I have a problem with the DHW (CH works fine). When the CH is on and boiler pressure goes upto 2bar if I try to run DHW it will fire the burners but stop after a few seconds. But, if I run DHW when CH not on and pressure of boiler down around 1.25/1.5bar DHW works fine. I changed the Flowswitch a few months ago and have recently checked the diaphragm so thats not the problem. Any suggestions?

Cheers
