The boiler fires up then shuts down in around 10 seconds in both CH and DHW mode, it fires over again and shuts down over and over. I have gone through the faulting manual which ends at the point of "turning the plug" on the detector probe. This has now been replaced and the same fault is occurring.Does anyone know what is faulty??

rectification ?
Central heating thermistor??
now you've edited your post i suggest you call in someone qualified as you shouldn't be in the combustion chamber & that is where the fault may emanate. even if it doesn't some things should be checked that you are unable to do.

I have checked the thermister readings for resistance and all looks in spec with the manual
