I have a 5-year-old Superflo VS. It primes for five minutes, then runs at specified lower speed for an hour or so, then restarts, reprimes, runs again for a while, then stops with Error Code 1A. My pool guy says I need new motor, Pentair Customer Support says it's a Drive problem. I've read that it might be a motor issue, but the motor's not shot. Dunno whether to replace the motor, or the Drive, or what.
