Hayward Ecostar VSP Pump won’t start


New member

Equipment: Hayward ProLogic Control Panel and Hayward Ecostar VSP

Drive panel on Ecostar reads drive 0.0 and various other error messages such as “input voltage too low” and “check wiring between drive and display”

ProLogic reads VSP Comm Error. Other functions controlled by the ProLogic still work (pool lights).

After troubleshooting the ProLogic using the technical guides, I thought I had bad rectifiers, but after replacing them, the problem still remains.

Any and all assistance is appreciated!
