    Polaris 3900 left wheel not turning

    My Polaris 3900 is 5 years old. (Yes, hindsight is 20-20) Rebuild by company rep in the spring, new hose, new backup valve. Working so-so since, but just was out cleaning my pool and saw the Polaris goes to the wall and just sets there. Lifted it out and saw the two wheels on the right are turning, the left one dead. The thing just keeps getting stuck on a wall or stair and sitting there. Any advice would be appreciated.

    That could be a bearing issue or a drive axle. Have you attempted to open on the machine? Bearings and axle tend to wear out on a cleaner than age.

    If you need a little help telling what parts are which i found a useful parts breakdown here:

    sounds like the bearing in the wheel itself has chewed out. if so then you will need a new wheel.
