Hi , does the boiler try to start ? Can you hear any sounds ?
Customer: replied 1 year ago.
The fan and possibly the pump are running

Can you tell me what your pressure gauge reading is? please
Customer: replied 1 year ago.
1.5 Bar

Thanks.it sounds like the boiler is reaching the fan and pump stage, then stopping. This may be to either the air pressure switch faulty and so not recognising the fan is running, or the temperature sensor faulty( common in these boilers ) and so the boiler not recognising the need for heat. Both components relatively cheap . .Just to confirm.the boiler doesn't make a sound like it fires,then goes out?

no

Ok , if you have a multimeter then you could test the temperature thermostats on ohms ,if not replace the air pressure switch and heating and hot water(best to do both at the same time).
