Caple Electromagnetic Interference (EMI) from Hob

Hob causes interference with radio or Wi‑Fi when in use.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Faulty EMI filter, Missing earth connection, Damaged shielding, Incorrect installation of mains cable

Safety first: Ensure the hob is properly earthed; poor earthing can be dangerous and increase interference.

Technician steps:

Verify the integrity of the earth connection at the mains terminal block.
Inspect the EMI filter / mains input module for damage.
Ensure the mains cable is routed away from sensitive audio or RF equipment where possible.
Replace the EMI filter if internal capacitors or chokes are faulty.
