How to Diagnose and Repair a Pentair Racer LS

This guide will help you identify and resolve issues with your Pentair Racer LS Pool Cleaner.

Why Doesn’t the Pentair Racer LS Cleaner Move or Moves Slowly?

If your Pentair Racer LS cleaner is not moving or is moving slowly, it could be due to filter or booster pump issues, debris in the wall fitting or in-line filter, incorrect flow, leaks in hose connections, debris in the gear teeth, rear wheels not spinning freely, or the backup valve not cycling. To resolve this, make sure the filter pump and booster pump are on and circulating water, and clean the pool filter system if needed. Clean the debris screens in the wall fitting and in-line filter, adjust the flow by calculating the cleaner speed/RPM and adjusting at the wall fitting, check hose connections and swivels for leaks, clear debris from the gear teeth by rotating the front wheels backward, check the rear wheels and replace them if they do not spin freely, and ensure the backup valve cycles every 3-1/2 minutes to reposition the cleaner.

What to Do If the Pentair Racer LS Cleaner Hangs at Steps?

If the cleaner gets stuck on the steps, it might be due to the backup valve not cycling properly or incorrect flow. Ensure that the backup valve cycles every 3-1/2 minutes and check for proper flow by calculating the cleaner speed/RPM and adjusting it at the wall fitting.

How to Fix the Pentair Racer LS Cleaner Tilting to One Side?

The cleaner tilting to one side could indicate a full debris bag or be part of its normal operation during a turn cycle. Empty the debris bag if it is full and observe the cleaner for a few minutes to see if it repositions itself upright.

Why Does the Pentair Racer LS Cleaner Not Go in Reverse?

If the cleaner does not go in reverse, this could be due to an improperly cycling backup valve, incorrect flow, or debris in the wall fitting or in-line filter. Ensure the backup valve cycles every 3-1/2 minutes, check for proper flow by calculating the cleaner speed/RPM and adjust at the wall fitting, and clean the debris screens in the wall fitting and in-line filter.

What to Do If the Pentair Racer LS Cleaner Will Not Climb?

If the cleaner is unable to climb, it may be due to a full debris bag or incorrect flow. Empty the debris bag if it’s full and check for proper flow by calculating the cleaner speed/RPM and adjust at the wall fitting. Note that the cleaner’s climbing ability can vary with the pool shape and water flow.

How to Address the Pentair Racer LS Hoses Tangling in Loops?

If the hoses are tangling in loops, the hose length might be too long, the hose floats could be misplaced, the swivels might not be spinning freely, or there could be kinks or bends in the hose. Adjust the length of the feed hose, ensure the hose floats are spaced correctly, replace swivels if they do not spin freely, and straighten out any kinks or bends in the hose.

What Causes a Noisy Booster Pump?

A noisy booster pump could be due to filter or booster pump issues, or a leaking wall fitting. Make sure the filter pump and booster pump are on and circulating water, and clean the pool filter system if necessary. Check the wall fitting and replace the O-Ring if it’s leaking. If the problem persists, consult a pool professional for booster pump issues.

How to Fix the Pentair Racer LS Rear Wheels Dragging/Not Spinning?

If the rear wheels are dragging or not spinning, it could be due to tangled debris. Ensure that the wheels are free of tangled debris, which may require cleaning or removing any obstructions.
