I am on my third Racer also. Have had the tech come out on warranty calls in between also. I have called Pentair direct and they have sent me parts that I installed also. I think every part has broken on the various Racer's I have had. I keep trying to get them to get the new Racer LS for me the next time it needs replacing but tech said Pentair is not shipping yet to the warehouse he gets parts from. I just wonder what they will do once my original 3 year warranty runs out. The good part is when it is fixed and running correct it does a good job. I live on a golf course so I get golf balls in pool. Racer picks those up with no problem.
