Actually Shapka is a word for Russian Berrete, an army cap, but later people started using it as a common term for a hat, which origially should be "kapa" :)

@David,

Pleasure! I thought at the time - this isn't documented anywhere, and it's so bizarre it needed to be :)

39p spent at Maplins and my Potterton Prima F 60 is purring like a kitten.

Thank you so much.

All the best Simon

@Kim, thanks for the tip, certainly agree on the design!

Hi, Ref Prima 60F
just another note that might help somebody else.
Reading through the comments, somebody asked the question (could the caps be at fault on a 15 month old pcb) Well the answer is yes and the last thing I expected. Mine was about 16 months old and looked like new inside. No sign of the usual bad joints at the base of the plug socket etc. I replaced all 3 caps, but the faulty one was the axial one (wires come out at either end) C7 22uF. Maplin p/n AT04E They don't do this in 100v or 103 degC versions so 63V had to do. Anyway when tested, the faulty one measured 4uF rather than 22uF

The problem with the boiler was: On fire up, it would run the fan for 5 sec then stop then run 5 sec again between 4 or 10 times before firing. It would never try to spark. Basically I guess it needs a few seconds more than 5 to allow enough diff pressure to pull the Air Press SW in

I carried out the flame safety test procedures shown in the manual after reinstalling the pcb and I would recommend this to others.

Given the application and location of the pcb, I have never seen such poor build quality. It is basically designed to fail after a couple of years max.

Regards Kim

Found your page via google when I returned home to find that there was no hot water and the Profile 80e wouldn't fire up.

Noticed some arcing and sparking from underneath the front right hand side of the PCB, whipped it out and found a nasty cracked dry joint.

Fired up the soldering iron and 5 minutes later the boiler was back working and the water was heating.

Thanks for your informative write up, if I do need to change the capactitors do need replacing in the future, I am well up to speed on getting the PCB out for another quick repair.
