SOURCE: I am wondering in what position should the reverse

You will have some serious problems if you don't put the reverse thruster in the correct position. Be sure to read the instructions carefully. Look at the pictures closely if there are any. Get a magnifying glass to see the detail and position of the part. If not call the toll free number of the manufacturer and ask them exactly what you need to know.

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.

SOURCE: My 4-year old polaris 380 frequently blows

Once you fix the immediate problem with zip ties, check the wheel RPM. It should be between the range of 28 to 32.To check the RPM Hold the cleaner completely under the water and count the wheel revolutions for one minute. If your RPM is to high, you can adjust it at the wall with pressure relief valve by unscrwing it. Im willing to bet your pressure is excessive.

My brand new Polaris 380 booster pump is noisy. What do I do?

Thank you for posting your question here on

It is likely due to cavitation in the booster pump impeller. The easiest way to correct the issue is to slowly close a throttling valve on the booster discharge. If there is not one present install a ball or gate valve near the pump discharge line and slowly close it with everything running until the noise stops. Generally speaking closing the valve about a quarter of the way seems to be when most pumps run quietly but the setting is unique to each installation.

For an impeller really stuck on the motor shaft you need to pull the motor thru-bolts and remove the rotor with the pump still attached from the stator. Lock the rotor in a vice and turn the impeller off with a large set of channel locks or a large strap wrench.

My no flow light is on and the polaris won't move

Not too much to go on but i'll give it a shot. Polaris won't move cause there is no or little water pressure. A number of things can cause this, and i'll give you the most common. Dirty or clogged filter. If it's a cartridge type, remove cartridge and try running without it. Clogged output of pump. No input to pump. Make sure pump is primed.
