Possible Causes

Loose UI ribbon cable, failed user interface board, failed main control board, power surge damage

Safety first: Unplug the unit before removing the console.

Reseat UI ribbon: Remove the console and carefully unplug the flat ribbon cable between the UI and main control. Inspect for cracks or corrosion, then reinsert fully.
Check for moisture: If the console area is damp, dry thoroughly and correct any leaks or excessive steam exposure.
Board substitution: If reseating does not help, one of the boards is likely defective. Replace the user interface board first (most common), then the main control board if needed.
