vokera mynute 20e. pressure goes to three bars and continues to rise when boiler is left on. I have bled the rads and this has made no difference. i have replaced a noisy acuator and problem is still there.
If boiler only increasing in pressure when heating is on then your expansion vessel is burst or needing recharged. If increase in pressure when boiler is off then filling loop passing.
