Thanks guys, it is definitely the fan then, as when everything is fired up is uses about 140 watts, so that would be about 110 for the pump and 30 for the fan. One thing that worries me is that this issue is not necessarily reproducible on demand. It is happening 75% of the time, but not 100%...

Hi, I have a WB Greenstar 8000, 35kw. Under warranty, serviced yearly. Installed 2 years ago. I noticed via our smart electric meter than something somewhere was consuming about 30 watts constantly. After much searching I noticed than something in the boiler is running all the time. It...

So a quick recap: The boiler will start, radiators heat up, hot water will be delivered via a tap but after about 15 minutes it will cut out, not a normal cut out, the flame, fan and pump all stop at once as if the power had been cut. No hot water or CH is then available until at some later...

Thanks for the reply. I thought about the thermistors, but whenever that kind of issue has come up the pump would always keep running until the x minute time out even though the boiler would shutdown. With this problem however, when this cuts out everything stop immediately, including the...

Thanks am trying to do a bit of initial investigation first but that may well be the end result.

Hi, I have a Ravenheat LS100 Silverstar. When the CH is on, it has started cutting out. When I say cutting out I mean everything immediately stops. The pump stops the fan stops, as if the power has been cut, but there is still power to the unit. Tapping the side of the control board housing...

Thanks for the replies. Would a faulty thermistor indicating a 20 degree drop override the anti-cycle device? Thanks so much for your help. Jamie

bump, any suggestions anyone? Thanks, Jamie

Hi, Thanks for reading this. I have a Ravenheat Silver Star LS100 that is approx ten years old. DHW is working fine. CH also seems to be working well. There is no thermostat or thermostatic valves in the house, it is just a manual on/off boiler. The only problem is that the...

Firstly thanks for all the replies, they were really helpful and wife is so happy! The pump was fine as it turned out (but worth checking), the problem, for anyone reading this is that the blow test it a complete waste of time (apart from maybe to check total blockage which would surely...

Thanks for the reply. Yes I wasn't sure about the blow test but there appears to be no resistance there. All the isolation valves are fully open. There is a fernox filter fitted that handily has an isolation valve above and below it. This is on the CH flow. Now if I turn the isolation valve...

Thanks for the reply. I took off the diverter valve and could blow through it easily as well (in the direction the CH would flow). Oddly the thermisters were changed a while ago, when the problem first started, but has gradually got worse. I have also now checked all the pipes going to the...

Anyone any ideas. Just really want to know, if you can blow through it easily if that means it is ok? Thanks.

Hi I have a ravenheat boiler. LS100. About 7 or 8 years old. Anyway for a while it has had the overheat / lockout issue when the central heating is on. This seems to be the classic of put your hand on the flow pipe and after a few minutes it gets very very hot and the boiler shuts down...

Thanks for your help. I see a fan costs about £150 and the switch about £30. I could get both but would rather avoid that if there was someway of determining if it is the fan or the air pressure switch. As the air pressure switch only seems to take a very small blow to trigger I am thinking...
