What you may notice

Safe checks, in order
Start with the simplest non-invasive check. Stop as soon as the error clears; repeated resets can hide a condition without correcting it.
Record the display
Photograph the complete code before removing power.
Finish any update
If the device is updating, allow it to complete without interruption.
Restart once
Use the documented power-cycle interval and reconnect directly to the approved outlet.
Stop if it returns
Repeated resets will not repair a failed harness or control board.
Know where to stop
Do not open energized control compartments or unplug internal connectors. Protect electronics from water.
When to call a technician or support
A persistent communication code requires service with the exact model and complete code available.
When you call, have the exact product model, the complete code or light pattern, and when it appeared.
