Display or indicator lights flicker or dim during brewing.

Safety first: If lights flicker along with a burning smell or popping sounds, unplug immediately.

• Use a dedicated outlet: Plug the coffee maker directly into a wall outlet without sharing with high-draw appliances like microwaves or toasters.
• Inspect cord and plug: Check for heat at the plug after brewing. A hot plug indicates poor contact and potential hazard.
• Test on another circuit: Move the coffee maker to a different outlet on another circuit to rule out house wiring issues.
• Internal inspection (advanced): With the base removed (unplugged), check for loose connectors on the control board and signs of heat damage.

Continued flickering suggests an internal power supply or heater issue that should be addressed by a technician.
