Has anyone ever repaired a Pentair VS pump? My VS does not communicate on signal bus, and the manual controls on the pump seem to work fine except that the pump never starts. If I turn it on manually to one of my programmed speeds, it says priming but then fails with an alert. The pump never runs. Is this likely a logic board issue or a pump motor issue? Is there an easy way to bypass the logic board and see if the pump motor works? Any advice would be appreciated!
