well, job done, decided to jump it and it seems fine, we'll find out how fine in the morning! seems to be pumping and circulating fine. hopefully it's the end of the hassle for a month or two!
interestingly it needed the eka code, as i expected, but it allowed me to put it in with the drivers window not set and i didnt have to set any windows.
anyways, stand by for next fault!!! lol!!!
