Possible Causes

Failed low-voltage power supply on control board, Blown internal fuse, Shorted component on PCB

Safety first: Disconnect from mains. Do not attempt to bypass internal fuses.

Check external supply: Verify that the circuit breaker has not tripped and that the hob is receiving power.
Internal inspection (advanced): A technician can open the unit and check the internal fuse and power supply components for failure.

When to call a technician: Er05 almost always requires board-level repair or replacement.
