Possible Causes

Faulty internal low‑voltage power supply on module, Loose mains connection at terminal block, Damaged power module components, Brownout or unstable mains supply

How to Fix / Troubleshooting

Safety first: This involves mains and internal power circuits. Only qualified personnel should open the terminal cover or module.

  • Check mains stability: If other appliances dim or reset, have an electrician check your supply.
  • Power reset: Turn off the hob at the breaker for 5 minutes, then restore power.
  • Terminal inspection (qualified only): Have an electrician verify that the Grundig hob’s terminal block screws are tight and that there is no heat damage or discoloration.

If E8 persists with a stable supply, the internal power supply section of the module is likely faulty and the power module should be replaced.
