the hot water works fine, but the heating doesn't. when i press the reset switch on the front it displays ' co ' and the heating comes on then stays on which is fine, but the pressure display goes up to 3bar . when i press the switch again it turns off and the heating wont turn on. help

My boiler was flashing code 07 Primary Thermistor open circuit. I replaced the switch as described in the installation and servicing instruction manual. I then refilled the system so the pressure gauge read 1.5 bar. After half an hour the pressure went down to 1 bar. I then refilled the system to 1.5 bar and left it overnight and subsequently when checking the pressure the following morning it had gone down to zero. Hope this helps.

the operating pressure should be 1 to 1.5 bar MAX. There is a built in safety valve that operates if the boiler pressure exceeds 3ba.

My Vokera Compact 24 boiler had high pressure problems. they were cured by adding a new expansion vessel and disconnecting the old one. It may be worth trying to re- charge the pressure vessel, but if it loses pressure again then replace it
