ace high combi boiler cutting off ?

[hawkeye29]

Hey guy's , Recently my boiler has been cutting out when i turn my heating on after about 2 mins or whenever it reaches nearly 2 bar on the pressure gauge. The hot water is fine but not sure where to turn next with the heating , any ideas as i'm not the sharpest tool in the box haha.


oh and when it cools down it then fires back up but cuts off again....strange!!


Thanks.

Nothing obvious come to mind and it could well be gas related.

If system pressure is increasing by more than 25% then the expansion vessel needs checking.
