Potterton Combi 80 problem

Yasin · 24 Oct 2006

Hi Everyone

I have got a Potterton combi 80.
when i turn on the central heating the boiler fires up and stays on for around 20 second, it then shuts down for about a minute and then fires up again for 20 seconds and switches off again, this sequence keeps happening. My hot water is fine.

Any help would be greatly appreciated !!

Thanks

Most common cause is a sticking divertor valve. Do you get any heat in the flow pipe from the boiler?
