The internal cassette of our Zodiac Barracuda G4 unscrews itself from the hull each day. each day we have to screw the cassette back into the hull. This has happened occasionally in the past but now it happens every day. What is causing this?

I put several layers of Teflon tape on the threads in hope this will solve this problem. My barracuda G4 is several years old and just started doing this in 65 degree pool water. The cold could be causing some shrinkage So far it has helped.

Try wrapping white plumbers tape around the threads 3 or 4 times and then screw back together. That worked wonders for me when i had that problem.

That's how they run, they basically just follow their hose!

Try your local pool shop.

Sorry, but none of you are actually answering the question. I have the same problem (but with the pacer).
The main internal body of the cleaner, (that houses the diaphragm) keeps unscrewing itself and the inner part is the free to pulse (from the full functional diaphragm) in place, because the pulse generated by the opening and closed diaphragm isn't now able to jolt the outer body and therefore move it around the pool.
There is noting wrong with the diaphragm and nothing lodged inside it.
Does anybody have an answer for *that*?

Keep in mind that they are made of plastic and the threads change shape over the years.. Try applying several wraps of Teflon tape on the cassette threads and re tighten. This should keep from unwinding... Good luck and hope this helps you... If helpful, please take the time to write a comment and rate,,

Try some teflon tape.. Remove the cassette and apply 3 to 5 even wraps on the thread and then install the cassette back on and tighten.. This should keep the neck from backing out...

You can check your water flow and make sure that it is not too high, but if your pool cleaners flipping over, there is probably a rather sever issue. Zodiac recommends that you contact your local warranty location if the cleaner is still under warranty.

The best way to install the foot pad is to the install the flat part of the cassette to feed the foot pad into the grove (as you turn it). It always always works best when warm, so if the foot pad has been out side and it is cold, then it will need to warm up.

When the foot pad finishes, the flat part will be towards the back and the rounded part towards the front of the cleaner.

INSTRUCTIONS FOR REPLACING THE FOOT PAD

Unthread and remove the cassette. Holding the Baracuda G3, press down on the yellow clip while pulling the foot flange toward you. Pull off the old footpad and stretch on the new one. Insert the locking clip of the foot flange into the large opening, push forward to lock into place insert the cassette and tighten.

add a little silicone to the threads and wait a couple of hours then use. also you might try some teflon.
