Had similar problem. Dousing the fan motor with WD40 did the trick - careful it's flammable! But looks like the motor is on it's way - and £130 to replace.

The hot water works ok but the central heating not working the control sytems indicates that it should be running but fails to ignite the wall thermostat when tested is opening and closeing

Sounds like the selonoid for the flame rectification

hello mate,check to see if the fan is seized at the top where the flue is,BE SURE TO TURN OFF THE ELECTRICS FIRST!!
I had the same problem,and found that the bottom bearing of the motor was stiff/seizing.I managed to free it off,and go it to spin freely by hand,switched the elecs back on and it fired up!!
