The cleaner was working fine and then left wheel stopped working but the main motor and the right wheel continued to run. I put it back in the pool and it started to run fine but then the left wheel quit again. The controller puts out 29 v and there is continuity in the main chord.The controller when plugged in now goes to flashing red lights.
