Possible Causes

Worn or damaged keypad membrane, Moisture intrusion under control panel, Loose ribbon cable to control board, Control board input failure

How to Fix / Troubleshooting

Safety first: Unplug the coffee maker before working near the control panel.

Drying and cleaning:

  • If the panel was exposed to steam or spills, unplug the unit and let it dry in a warm, dry place for 24 hours.
  • Wipe the panel surface with a slightly damp cloth and then dry thoroughly.

Internal inspection (advanced):

  • Remove the front or top cover to access the keypad membrane and ribbon cable.
  • Ensure the ribbon cable is fully seated in the control board connector.

If specific buttons never respond while others do, the keypad membrane is likely worn and should be replaced. If all buttons are affected, the control board may be at fault.
