OK....... That wasn't what I was talking about but at that time I didn't have numbers to see exactly which hydro pump you have on that unit.
But, I feel this popped valve is your issue...... I suggest cleaning the top of the hydro off real well so nothing drops down into these ports, Then remove both check valves and see if you can then push the popped pin back into place with your finger then perform this test;
If the pin stays down and both pass the spring & leakage test, Re-install and purge as you did before by removing the plug on top......
