SOURCE: Polaris 380 wheels not moving

Here are some things to check: 1.  There are belts inside the unit that drive the wheels.  These belts often fail (shred) and must be replaced. 2.  There is a paddlewheel that drives the turbine that turns the wheels.  If the jet that drives the turbine is clogged, then the paddlewheel will not move and the wheels will not turn. 3.  There is a water management system inside the bottom of the unit.  It looks like a bunch of little hoses.  If one of these hoses comes loose, then the water pressure will escape inside the unit and will not be sufficient to drive the wheels.
Hope this helps

SOURCE: My polaris 380 wheels won't turn. the belt is

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.

The PB4-60 doesn't fit

They changed the design of the pump a few years ago when Zodiac bought out Polaris. Re-plumbing isn't that hard to do, but if you are not comfortable with it a pool tech or handyman should be able to do it for about $60.

Impeller rubing on the housing after motor starts.

The motor bearing on the pump end may have failed. Looks like this pump cost about $200 so having it inspected and repaired may be close to that. Unless you know someone who works cheap or you have some mech abilities. Here is a link to an exploded assembly parts drawing.

When I turn on the power, my polaris pb4 pol pump buzzes for a few seconds and then stops and doesn't do anything,

Check for a jammed impeller in the pump. Otherwise, sounds like the capacitor is probably bad. Either in a raised housing on the outside of the motor or in the back under the motor cover. The capacitors are rated in uF or micro farads. Be sure to get the right one...

The hose connected on the interior of the polaris could be disconnected. seperate the housing and you will see the hose. Or you need more pressure at the wall. Try closing are reducing the amount of flow to the skimmers to up the flow at the wall connection. Your back up valve should pull the polaris off the steps. Set the rotating jet propulsion on rear to 11: 00 position.

Polaris hangs in the deep end

Check to see if one of the drive belts is broken. You'll need to pull the wheels and separate the housing to inspect. Also make sure that the thrust jet is centered and pointing towards 12:00. This unit should back up after 3 minutes and reposition itself.
