Why Pentair Swimming Pool Vacuum Legend® doesn't move?
- S
  Shannon BrownAug 13, 2025
  If your Legend® isn't moving, moves sluggishly, or gets stuck on steps, there are several things to check: * Ensure the filter pump and booster pump are on and working correctly; cleaning your pool filter system might be necessary. * Inspect the Wall Fitting screen for debris and rinse it clean. * Check the wheel RPM. * Make sure the Back-Up Valve is cycling properly by holding it out of the water to see if the jet comes on for about 30 seconds and then shuts off for approximately 3 minutes and 30 seconds. * Inspect all hose connections and swivels for leaks that could be causing a loss of water pressure. * Check for debris jammed in the gear teeth on one of the front drive wheels; gently rotate the front wheels backward to dislodge any debris.

What to do if Pentair Legend LL505G Swimming Pool Vacuum Legend® will not climb?
- R
  Robert ByrdAug 17, 2025
  If your Legend® isn't climbing, try these steps: 1. Brush the sides of the pool wall, even if you don't see algae. 2. Check the wheel RPM. 3. Reposition the Thrust Jet by loosening the two screws to adjust it. Keep in mind that the Legend's climbing ability depends on the pool's shape and water pressure. It climbs better in pools without sharp angles or curves where the floor meets the wall.

What to do if Pentair Legend LL505G Legend® will not back up?
- J
  Jennifer SkinnerAug 28, 2025
  If your Legend® isn't backing up, try the following: 1. Check if the Back-Up Valve is cycling correctly. Hold the valve out of the water; the jet should activate for about 30 seconds and then shut off for approximately 3 minutes and 30 seconds. 2. Check the wheel RPM. 3. Empty the debris bag if it's full or even half full.

Why is my Pentair Legend LL505G Legend® falling over?
- A
  alexisburchSep 1, 2025
  If your Legend® is falling over or lying on its side, it usually means the bag needs to be emptied. Also, check the ballast float (EA20) for leaks by unscrewing it (pull back while turning counter-clockwise), removing it, and shaking it to listen for water inside.

  Mrs. Megan WrightSep 5, 2025
  To prevent hose tangling with your Pentair Swimming Pool Vacuum, consider the following: * Check the length of the Feed Hose, as it might be too long. * Make sure the Feed Hose is floating on the surface and that hose floats are evenly spaced. * Twist the Hose Swivels to ensure they spin freely; replace any that don't. * Lay the Feed Hose straight in the sun to remove any memory.
