Have a Pentair VF pump and a Hayward Poolvac Ultra
The Pool Vac has worked fine for years with regular maintenance. I have changed all the moving parts several times over the years.
I have a Jandy valve and actuator that switches from the skimmer to the Pool Vac at a specified time. At the same time, the pump switches to 25 gpm. At the conclusion of the vacuum cycle, the pump goes back to "filter" mode, and the valve switches the return from the skimmer.
This setup has worked great for several years. However, recently the pump stalls a few moments into the vacuum cycle. It "reboots" and then a few moments later it stalls again. When I check the suction pressure at the end hose to the Pool Vac, it is in the appropriate range.
Why is this happening? Should I get a new pool vac? Can I program the pump out of it? Any suggestions would be greatly appreciated.
