Possible Causes

Faulty internal low-voltage power supply on control PCB, Loose mains connector, Damaged line filter board, Power surge damage to control PCB

How to Fix / Troubleshooting

SAFETY: Unplug the microwave before inspection. Do not touch high-voltage components.

E06 usually indicates the control board is not receiving stable low-voltage power.

  • Step 1 – External power check:
    • Plug the microwave directly into a known-good wall outlet (no extension cords or multi-plugs).
    • Avoid sharing the circuit with heavy appliances (kettle, heater).
  • Step 2 – Visual inspection (unplugged):
    • Remove the outer cabinet.
    • Inspect the mains input area and line filter board for burnt components or loose connectors.
    • Check the control PCB for obvious burn marks or bulging capacitors.
  • Step 3 – Connector reseat:
    • Firmly reseat the mains connector and low-voltage harnesses going to the control PCB.

If E06 persists, the control PCB or line filter board is likely damaged and should be replaced by a professional technician.
