This sounds unusual to say the least. I assume you are hearing normal pump sounds throughout? Are you seeing release of water from the exhaust valve during the shot or excess flow of water back from the OPV to the tank?
Items which initially come to mind are pump or pump solenoid issues- these are extremely rare. It may be a sticky OPV and if so, youd see excess water back to the tank. A descale may help but it might require disassembly to clean it or replacment.
I have asked the guys at ECA to also look over your post for comment and hope we have a rapid diagnosis for you.
