Display is on but buttons or rotary knobs do not respond to input.

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

Faulty keypad or encoder, Loose ribbon cable between UI and main board, Moisture ingress into control panel, Locked child-safety mode

Safety: Disconnect power before removing the front panel.

Check for lock mode: Consult the manual to see if a child lock or key lock is active and how to disable it.
Inspect ribbon cable: Remove the front cover and ensure the flat cable from the display/control panel to the PCB is fully seated.
Dry moisture: If there are signs of condensation, gently dry the area and correct any leaks.
Replace UI module: If still unresponsive, the control panel assembly may need replacement.
