Combi boiler leak!!!? The central heat pressure gauge is reading much highly developed than usual...

The central heat pressure gauge is reading much highly developed than usual and there is a steady drip coming from inside the boiler cabinet. Any design?
Answers:    Could be the expansion vessel needs replacing. Call out the manucturer xx
The drip is individual caused by the sanctuary pressure relief tap letting off , this is as a rule rated at 3 pole . you have any let river into the system and not turned it off or a built within pressure reducer is giving trouble , if you can turn off the filler tap to the boiler and then release the pressure via a bleed screw on a radiator , until the pressure compute reads 1.5 to 2 stick , all should be ok but source the sense the pressure increased in the first place , appropriate luck with it.
