What Does Error E09 Mean?

The E09 error code on your Breville microwave indicates a low-voltage or power supply issue. This may manifest as the microwave not starting, the interior light failing to illuminate, and unusual buzzing sounds. If you encounter this error, it's essential to check the external power supply and inspect the power cord for any visible damage. A simple reset by unplugging the unit can sometimes resolve the issue. If the problem persists, internal inspection and servicing of power supply components may be necessary.

Common Symptoms:

  • Microwave displays E09 on the control panel
  • Interior light may not turn on
  • Unit will not start or run cooking functions

Possible Causes

  • Low internal voltage or power supply failure (medium)
  • Loose power cord or outlet connection (medium)
