Polaris P39 Troubleshooting

The Polaris P39 cleaner hangs up on steps or other obstacles for longer than 3 minutes

Solution:

1. Check the wheel RPM.
2. Verify the back-up valve is cycling.
Lift the valve out of the water and watch the jet. It should come on and go off.
3. Adjust the thrust jet.
4. Remove unnecessary pool hardware or install a Ladder Guard Kit (part #G21).

The Polaris P39 cleaner is sluggish, running with less power than normal

Solution:

1. Check the filter screen in the in-line filter assembly and clean if necessary.
2. Clean the skimmer basket, pump basket, and pool filter.
3. Check the hoses, hose connections, and swivels for leaks that could cause loss of water pressure.
4. Check the wheel RPM. If below 30 RPM, see Adjusting the Wheel RPM to increase flow to cleaner.

The Polaris P39 cleaner races around the pool and/or does not make contact with the pool bottom.

Solution:

1. Check the wheel RPM. If more than 36 RPM, see Adjusting the Wheel RPM to reduce flow.
2. Verify the back-up valve is cycling. Lift the valve out of the water and watch the jet. It should come on and go off.

The Polaris P39 cleaner doesn’t back up

Solution:

1. Verify the back-up valve is cycling. Lift the valve out of the water and watch the jet. It should come on and go off.
2. Check the wheel RPM. If not in 30-36 RPM range, see Adjusting the Wheel RPM.
3. If the filter bag is full, empty or replace it.
4. Make sure feed hose is floating.

The Polaris P39 cleaner only turns in one direction

Solution:

1. Adjust the thrust jet.
2. Make sure feed hose is floating.

The Polaris P39 feed hose becomes tangled

Solution:

1. Remeasure the hose to verify that it is adjusted to the proper length for the pool.
2. With the cleaner operating, check that the swivels and hose connections turn freely.
3. Make sure the feed hose is floating.
4. With the Polaris operating, hold the cleaner under water and verify that all three (3) wheels are turning together.

The Polaris P39 front end of the cleaner lifts all the time

Solution:

1. Check the wheel RPM.
If not in 30-36 RPM range, see Adjusting the Wheel RPM.
2. Adjust the thrust jet downward.
3. Verify the back-up valve is cycling.
Lift the valve out of the water and watch the jet. It should come on and go off.
4. Check for water inside the cleaner float.

The Polaris P39 sweep hose is sucked into the vacuum tube

Solution:

1. Make sure the opening at the end of the sweep hose is not blocked by the sweep hose scrubber. Replace scrubber if it is worn or missing.
2. Adjust the sweep hose to a gentle sweeping motion.
3. Check the wheel RPM. If more than 36 RPM, see Adjusting the Wheel RPM to reduce flow.
4. Add a sweep hose weight (part #B2).

The Polaris P39 cleaner does not clean the
entire pool

Solution:

1. Verify that feed hose reaches within 6 inches of the farthest point of the pool. If not, order a new hose section from your Polaris dealer.
2. Adjust thrust jet to improve coverage.

The Polaris P39 cleaner is running in circles on
its side

Solution:

1. Check for water inside the cleaner float.
2. Check the filter bag, if full it can weigh the cleaner down on one side.
3. Check the hose floats to make sure they are spaced evenly.
4. Check the wheel RPM. If more than 36 RPM, see Adjusting the Wheel RPM to reduce flow.
