Panasonic Keypad / Touch Input Failure

Buttons on the control panel are unresponsive or respond 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 under touch panel, Worn membrane switches, Loose ribbon cable to PCB, Cracked control panel overlay

Safety first: Unplug the unit.

Dry thoroughly: If the panel was recently cleaned with liquid, allow 24 hours of drying time.
Clean surface: Wipe with a dry, lint-free cloth to remove grease that may interfere with capacitive touch.
Test pattern: Plug in and test each button systematically. Note which ones fail.
Service: If specific keys consistently fail, the touch panel or its cable likely needs replacement.

Warning: Do not pry off the control panel overlay; this can permanently damage the keypad.
