Your Polaris pool cleaner won’t move. It’s like a rock sitting at the bottom of your pool. Or maybe it is just sluggish. Either way, it is not moving like it is supposed to be moving.
The bad news: There are a lot of things that could be causing your Polaris to be so lifeless.
The good news: It is not too hard to find out which of these many things is causing the problem.
Start at the wall
The easiest way to check why your Polaris is not moving is to go down the line start from the wall. The first thing to do is unscrew your universal wall fitting from the wall. If you are getting water coming from the line that is in the pool wall, then you problem lies somewhere in the Polaris. If you are not getting flow through the wall, don’t worry – your blog post is coming.
If you are getting flow from the wall, you should first check the universal wall fitting that you just unscrewed. The most common cause of lost pressure in this is from the pressure relief valve.
This small piece is meant to vent excess water pressure. The spring will stretch or contract to keep just the right amount if water going to your Polaris. if there is too much water getting to your Polaris, it will simply fly around the pool without touching the bottom that it is supposed to be cleaning. If the spring is staying extended, however, all of your water will leak out here.
If while your cleaner is on and in the pool, you can feel a forceful stream of water coming out of the pressure relief valve, it is time to replace it. (note: the 360 uses its own pressure relief valve, 9-100-3009)
The Polaris moves because there is water getting to it and pushing it. If there is no water getting to it, then it is not going to move. This is important to keep in mind when you are troubleshooting your Polaris pool cleaner.
What carries water to the cleaner? The hose! It is not hard to let a small crack or leak go unnoticed. So check your feed hose for both cracks and leaks along its connections. Replace anything that is leaking water.
The Backup Valve
Along the hose is the Polaris G-52 backup valve. It looks like:
This valve is meant to keep your cleaner from getting stuck it corners (it “backs them up”). To do this, it cycles on and off every four to six minutes. If it stays on never cycles off, however, what you have is basically a huge leak in your line. you should get a new Polaris backup valve. (Again, the 360 has its own backup valve, the 9-100-1200.)
If it’s not the UWF, the hose or the backup valve, the problem probably lies with the cleaner. The first thing to check is the wheels. Can you spin them by hand? If you spin one, will the rest spin? If the answer is no, then you will need to dig deeper, because some thing is wrong. You might need to replace your Polaris wheels, axles or other parts of the drivetrain.
If you can spin the wheels, check the sweep hose (the tail at the end of the Polaris). If it is whipping back and forth wildly, there may be too much water getting to it. there is a sweep hose adjustment screw. Screw this in more to redirect the water from the sweep hose to the actual movement of the cleaner.
If this is not solving your problems, the last place to check is the drivetrain on the inside of the cleaner. If there are any jams or leaks here, your wheel will never have a chance of turning.
When your Polaris pool cleaner is having mobility issues, it is not too hard to find out what is wrong. It is just a matter of following where the water goes.
