I’ve got an Ariston Eurocombi which is running a small system with only 3 radiators, and 2 sinks.
For a while we’ve had a problem with the boiler tripping out and the overheat LED on. Water is still pumped around the system (cold) and the fan is on. The boiler switches on once you press the button again. But over time its been happening more and more frequently, and now it trips out every time you put the radiators on for more than about 30 mins. The hot water works fine as long as you switch the boiler to just hot water, and not run the radiators on timer.
Also, strangely, if you select both but don’t put the timer on. The boiler continues to fire after the hot water tap is closed, and the radiators warm up for a while until the boiler stops firing. Sometimes it doesn’t trip out when the radiators warm up this way, but occasionally it does.
I’m on that British Gas homecare scheme, and they seem to have tried all sorts. We’ve had the circuit board replaced, the air pressure switch, a new diaphragm, new temperature sensors, made sure there is a bypass radiator – all sorts. But the problem just continues to get worse.
In fact new problems are now starting – when I turn the taps on the boiler starts making a deafening foghorn noise that then vibrates through the pipes and house.
Basically I’m beginning to lose patience with the thing, and gear myself up for replacing the boiler. But it can’t be more than a few years old.
Anyone got any ideas?
