I have a potterton puma 80e. Ive had a few problems with the water pressure but thats ok now. However the reset light keeps going on when I try to put the central heating on. All is ok when I use the hot water.
When I reset, its ok for a couple of minutes but then goes on again, shutting it all down. Any ideas what the problem could be?

Depending on how long it takes to reset, It could be full of air or maybe your pump has packed up? both would sugest overheating.
