Hi This is my first ever post on here, don't ban me yet!! let me help a bit and give a sound advise!! lol
Ok, you may ask your sister for the Service/User manual for her boiler, which she probably doesn't know where it is!!
Have a look in the manual, which normaly gives a fault diagnostics towards tyhe back, using flow charts, tells you how to diagnose a problem, some boilers now adays give a fault code, others you will hyave to go through a systamatical procedure, like you as a boiler repair man would know, for example when a demand is made for say CH, the room state must be set on, this signals tyhe boiler to start, the boiler has its own sequence of events that it must go through, each being more or less same but varies between certain types, so I would say follow these diagnostic steps and this might help- you find the problem, having a good multimeter is quite essential these days to find if sensors, switches etc are working.
hi msg2. the fault code is coming up as 1&3' which says the pressure/flow switch is inoperable. but changed flow switch and still nothing happens. elso changed hw thermister. its driving me mad, it is the boiler from hell lol.
