it could be your expansion vessel that has split or requires recharging. heat exchanger is blocked or there is an hose connecting the expansion vessel to the pump block. these can become blocked but the hose can be cleaned by using a long thin screw driver to rod it. if u dont know how to check reply back and ill give u some info
