Hi all,

as as title I have this issue with the boiler, the help manuals say DHW flow switch or a pump issue..... But,

when he the boiler is in fault and we go out or leave it, it seems to reset itself and we've come home to the radiators warms or hot waster available.

also if I open a tap or turn the shower on and turn the selector switch to DHW and/or DHW&CH from off it will produce hot water but once the shower is turned of it will fault within 5 minutes.

again I left it in fault last night, woke up this morning to it warming the house...for an hour or so. And it's been like this all day.

the other strange thing is neon b should flash every 5 sec to signify there is a 240v supply. It doesn't always do this, but there is defo 240v on my multimeter.

any pointers would be fantastic. Oh and neon B flashes every second
