Why does my Polaris get stuck longer than 3 minutes on my ladder, including corners, or on other obstacles?

  1. Check that the Polaris 280 is operating at optimal number of wheel revolutions per minute. The optimal range is between 28-34 RPM. It is easy to check the RPM by bringing the cleaner to the edge of the pool while keeping it submerged, turn it so the single side wheel is up. Mark the single wheel and count the revolutions of the wheel for one minute, beginning after the Polaris has completed a back-up cycle (back-up jet off).
  2. Check that the back-up valve (key number 55) is working. Hold the back up valve out of the water and watch that the back-up jet turns on and turns completely off. The jet should remain off longer than its on.
  3. Check the thrust jet (key number 23), it should be in a straight back position.
  4. It may be necessary to install a ladder guard kit (part #G-21) to keep the Polaris 280 from getting stuck on the ladder.

Why does the Polaris sweep hose spray water out of the pool?

  1. The sweep hose scrubber (key number 5) may be worn or missing.
  2. The sweep hose (key number 7) might be operating too fast. The sweep hose should be moving in a gentle sweeping motion. You can adjust the motion of the sweep hose by turning the adjustment screw (key number 10) until it slows down to a gentle sweeping motion.
  3. It might be necessary to add a sweep hose weight (part #B-2) to keep your hose from spraying water.

Why doesn't my Polaris clean the entire pool?

  1. The Polaris 280 cleaner needs to operate at a minimum number of wheel revolutions per minute (RPM). The optimal range is between 28-34 RPM. It is easy to check the RPM by bringing the cleaner to the edge of the pool while keeping it submerged, turn it so the single side wheel is up. Mark the single wheel and count the revolutions of the wheel for one minute, beginning after the Polaris has completed a back-up cycle (back-up jet off).
  2. Verify that the thrust jet (key number 23) is in the straight back position.
  3. If the 280 is still not covering the entire pool you will need to make sure your feed hose is cut properly.
  4. Check the feed hose float placements.
  5. Check that all wheels are turning when in operation.

Why does the Polaris 280 not climb the walls?

  1. Check that the Polaris 280 is operating at optimal number of wheel revolutions per minute (RPM). The optimal range is between 28-34 RPM. It is easy to check the RPM by bringing the cleaner to the edge of the pool while keeping it submerged, turn it so the single side wheel is up. Mark the single wheel and count the revolutions of the wheel for one minute, beginning after the Polaris has completed a back-up cycle (back-up jet off).
  2. Verify that the thrust jet (key number 23) is in the straight back position.
  3. Check that the head float (key number 4) should be pushed to within one inch of the feed mast (key number 11).
  4. The idler wheel (key number 24) is responsible for driving the back wheel. Push down on the idler wheel to dislodge any sand or dirt.

My Polaris runs on its side.

  1. Check that the filter 280 bag (key number 1) is not full of debris. Be sure to empty the filter bag regularly.
  2. Check that the head float (key number 4) is not filled with water by removing it from the cleaner and shaking it. If there is water in the float, replace it.
  3. Check that the hose floats (key number 51) are floating and are spaced properly on the feed hose (key number 52) .

The 280 feed hose keeps tangle and tying itself in knots.

  1. Check that the Polaris 280 is operating at optimal number of wheel revolutions per minute. The optimal range is between 28-34 RPM. It is easy to check the RPM by bringing the cleaner to the edge of the pool while keeping it submerged, turn it so the single side wheel is up. Mark the single wheel and count the revolutions of the wheel for one minute, beginning after the Polaris has completed a back-up cycle (back-up jet off).
  2. Check the hose length and float placement.
  3. Check the hose float placements.
  4. Check that the back-up valve (key number 55) is working. Hold the back up valve out of the water and watch that the back-up jet turns on and turns completely off. The jet should remain off longer than its on.
  5. Check the swivels on the feed hose, each should turn freely and the flow arrows must be pointing toward the cleaner.

Why does the Polaris 280 fly through the water, not touching the bottom?

  1. Check that the back-up valve (key number 55) is working. Hold the back up valve out of the water and watch that the back-up jet turns on and turns completely off. The jet should remain off longer than its on.
  2. Check that the head float (key number 4) is not filled with water by removing it from the cleaner and shaking it. If there is water in the float, replace it.
  3. Check that the head float should be pushed to within one inch of the feed mast (key number 11) .
  4. Check that the Polaris 280 is operating at optimal number of wheel revolutions per minute. The optimal range is between 28-34 RPM. It is easy to check the RPM by bringing the cleaner to the edge of the pool while keeping it submerged, turn it so the single side wheel is up. Mark the single wheel and count the revolutions of the wheel for one minute, beginning after the Polaris has completed a back-up cycle (back-up jet off).

Why does the Polaris move slowly?

  1. Check that the Polaris 280 is operating at optimal number of wheel revolutions per minute. The optimal range is between 28-34 RPM. It is easy to check the RPM by bringing the cleaner to the edge of the pool while keeping it submerged, turn it so the single side wheel is up. Mark the single wheel and count the revolutions of the wheel for one minute, beginning after the Polaris has completed a back-up cycle (back-up jet off).
  2. Check the filter screen (key number 46) in the quick disconnect.
  3. Check that the feed hose nuts and swivels are not leaking any water. If they are leaking, tighten the hose nuts, or replace them.

The feed hose does not stay connected to the Universal Wall Fitting.
