Polaris 3900 Sport Questions & Answers
Keeps going in the far left corner - deep end
How can I fix this?
Hi Fran, Mine keeps ending up in the far left shallow!! What I've found is that when the water is cooler, the hose becomes less flexible and the Polaris tends to be less "random" in the way that it moves. I've been trying for 5 years to get it to behave otherwise: changing the pressure-reg, changing the rear jet, changing the whip-tail - nothing has worked. I've put it down to design.
Do you have the "relocator jet" in the hose and is it working? At least this will relocate the cleaner every 5-6minutes to somewhere else....

How hard is it to get to the drive chain? The vacuum seems to be working with the trailing hose swishing around but the wheels no longer turn. This only occurred after I replaced all three tyres a couple of days ago.
When I hold the cleaner in may hands and turn one wheel the others all turn so I would have thought the chain is still engaged correctly but they just do not turn when the cleaner is operating.
Hi Ray, It's not hard to get to the chain - there's about 5 screws you need to undo and the unit's shell comes off exposing the insides. We had the chain in our original unit (purchased 2012) shortened by a few links thanks to a pool-service guy but I think he went a little too far and we ended up with missing teeth on some of the cogs.
The upshot of that was to buy a "tune up kit" like this: external link
The one that I bought had about 20 revised parts in it (maybe there were some v1.0 issues ... perhaps?) It also came with an instruction booklet that gave really detailed steps on how to disassemble and reassemble the unit.
It was interesting because the kit came with basically an new "middle" in which we only kept the hose, wheels and the top cover. The unit has worked much better than before....

Chain came off - I put back on -Will it happen again?
Yes, it will come off every few days. Its a fault I have had for a year now. Polaris rebuilt the inside at my expense but it still does it and it is continually going back to the shop for repairs which do nothing. They just put the chain back on and send it back after 10 days and it throws the chain again. Turn it upside down, spin the wheels and shake it until the chain goes on again and hope it lasts a week.. Good luck with your lemon... I haven't had any with mine.
Hi Rick,
Similar to the post above, it appears that once the chain starts jumping off you can try shortening it (which causes other breakages) or looking in eBay for a "tune-up kit" which replaces the chain and most of the pieces inside the unit.
