Polaris 380 wheels aren't turning - Polaris 380 In Ground Pool Cleaner

My polaris 380 is stuck in backup mode. Fliter screen is fine and wheels do turn.

If your Pol wheel sometimes stops turning and you could force it half a turn to make it go again. Chances are that you have the same problem as mine: HAIR GETS AROUND THE AXIL OF THE DRIVE WHEEL.
This can be fixed by first removing the wheel cap with a flat head screwdriver, then remove the retaining clip that holds the wheel in place. (Be careful not to lose the clip!). Remove the wheel and remove the hair around the axil. Put things back in reverse order. You are set.

I just took my 360 apart. There were broken nylon hose clamps that got into impeller and drive gears. A simple 10 minute fix.

Check for hair on the vertical axel.

If the wheels don't turn there may be sand in the notches on the wheels, the notches may be worn off, if their is sand or dirt in the paddel wheel jet that will keep the unit from turning and again no wheel movement. All of these problems they can check in your local pool store. Stores will generely check your unit out and fix what is needed for just the price of parts to fix it when you bring it into the store.
If you have no water flow to the unit this will also stop things from working so be sure to check your finger screen before you do anything.

Replace the belts.($30) Tighten with an 1/8" play. Also check the wheel bearings. If the wheels wobble they also need to be replaced
