Mend Vokera Boiler Combi Starts Water

Vokera Boiler Overflow Trouble?

My Vokera combi boiler when turned on starts to push water out of its over flow (outside) and when it stops it needs the pressure topping up.I have checked all the radiators and there are no leaks. This has only started within the last couple of weeks. It works fine apart from that but surely this cant be right.

Any Ideas/Advice please?

thats your prv (pressure relief valve) look under boiler you can see it red knurled knob open and close a few times grit gets stuck in them. if this fails you'll need a new one seals are faulty.
