Smart Battery Protect Error 1

I have a Snart Battery Pretect 220 installed between my loads abd the rest of the victron DC equipment. It had been working fine for 9 months, yesterday all dc went down on my boat. Traced it to the SBP. It showed a E1 short curcuit. Tested the rest of my loads and found no short curcuit, by passed the SBP with no issues. Removed all wires from the SBP and let it sit for a minute or two then tried to reconnect it in the system. Same error E1. Is my SBP fried?

What loads are connected?

Try to disconnect the output and restart the BP.

The load is the rest of the boat loads, about 600 watts. I removed the SBP completely (no wires) for about 2 minutes then reinstalled itm turned it on and it errored E1 in a few seconds. Every thing had been working fone for 9 months and I didn't change anything before the errors started happening.

Remove the output wire, restart the BP and let the output wire removed to let the BP start without anything connected to the output.
