Coffee maker does not power on at all; no lights or display when plugged in.

Safety first: Ensure the outlet is properly grounded. Unplug the coffee maker before opening any covers.

• Check outlet: Plug a lamp or phone charger into the same outlet to confirm it has power. Reset any tripped GFCI or breaker.
• Inspect power cord: Look for cuts, kinks, or burn marks. If damaged, the cord must be replaced; do not tape or splice it.
• Test power switch: On models with a mechanical rocker switch, ensure it clicks firmly. A loose or wobbly switch may be broken internally.
• Internal fuse (advanced): Remove the base and look for a small glass or ceramic fuse on the control board or power input. If blown, replace only with the same rating. If it blows again immediately, there is a deeper fault that needs professional service.

If the unit remains completely dead after verifying power and replacing a blown fuse once, the main control board or power switch circuit is likely defective.
