Since we often get questions about Polaris pool cleaner not moving and not working well enough, we decided to help all the pool owners with this concise Polaris pool cleaner troubleshooting guide.

easy troubleshooting guide for your polaris 360

If you notice your Polaris 360 wheels not turning, (the same goes for Polaris 280 troubleshooting) you should first check that the pressure which comes from your return line is optimal.

If the pressure isn’t strong enough, the problem can be the pool pump, the filter, or the booster pump. Polaris 280 needs a booster pump while 360 and 380 models use the pool circulation pump.

In case you have Polaris 280 not moving, your booster pump could be broken and you’ll need to replace it.

If the booster pump is working properly but you notice air bubbles in your pool, the pool might be getting air in 3 most common places. Find out how to deal with air bubbles in the pool here.  

The 5-Step Polaris Pool Cleaner Troubleshooting Guide

Step 1. Start By Checking The Quick Disconnect

The Quick Disconnect (QD) is the piece which you use to attach your Polaris cleaner’s hose to the return jet. Inside the QD, there’s a screen which catches the debris coming from your pool filter. This screen prevents the debris from getting into your pool cleaner.

The first thing you need to do is to check that the screen has no debris or deposits. If you find it to be clogged, then the screen may be the issue.

Once you clean the screen, make sure it’s not damaged or broken. If it’s broken you need to replace it in order to get the optimal pressure for your Polaris to clean.

Step 2. Check The Hose For Leaks

Another issue causing the problem of insufficient pressure for your cleaner may be a leak in the hose. Make sure there aren’t any leaks in the hose. If you find any, simply replace that section which is rather easy and inexpensive.

Step 3. Check The Backup Valve

The backup valve serves the purpose of creating a strong jet which makes the cleaner move around your pool. This is an important piece of your cleaner which allows it to clean the whole pool and not just one spot.

The valve may be leaking or spraying water so if that’s the case, you need t replace it. They usually last about two years.

4. Check The Drive Belts

Sometimes the drive belts which control the wheels and allow them to turn break and cause your Polaris to stop moving.

To check if the drive belts are the problem, you need to lift your Polaris cleaner off the bottom of the pool and inspect whether all the wheels are turning normally.

If the Back-Up Valve is working, and the tail is moving back and forth, but the wheels are not turning, you should open up the cleaner and inspect the belts. You may find that they are missing. If so, they have snapped. You can buy a new set of belts and replace them yourself, which is quite an easy DIY task.

5. Check the Internal Tubing

The water tubes inside your Polaris direct pressure to different parts of the cleaner. You need to make sure that all the tubes are connected to corresponding hookups. If you inspect the cleaner by taking a look inside, you’ll see if there are any detached tubes.

It’s easy to put the tubes back in place. To make a tighter and more secure connection, you should get plastic hose clamps.

Polaris not working problem (hopefully) solved!

So, Polaris troubleshooting is not that difficult as it usually comes to one of the five things above. If that does not solve the problem of your Polaris not moving, you’ll need to take it to a specialist so he can give it a thorough check.
