When I researched your meter I came to the conclusion it's a smart meter that can work in PAYG and Credit mode. I think you may have lost supply due to there being no credit on the meter before it was switched to credit mode (perhaps due to the balance being transferred to your electric account) and now it needs to be reset. We need to find out how to reset it.
If you want to tag someone in particular you can either just click on 'Reply' at the bottom of the post you want to respond to or you can type their forum name with an @ in front. That will alert them to your post.
So, I will tag @DebF_EONNext and @theunknowntech to request they kindly look at your post with photo above and see if we can get you some advice here.
