I have a 2-year old Ecotech variable speed pool pump motor that just failed. The run/start button flashes green continuously and the other buttons and the display do not work. I tried a factory reset and power cycling, but that did nothing. The shaft turns freely when disconnected from the pump, so I am thinking it is an electronics issue. Does anyone have experience in repairing these units? Already tried Nidec (formerly Emerson) and the place where I bought the pump, but both were unhelpful.
