Chefman Keypad / Touch Control Failure

Buttons on the control panel are unresponsive or only work intermittently.

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

Moisture or coffee under keypad, Worn membrane switches, Loose ribbon cable to control board, Control board input failure

Safety first: Unplug the unit before cleaning the control panel.

Steps:

Wipe the control panel with a slightly damp cloth, then dry thoroughly. Do not spray cleaner directly onto the panel.
Allow the unit to sit unplugged for several hours to dry if moisture intrusion is suspected.
If only certain buttons fail consistently, the keypad membrane is likely worn and may need replacement.

Replacing the keypad or control board requires opening the housing and is best done by a technician.
