Possible Causes

Failed power relay on control board, Burned relay contacts, Control PCB trace damage, Loose wiring to high-voltage section

How to Fix / Troubleshooting

Safety: Unplug the microwave before any inspection. Do not remove the cabinet.

  • Confirm symptom: Place a cup of water inside and run for 1–2 minutes. If the turntable rotates and the light is on but the water stays cold and E06 appears, the power output control is likely faulty.
  • Reset electronics: Disconnect power for 5–10 minutes, then reconnect. Reprogram the clock and test again.
  • Check for burning smell: If you notice a burnt electronics smell from the control panel area, stop using the microwave and leave it unplugged.

Next step: The control board and its relays are internal components. Replacement requires disassembly and high-voltage safety procedures; schedule service with Bosch.
