Question about Polaris 380 In Ground Pool Cleaner

1 Answer

The jets in the water management system don't seem to be working. There is little or no water flowing into the bag. The wheels move and there is backflow, but the inside jets aren't working well.

I have the same issue, I have been told to replace the water management system. You can get a new one for under $30 on ebay.

Polaris 280 moves around pool ,screens not clogged water still spraying up toward bag but not picking anything up


Hi, even though the two jets appear to be spraying upwards, the force may be diminished by partially blocked nozzles. To check remove the debris bag and observe jet action as cleaner is held near water surface. the action must be strong enough to shoot well into the air. If not, then often a piece of wire can be inserted into jets to dislodge the debris. you may have to do this one or more times.
the other cause of insufficient jet pressure is that the feed hose to jets has ruptured or the zip strip retainer has broken. unit must then be partially disassembled.

Not enough flow and pressure to run sprinkler system


pressure in centrifugal pumps depends on the number of impellers in the pump housing, the clearance of the impellers to the housing and the power of the motor to drive the impeller/s
volume flow is also important as a pump without a high output will not produce pressure
check the jet size at the foot valve that is used to help lift water to the pump
It is a jet pump and will have a smaller line back to the foot valve for that purpose
next wil jet pumps if there is too much flow to the outlet , the pressure required to help lift the water to the pump is reduced and the volume is also reduced
you indicate 4 sprinkler heads per zone but how many zones are operating at one time
check the expected delivered volume for the new pump against delivered volume of the old pump as a starter to find the reason for the poor performance of the new pump
check also the rpms of each pump as that also has a bearing on volume produced

How many jets does the 380 have that may need to be cleaned, I see 3


It sounds like you have a clogged drive turban jet or an internal hose has popped loose. I normally tell people to double check the backup valve to verify that it has been installed the right way (widest part toward the wall,)
There is a total of 6 jets, three vacuum jets blow debris into bag, one thrust jet bows water out of the nozzle on back of unit, one drive jet that operates the drive gears and one operates the sweep tail.
It is best to disassemble down to the "water management system" listed above and rinse well, shaking it in all directions. Any small debris can clog the jets, including ants!

My polaris 280 moves around just fine and the sweeper hose is functioning properly. only issue is that it's not sucking anything up in the bag.


This can be caused by either by minimal or no water being delivered by the vacuum jets or something plugging the path to the bag. I assume you have checked the path to the bag so it is probably the first cause. The best way to check this is to turn the pump on while the cleaner is in the pool, pull the cleaner to the side of the pool, pinch off the hose just before the backup device and lift the cleaner onto the deck. Some water should be coming out of the rear jet and the tail. If you remove the bag and look down through the cleaner you should see the two jets that shoot water up. If you stand back and unpinch the hose and the water doesn't come up way above where the top of the bag would be then either you have plugged jets or the hoses inside the cleaner are disconnected. I suggest the latter because if the jets were plugged I would expect the jet that turns the wheels would be plugged also. If you don't feel competent taking it apart then bring it to Leslies Pool Supplies and they usually can open it up while you watch and repair it for the cost of parts. By watching them you may learn enough to be able to do it yourself the next time. I hope this helps.

If all the belts, bearings, shafts, etc are in order and the wheels don't turn then the turbine is not providing power to the system. This turbine is under a cover inside the cleaner. Remove the cover to inspect it (look for any mechanical problems). You can also connect water pressure to it at this time to see if the jet that turns it will make the turbine turn. If the turbine is being hit by a jet of water it should turn if the friction in the belts, bearings, shafts, etc. is not too high.

Hi, Emil_hugo if you have changed your fuel delivery system, air filter size or flow rate, mufflers or exhaust system or a significant change in altitude your carburetors need re-tuning and if your fuel system (gas tank, filters, fuel valve and carburetor) is contaminated with ethanol sludge, varnish, rust, dirt, water etc. or your bike has been sitting for months or years without running these components must be "PROPERLY" cleaned and reassembled "CORRECTLY" before any adjustments can be made. Tuning your carburetor is fairly simple once you understand the basic principals. You engine is a simple airbox sucking air in and blowing it out, it is finely tuned at the factory for maximum performance once you upset that delicate balance by changing air filters, camshafts or exhaust systems your performance may go down the and the engine may run poorly, you need to compensate the air-fuel mixture in the carburetor in order for the engine to run smoothly and at peak performance. If you are running multi carburetors you need to sync them first and make sure your air cleaner element is clean and dry for paper elements or lightly oiled for foam and meshed elements and properly installed. Here is how and where you compensate trouble: "TIP" if your engine "BOGS" your not getting enough fuel or air.
1. Closed to 1/8 throttle is managed by the air screw and pilot/slow jet.
2. 1/8 to 1/4 throttle is managed by the air-screw, pilot/slow jet, and throttle slide.
3. 1/4 to 1/2 throttle is managed by the throttle slide and jet needle.
4. 1/2 to 3/4 throttle is managed by the jet needle, needle jet, main jet, and air jet.
5. 3/4 to wide open throttle is managed by the main jet and air jet.
6. Wide open throttle is managed by the main jet.
If you are running lean, spark plug electrode color is white, engine runs hot and feels like it is starving for fuel you need to go up on the jet size or move the c-clip down one notch. If you are running rich, spark plug color is black or dark gray, engine runs cool, and bogs down when accelerating you need to go down on jet size or move the c-clip up one notch. When your carburetor is properly tuned for maximum performance your spark plug electrode will be a light tan color like coffee with cream. If you prefer fuel economy over performance you can go down on main jet sizes until a satisfactory level of lower performance is acceptable versus MPH, your spark plug color will be whiter and your engine will run warmer. These tuning adjustments will only make improvements if your intake and exhaust system have no air leaks or sealing issues and the entire electrical system is in proper working order and you have no mechanical issues.

I purchased a Polaris 3900 on 6/2/2010 and have already replaced two filter bags. Both times the bag has become wedged between the chasis and the wheels tearing the bags. Any suggestions?


First, make sure that the velcro closure on your pool cleaners bag is sealed tightly. If the velcro is coming lose, it could be the problem. Next, make sure that your wheels are operating at the proper RPM. Too little RPM could cause the pool cleaner to be sluggish and not create the proper tension to keep the bag floating. It should be between 30 and 36. If it is running at less than 30 RPM, there are few things that you can do to fix it. If an adjustable valve is installed on the cleaner line, open it completely so water can flow freely to the cleaner. Check the filter screen in the in-line filter
for debris that restricts water flow and clean if necessary. Also clean the skimmer, filter, and pump baskets. Check the hoses, connections and swivels for leaks that cause loss of water pressure. Finally, if none of these solutions work, remove the blue restrictor disk from the UFW.

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
