Sounds like the expansion vessel needs recharging.

Look in the FAQ section.

Look in FAQ to see how to check and repressurise expansion vessel.

Could be a faulty filling loop, Disconnect, close valve off and check for leakage. also check the boiler vent , maybe a blockage which would also cause pressure increase.regards chrisey.

If you press down on the tyre type valve on the expansion vessel and water comes out it is totally knackered.
