Possible Causes

Supply voltage out of range, Unstable power source, Internal power supply fault on PCB, Loose mains connection block

How to Fix / Troubleshooting

Safety first: Ensure the appliance is unplugged before checking internal connections.

  • Check mains supply: Verify that the wall outlet provides the correct voltage and frequency specified on the Grundig rating plate. Avoid using long extension leads.
  • Inspect mains cable and terminal block: Remove the rear cover over the mains terminal block and ensure all screws are tight and there are no signs of overheating.
  • Power reset: Unplug for 10 minutes, then reconnect directly to a known-good outlet.
  • PCB power supply check: If E27 persists with a stable supply, the internal power supply on the main PCB may be faulty and require replacement by a technician.
