I have the same gasoline model, also with the Multicontrol HD on my 2016 Transit 250. Mine has less than 40 hours on it, and I've gotten the F02 code twice. Both times I've powered the unit down (waited for all fans to shutoff) and simply restarted heat mode to get it to work.
In my case I believe it was fuel levels and/or the angle of the parking relative to the pickup location of the fuel line. My tank needs to be reading above 50% for the pickup to get adequate fuel into the line. The Ford pickup line is near the rear of the tank, so parking with the cab pointed downslope would make the fuel even less likely to get sucked up.
