Safety first: Unplug the microwave before opening any covers. Mains voltage is dangerous.

1. Check the wall outlet: Plug another high-load appliance (like a kettle) into the same socket to confirm it supplies stable power. Avoid using long extension leads or multi-way adaptors for the microwave.
2. Inspect the mains plug and cable: Look for damage, overheating, or loose pins. If the plug or cable is damaged, have it replaced by a qualified electrician.
3. Power reset: Unplug the microwave for 10 minutes, then plug directly into a known-good wall outlet and test again.
4. Internal checks (advanced): With the unit unplugged, remove the outer cover and inspect the mains filter board, internal fuse, and wiring for signs of burning or loose connections. Replace a blown internal fuse only after identifying and correcting the underlying fault.
5. If E10 continues: The control PCB's low-voltage power supply may be defective and will require professional repair or replacement.
