Safety first: Disconnect power before removing the control panel.

Steps to diagnose and fix:

Inspect buttons: Press each button individually and feel for normal travel. If a button feels stuck, gently work it back and forth.
Clean around buttons: Use a soft cloth slightly dampened with mild soap solution to clean around the buttons. Do not allow liquid to enter the panel.
Access keypad: Remove the trim or screws securing the control panel to access the keypad and ribbon cable.
Check ribbon cable: Ensure the cable is fully seated and not damaged. Reseat both ends.
Replace keypad/UI board: If F2 persists, replace the BODEGA keypad or touch control board assembly.

When to call a professional: If you are not comfortable disassembling the control panel, contact a technician.

Display shows F2 and the unit may not respond to temperature adjustments.
