Potterton Performa Combi boiler problem

mag85ic

Hi All

I have a Potterton Performa combi boiler.It was working fine until last week but now it is missing some times.I mean when you open tap for DHW ,no hot water at all.The burner does not come on.

If I close and reopen the tab 2/3 times than it start working fine like no problem what so ever.Hot water CH all working good if its start running.

Some times all day no problems and some times have to close/re open the tap again and again to get the hot water.

I am worried as the winter is approaching.

Could any body please share the views as to what the problem can be.

Please help me to find out the exact problem.

Thanks

Thanks for reply ..

Is this is some thing I can change myself or do I need to call for boiler engineer.

Just want to mention that when not hot water than no central heating working. And when hot wot working than central heating working too.

Thanks

If the CH is playing up then it's not that. Are yiu having to reset the boiler? I'd call someone out

Hard to tell could be something like air pressure switch sticking, prone to problems on those, you need to call someone out
