When I plug in my pump it either tries to start and then shuts down with message FAULT 12 REMOVE POWER AND CHECK IMPELLER SIZE or it starts for a few minutes (varies) then stops again with the same message. Was running fine until today. Impeller nut turns easily by hand. What does this mean?
Getting error message on screen for 2 speed 1 hp pump from inyo.
