Hi
Probable cause can be one of the following
Pressure reducing valve, in this case you need to replace multifunction valve as it's a built in component
Or cold water expansion vessel has ruptured which also needs replacing
Hope it helps

If it has happened before, then i would suspect either your white expansion vessel needs recharged (usually to about 3 bar) or it has ruptured inside and would need replaced
