Hi, I have a boiler that has been here since I moved in around 5 years ago, I believe it's around 6 years old.
Now the problem I have is when I turn the CH on or open the hot water tap, the boiler makes it's usual start up noises and sounds like it is going to work fine then it clicks off with error code 7(safety thermostat error). The Main exchange is hot at the top, not so much at the bottom and after dumping all of the water out of it last night and topping back up it fired up and ran fine until I turned it off for the night.
I thought it might be the pump but it turns freely and is only luke warm and worked after dumping the contents of the system all over the kitchen![Wink ;) ;)](data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7)
Testing the valve for the expansion, air shot out with no water.
Any ideas?
Thanks, Phil
