What to do
Why this happens
The issue may stem from a short in the display PCB key circuit, a malfunctioning display PCB, a stuck or shorted control panel button, or moisture/debris causing a short on the control panel.
How to fix it
If a button is stuck, try gently pressing around its edges. If the error keeps appearing, the control panel may need replacing — a technician can handle that.
