EB3A - DC SHORT - code 2-10

I purchased a Bluetti EB-3A in October 2022.
An issue I’ve had twice in the last two months is a DC “SHORT” code 2-10, even when nothing is plugged in. After a few days, it resets. I tried to reach Bluetti for guidance but could not get them to answer the phone. :-(!
I’ve tried to update the firm firmware, but it does not seem to want to update…
