I have an old Great White that was working fine until it decided to keep rotating. I noticed that the brush would come out and not retract, causing it to go into an endless pivoting.
After replacing gears and disassembling and reassembling everything several times, I gave up.
I bought a used Kreepy Krauly on ebay with an opposite problem: it would just go straight, as the brush would not come out.
I then used the best parts of the two cleaners to make one. I put it together and it worked perfectly... for 2 days.
It started the endless rotating cycle. I swapped a few parts again and sometimes it would work fine for about 10 minutes and then fail again.
I noticed that when the brush is stuck out, if I lift the cleaner a little bit, the brush would retract, what made me wonder if there was too much down pressure, preventing the brush to move. I experimented reducing the flow to the cleaner, to reduce the pressure and the vacuum, but it did not help.
Playing with it out of the pool and with the hood off, I see that if I press the cleaner down, the gears do not have enough "power" to continue moving and get stuck. Therefore, the brush cannot be released to retract.
Any suggestions on how to fix it?
Thank you in advance!
