Hello Tony, sorry as I seem to have offended you. I changed the wax capsule
because I referred to the solution for someone else, I think the case was in 2005. The flow switch because it also may have been the problem. It was cheaper for me to change anything that may be wrong as it costs me...
sorry for the long delay. As the boiler is in my sons house in Bournemouth and I live in London, I took a diverter valve wax capsule and a flowswitch with me. I have changed both and the problem is still there, Boiler lights but won't stay on. Any ideas? I am going to B'mouth again weekend after...
you are probably right, I have no idea, as this is the first Puma I have seen.
If the diaphragm has gone faulty can I change just the diaphragm and where can I get it. Won't have a chance to do anything till next weekend as the boiler is in my sons house.
At the top right of the casing it says Puma 80, 80e and flowsure +. However it does have a swing down PCB and the differential or is it the flow switch (?) sits on the left of the diverter valve assembly.
Hi, I hope someone can help!! When HW tap is on the boiler turns on and the red light on the PCB lights, but it turns off after about 30 seconds and the light goes off, if the tap is left running is relights after about a minute and then turns off after 30 seconds.
