AYC Pressure issue

Hi, I've come across a problem I haven't experienced before with an AYC pump. It builds pressure but it won't hold it. It did initially hold at 10bar.

I've changed out the accumulator and drained and bled it twice. I'm just wondering if something has lodged something open internally.

I'm just about to open it up again but any ideas would be great.

Thanks

10 bar is too low... the pump is probably failing..

Looks like the PRV was initially stuck shut, was going off the gauge. Then it must have got wedged open as didn't build pressure as above 15bar, just sat there with motor running. Stripped and cleaned. PRV pops opens at 15bar and pump holding 13bar pressure now.
