A mate of mine has a problem with his ideal classic ff240 boiler it fires up ok on demand for either DHW or CH although after approx 2 mins the boiler switches its self off and won't restart for a good 5 minutes. Every thing else seems to be working fine ie pump/motorised valve. The flow is starting to heat up prior to the boiler shutting down. Its a sealed heating system and the pressure was about 0.75 bar and when i increased the pressure it shot round to 2.5 bar quicker than you could blink which seemed a bit odd to me. Has anybody got any ideas before calling anybody round.

Try increase the pressure to about 1.5 bar and bleed all the rads make sure the pressure is still correct then try
sounds like a pump problem. probably not rotating fast enough due to wear / crud
the pressure is a red herring as the boiler will still work at zero as there is no pressure switch as it is a heat only boiler or a system boiler if the pressure vessel is on top in a similar box to the boiler
