Possible Causes

Loose power plug or outlet, Faulty power strip, Internal loose wiring, Failing control board

How to Fix / Troubleshooting

Safety first: Unplug the unit before moving or inspecting cords.

Check external power:

  • Plug the coffee maker directly into a wall outlet, not a power strip.
  • Test a different outlet if possible.

If flickering persists on a known-good outlet, internal wiring or the control board may be faulty and should be serviced by a professional.
