Boiler over heats and turns off

[Daveafsmith]

Hi everyone.
I have the old style boiler, basically last year it started not working after being on for 10 mins.. Replaced the pump and 3 way port valve cleared the lines, bled everything, cleaned it all out Etc. Literally done most things.

Basically it will work bit o my if I manually position the 3 port valve with the actual valve control taken off. It doesn't seem to change between heating and hot water. Is this a programmer issue or a pcb issue sitting th boiler, it can't be much else, surely.

Thanks for any help in advance. I gave up last year and spent the whole winter with the Emerson on, paying for it now.

When you remove the valve head does the spindle underneath move freely??

Whos the pump manufacturer ?

Valves open and clear ?

Has the system been vented properly and as above, both pump valves open? 3 port wired in correctly? Could be a timer issue?
