Worcester 9.24 rsf problem

[tonyacktar]

Worcester 9.24 rsf no central heating.

I know its an ancient boiler and yes it will be replaced soon (with a baxi duo tec)

But just for knowledge sake...The DHW works fine but central heating does not work at all. All obvious things have been checked like c/h thermistor, programmer, air flow switch, pump and fan and they are all fine.
I assume its the pcb...but after looking at the wiring diagram have a niggle about the flow switches on the diverter valve..could it be that the switch is not flicking back to CH.

Could this be a possibility and is there any way of checking.

Thanks in advance.
