| Problem | Cause | Solution |
|---|---|---|
| The Pentair Racer LS cleaner doesn’t move or moves slowly. | Filter or booster pump issues, debris in wall fitting or in-line filter, incorrect flow, leaks in hose connections, debris in gear teeth, rear wheels not spinning freely, backup valve not cycling. | – Ensure filter pump and booster pump are on and moving water; clean pool filter system if necessary. – Clean wall fitting and in-line filter debris screens. – Adjust flow by calculating cleaner speed/RPM and adjust at the wall fitting. – Check hose connections and swivels for leaks. – Clear debris from gear teeth by rotating front wheels backward. – Check rear wheels and replace if they do not spin freely. – Ensure backup valve cycles every 3-1/2 minutes to reposition the cleaner. |
| The Pentair Racer LS cleaner hangs at steps. | Backup valve not cycling properly, incorrect flow. | – Ensure the backup valve cycles every 3-1/2 minutes. – Check for proper flow by calculating cleaner speed/RPM and adjust at the wall fitting. |
| The Pentair Racer LS cleaner tilts to one side. | Full debris bag or part of its normal operation during a turn cycle. | – Empty the debris bag if it is full. – Observe the cleaner for a few minutes to see if it repositions itself upright. |
| The Pentair Racer LS cleaner does not go in reverse. | Backup valve not cycling properly, incorrect flow, debris in wall fitting or in-line filter. | – Ensure the backup valve cycles every 3-1/2 minutes. – Check for proper flow by calculating cleaner speed/RPM and adjust at the wall fitting. – Clean debris screens in wall fitting and in-line filter. |
| The Pentair Racer LS cleaner will not climb. | Full debris bag, incorrect flow. | – Empty the debris bag if full. – Check for proper flow by calculating cleaner speed/RPM and adjust at the wall fitting. – Note that climbing ability varies with pool shape and water flow. |
| The Pentair Racer LS hoses tangling in loops. | Hose length too long, hose floats misplaced, swivels not spinning freely, kinks or bends in hose. | – Adjust the length of the feed hose. – Ensure the hose floats are spaced correctly. – Replace swivels if they do not spin freely. – Straighten out any kinks or bends in the hose. |
| Booster pump very noisy. | Filter or booster pump issues, leaking wall fitting. | – Ensure filter pump and booster pump are on and moving water; clean pool filter system if necessary. – Check wall fitting and replace O-Ring if leaking. – Consult a pool professional for booster pump issues. |
| The Pentair Racer LS Rear wheels dragging/not spinning. | Tangled debris. | – Ensure the wheel is free of tangled debris. |
