F2E1 — UI Stuck Button

What does F2E1 mean?

This fault indicates that the user interface (UI) is detecting that a button is continuously activated, as if it's being held down. This can prevent normal operation, cycle selection, or diagnostic entry.

• A button on the user interface is physically stuck or jammed.
• Debris or foreign material lodged under a button.
• Faulty user interface board causing a button to register falsely.
