Potterton Prima 50F wont start

[guilbert53]

I have a Potterton Prima 50F that is trying to start heating the water, but every time the thing starts up it goes for about 5 seconds then stops again.

I then tries again, but after another 5 seconds it stops again. It keeps doing this over and over again so I have turned it off.

It is about 18 years old, and we did have the main "circuit board" replaced a year ago but it has run OK ever since.

Does it sound easy to fix?

Is it time to replace the boiler? (I wish I had taken advantage of the boiler scrappage scheme, but I believe it has finished)

the PCB has gone again I reckon

is it still under guarantee?

The boiler or PCB?

No idea about the PCB, it was fitted (by a central heating guy) about 15 months ago (about January 2009)

That on/off you describe is classic pcb failure.Easy to change.Scrappage scheme has stopped.18 yrs is a good life and most parts are still available for that boiler,but it's not that efficient.Good time for a change.

If we swapped the bolier for a like for like (same make or different) what cost are we talking about.

For the boiler

For fitting it

Rough guide is enough.

dont change the boiler get someone in to change the PCB

no boiler on the market is as realiable as the old prima/profile IMHO
