OK - here's what is happening.
There is no hot water or central heating; when I re-start the boiler the green light shows, the fan goes on and then the amber light shows persistently - basically the boiler doesn't ignite.
I had an engineer down and he diagnosed a faulty gas-valve (which I then replaced); unfortunately this didn't sort things out ergo he stripped the entire system, cleaned the fan, unit-tested it and put it all back together. It still didn't work which mystified him...
I contacted Ariston who diagnosed a faulty Air-pressure switch but my engineer said that he checked it and it was fine. The Ariston guy had also suggested that moisture may have seeped into a plug-socket (?) or that a tube may be split or damaged. My engineer said that he hadn't checked this...
Any thoughts on what might be going wrong please?
