My polaris all of a sudden stopped working. On initial exam I noticed one of the wheels was not straight. The bearings seemed to be lose so I replaced both sets on that wheel. I thought that would do the trick, but the sucker won't move. It also lists to one side and doesn't seem to want to stay flat on the bottom of the pool.
Recently my pool guy said my booster pump was leaking...it looks like he replaced the impeller and o-rings.
