3 yrs old and the boiler keeps shutting down.Have had 3 diagnosis so far but not conclusive.1/It's a Biasi-they are trouble! 2/Diverter valve 3/Not diverter valve it's your PCB.
B.G. will come for a one off figure.Biasi not a problem but would recommend a service contract.I've been down this road before with the last house and to be honest the contract wasn't worth the paper.We are a rural area and the best heating engineers seem to be either on new build or contractual so any help would be great.The boiler fires up no problem on either DHW or CH.On CH ,the flame visibly reduces and then shuts off however if you turn the CH system off via the control and then back up to the temperature it fires up again for a short period.Eventually you have to totally let the system cool before attempting a restart.There is limited vision but there does not seem to be any attempt to re-ignite when it has shut down(no visible spark).Occasionally it will run nearly all night without a hiccup then the following day on and off .Guy at work says" it's blocked mate mine did that and I flushed it) works perfect nah!".
