Buttons or touch keys work intermittently, require very hard presses

Safety Warning

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

Aging membrane switches, contaminated touch surface, drift in capacitive touch calibration, loose control panel mounting

How to Fix / Troubleshooting

Safety first: Turn off power before removing the control panel.

Clean surface: Thoroughly clean the glass or plastic over the touch area with a mild cleaner and dry completely.
Check panel mounting: Ensure the control panel is firmly mounted and not flexing when pressed.
Inspect keypad ribbon: For membrane keypads, reseat the ribbon cable and check for cracks or wear.
Replace keypad or touch board: If specific keys remain unreliable, replace the keypad membrane or touch PCB as a unit.
