Possible Causes

Safety first: Unplug the freezer before opening the control panel.

Dry the panel: If condensation or spills reached the panel, allow it to dry completely. Do not use a hair dryer on high heat.
Clean around buttons: Wipe the panel surface with a slightly damp cloth and then dry. Ensure no debris is wedged around mechanical buttons.
Inspect UI board: Remove the panel and look for corrosion or burnt components.
Replace UI board: If buttons remain unresponsive or F12 persists, replace the user interface board with the correct Hotpoint-Ariston part.
