Hamilton Beach Intermittent Power / Voltage Drop

Display and lights flicker or reset during brewing.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Loose power cord connection, Weak household circuit, Internal loose wiring, Failing control board power supply

Safety first: Unplug before inspecting the cord or base.

External checks:

Plug the coffee maker directly into a different wall outlet (no power strip).
Avoid sharing the circuit with high-draw appliances (microwave, toaster).

Internal wiring (advanced):

Remove the bottom cover and gently tug on wire connectors to ensure they are secure.

If flickering persists on a known-good circuit, the control board’s power supply is likely failing and the board should be replaced.
