Possible Causes
How to Fix / Troubleshooting
Safety warning: This error involves the high-voltage heating circuit. Do not attempt to probe live high-voltage wiring.
User checks:
- Test heating with a cup of water for 1–2 minutes. If water is only lukewarm or cold and E09 appears, internal components are likely failing.
- Listen for unusual noises (loud buzzing, arcing). If heard, stop immediately and unplug.
Professional actions (for reference):
- Measure magnetron current draw and compare to specification.
- Inspect and test the current sense circuit on the control PCB.
- Replace the magnetron or transformer if out of tolerance.
Recommendation: Due to the complexity and danger of high-voltage measurements, arrange service with a Candy-authorized technician.
