ah , ok been long weekend!
no multimeter here to test at mo, if pressure switch is at fault can this be easily replaced?
do the red and white tubes just come away or are they sealed?
no gas running through these I take it!!!! Poor design on this boiler as the pressure tubes get trapped if not very careful when putting the small access panel at the bottom back on!
Does pressure switch activate prior to fan in the installers manual details?

It was the fan siezed. Fixed rate repair so ended up expensive for engineer just to oil the fan!
Hoped it was PCB or Replacement fan to get my moneys worth!
Engineer said not normal oil they use, does anyone know what that stuff is called (he said non flammable!)
