Hi! I'm new here! Here is my issue... I had a 1 speed Hayward pump that died a week ago(probably 10 years old). I went ahead and bought a used Hayward Maxflo Variable pump. I installed it this past weekend and when giving it power it shows on the display Err1 and that's it. The motor does not turn on and nothing else happens. I tried resetting it and nothing. I checked the wiring and everything seems fine. I really have no idea what could be the issue. If anyone has any ideas or suggestions I would greatly appreciate it! Please HELP!!
