Hi,

I have an old Potterton Prima 40F in my house, which I'm guessing is 10-20 years old.

When I moved into the property in the winter of 2014, I had the same fault as I've seen tonight.

I can hear a click, the boiler fan starts up and then a click and the fan stops. This repeats again and again. I've read a lot of the times it's the PCB.
At the time I got a gas engineer out, told him what I had seen on forums etc but left him to investigate. He said it was the fan.
Replaced the fan and it did work a little better, but the fault has still been there, although it might have only taken 5 attempts to fire up in the past.

Now there is a fix to this, when it's mid fire up, if I hit the front panel near the flame window, it fires up pretty much all the time. (Video at the bottom)

Tonight I let it run for 15 minutes and it didn't fire up at all, I hit the panel on the next ignition and it worked.

I've just let it run naturally and after 25 minutes, it did fire up on it own.

I would say the fault has always been there since I moved in, but in the past only taken 10 fire ups maximum to kick in.

Any ideas? Could it be something in the ignition, electrode area?

Thanks for any assistance :)



 
You remind me of the Fonz ( happy days , sorry if you are too young to understand) belting the juke box to get free songs .

Come on pal , you shouldnt have to thump a boiler to get it to work , get a GS reg guy to take a look .
