What to do if your Polaris Tr28P is not working?

If your Polaris TR28P pool cleaner is not working, first check if it gets hung up on steps or other obstacles for longer than 3 minutes. To resolve this, inspect the wheel RPM to ensure it’s within the recommended range, confirm the backup valve is cycling, and adjust the thrust jet. Consider removing excess pool hardware or install a Ladder Guard Kit (part # G21) from a Polaris dealer if needed. If the cleaner is sluggish or has less power than normal, clean the filter screen in the in-line filter, the skimmer basket, pump basket, and pool filter, and check for any leaks in the hoses, connections, and swivels.

Should the Polaris TR28P continue to experience issues, such as not backing up or only turning in one direction, verify again that the backup valve is cycling. Check the wheel RPM, and if the bag is full, empty it. Replace the head float if it has taken on water. Ensure that the feed hose is floating to prevent it from affecting the cleaner’s movement. If the feed hose becomes tangled, remeasure it to make sure it is the right length for your pool, and check that all swivels and connections are turning freely.

For a sweep hose that is being sucked into the vacuum tube or spraying too much water out of the pool, ensure there are no blockages at the end of the hose, adjust it for a gentle motion, and consider adding a sweep hose weight (part #B2) if necessary. To improve overall cleaning coverage, ensure the hose length is adequate to reach all areas of the pool, position the thrust jet for effective turning, and check for consistent water jets when the cleaner is upside down.

Following these troubleshooting steps should help resolve most issues with the Polaris TR28P pool cleaner. If the problem persists, consult the user manual or contact customer support for further assistance.
