Empty Spa - Automatic Valve is Not Moving

I have what I believe is a Pentair Automatic Valve.

This morning I woke up to an empty Spa, it drained into the pool and the pool was off. This happened once before around 1.5 years ago. When it happened last time I could manually trigger the ON1/ON2 Lever and it fixed the issue.

This time the ON1/ON2 Trigger did not do anything. I opened the cover removed the nuts/washers (circled in pic 2) and then ON1 moved the valve, ON2 did not do anything. As expected, the Spa refilled when I turned the pool back on. If the nut/washers are back in place then ON1 no longer moves the valve.

Any idea how I can permanently fix this?
