How to Fix / Troubleshooting

Safety first: Unplug the coffee maker before checking the cord or outlet.

Use dedicated outlet: Plug the coffee maker into a separate circuit not shared with high-power devices like microwaves or toasters.
Inspect cord and plug: Look for damage or signs of overheating. Replace the appliance if the cord is compromised.
Avoid extension cords: Plug directly into a wall outlet to reduce voltage drop.

If flickering persists on a good circuit, the internal power supply or heater may be faulty and should be checked by a technician.
