bridge between N1 and N2 terminals. Verify true Neutral (0V to Earth). Disconnect mains power for 90 seconds, ensure no cookware rests on sensors, then re-apply power.

F47

Hob / Cooktop

Heating Element, Thermostat & Safety Fuse

Hotpoint Active Induction & CleanProtect Cooktop: LIN bus communication lost between touch UI and power filter PCB F47; master controller drops link to auxiliary filter board.

On Hotpoint cooktops: Loose multi-pin LIN bus connector, moisture condensation on filter board transceiver, or blown power supply resistor.

Inspect LIN bus harness connecting touch UI and filter PCB. Reseat connectors firmly. Verify 12V DC input to filter transceiver IC. Replace harness if damaged. Disconnect mains power for 90 seconds, ensure no cookware rests on sensors, then re-apply power.
