Possible Causes

Unstable mains supply, Generator or inverter power with poor quality, Loose neutral connection, Internal mains filter fault

User checks:

Verify that the hob is connected to a stable mains supply, not to a portable generator or inverter unless specifically approved.
If lights in the home flicker or other appliances behave erratically, contact an electrician to check the supply.

Technical checks (electrician/technician):

Measure mains voltage and frequency at the hob connection under load.
Inspect and tighten all connections in the distribution board and hob terminal block.
If supply is stable but E3 persists, test or replace the mains filter / input board.
