Hayward AquaVac 250Li Pool Cleaner Not Working?

If you're experiencing issues with your Hayward AquaVac 250Li pool equipment, you're not alone. Many users have faced similar challenges and have shared their experiences to help others troubleshoot and resolve these problems.

  4. AquaVac bumps into wall and only reverses course 10-20% of the time. I have a 24 ft round pool and have tried various combinations of trajectory settings. It reverses course if I manually move paddle but should do it automatically. Please help.

  5. Have charged and used mine a few times this year. I recharged it and it shows full charge, but when I put it in the water the unit will not turn on and the lights go out. I am assuming that the battery is defective and not holding a charge, but I bought this only 1 year ago and have used it less than 10 times.
