Ariston SX20 mffice hot water ok but no CH?

My eurocombi operates in hot water mode ok.
When you switch on the heating the fan runs but the boiler does not start up.
Engineer called and couldn't be sure but reckons a new diverter valve at approx £250.(new diaprham fitted this year)
I'm not sure if I trust him. Does anyone have any other ideas.
Ps the circuit flow switch can be seen and seems to operate ok

if its the diverter valve u can pick up on easily. if its operating the circuit flow micro switch thens its doing its job. if after the flow switch is activated the fan runs then the flow switch is ok. it may be the pcb. without being there to diagnose its be hard to fault find. but i be careful of your plumber. british gas do a repair scheme for non members a £150 one of fee boiler repair includes all parts and labour. and if they cant fix it they dont charge give them a go its better than paying £250
