I changed over the syncro motor on the mid position valve to one I knew worked and it made no difference. I suspect it may be the printed circuit board on the mpv.
If i'm wrong can someone tell me what it could be or where I should be looking, if I may be correct can you confirm that so I can get a new mpv.
The boiler is a gloworm Ultimate.
Thanks.
