oil central heating not working please help!!!

[highbury44]

My problem is that although my boiler works to heat the water it will not come on when i switch my heating on,even though the light on the programmer box comes on.Any ideas as to what the problem could be?Many thanks

Diverter valve or pump.

Thankyou for your reply.It seems to be the diverter value since if i move the lever the water is pumped through the radiators.Unfortunatley the lever will not stay in postion and keep the valve open.Does that mean it needs replacing?and if so is it a difficult DIY job.John

Hi i have changed the motor on the diverter and everything works fine except i can not get hotwater on its own ,when i switch on the hotwater,as the central heating comes on at the same time.I can however when i switch on the central heating just get the heating only.Any suggestions?
