My boiler hasn’t been working for the last 2 months. First it seemed like the pump had gone, so I spent £90 on Labour and £120 on a new pump… since then the boiler still hasn’t worked. It’s had 3 new pumps (which I haven’t paid for), and a number of new sensors. It would run for a while and then stop, usually next morning, from that point on it would refuse to fire up.
Brian, the boiler man has tried his hardest but to no avail. Finally today SIME, the boiler manufacturer came up with the answer; the boiler was wired up wrong when it was installed 2 years ago! The problem appears to be that there should be a connection between the control unit and the boiler that affectively keeps the boiler constantly live, in standby state if you like. This wire, among others, is missing and thus when the boiler needs to power down it just cuts off rather than going into standby. The affect is that the boiler is being turned on/off many many times a day. This has burnt out the motherboard ( don’t let anyone tell you that standby buttons are bad because they use too much power ) and this now needs replacing along with the new wiring… so it looks like another £250 to get it fixed!
