Unit does not power on at all; no lights, no sounds.

Safety first: Ensure your hands are dry and the area is not wet before working with mains connections.

• Check outlet: Test the wall socket with another appliance to confirm it has power.
• Inspect plug and fuse: For UK Swan models, open the plug and check the fuse. Replace with the correct rating if blown.
• Examine power cord: Look for visible damage. If damaged, the cord must be replaced.
• Internal check (advanced): With the unit unplugged, remove the rear/bottom panel and inspect the power supply board for burnt components or loose connectors.

If there is still no sign of life after verifying the plug, cord, and outlet, the internal power supply or main control board likely needs replacement by a qualified technician.
