Puma 80 not firing up

rush8080 · 14 Nov 2013

Hi I Have a potterton puma 80. The pilot light is on but no hot water or CH (not firing up). checked the pump it's working fine. PCB is fine too and the fan seems to be working. What else should I look for? I'm moving house in 2 weeks time so I don't want any expensive repairs. Is there any way I could at least get hot water. Thanks in advance.

Ok called British gas and they sending an engineer. First half hour is £89. 1/2 hour to 2 hour £289 including parts and labour. Hope he can sort it out within half an hour.

How do you know the PCB "is fine" ?

So here I am with my crystal ball

and I see an air pressure switch that hasn't activated

and a fan that seems to be working but might not be

or maybe working but not fast enough.

Damn it's all gone cloudy now.

I think the spirits have left the building

It was the fan. It was working but not fast enough. The engineer said he will have to replace it and the cost is £289. I Told him I can't afford it, asked him to do a temporary fix. After a bit of WD-40 and oil The fan is working now. He can't give me any guarantee for the fan. He recommends that I replaced it. Hope it's going to last next 2 to 3 weeks.

So the total cost is £89. Thank you all for your quick response

Hi Agile.
I took the board and check for any burn marks. All the relays seems to be working fine and I changed the PCB a while ago.

I have to replace a lot of PCBs which have no visible indication of any fault but just are not working.

We don't recommend DIYers to open the combustion chamber where the fan is located.

We see that you are leaving a potential problem for the purchasers!

The work conscience comes to mind!

True but usually it's a dry joint at the top left of the board where the power goes in.
