The thing I like about the Pentair
Great White and Dorado cleaner is that they have very simple
engineering. Not to say the engineering is not great, just that the
cleaners are easy to work on. The same engineer who designed the
Navigator, Sand Shark and PoolCleaner had his hands on designing the
Pentair Great White.
One of the things I focus on in the
video is that the thin metal piece called the Ratchet Tab. This small
metal piece is what catches on the Ratchet Gear and causes the Cam to
spin. If this Ratchet Tab is bent a little too much outwards it won't
catch on the Ratchet gear and the cleaner will not go into it's turn
cycle. This is probably the main problem you will have with the Great
White or Dorado cleaner.
Simply open the cleaner and bend the
Ratchet Tab inwards so it will catch on the gear. In fact the brand
new Great White I purchased that you see in this video was not going
thru it's turn cycle when I installed it. By bending the Ratchet Tab
inwards I solved the problem and it is working great now. This
Ratchet Tab has to be set exactly at the right angle or the cleaner
will not turn properly. It is not a manufacturing defect but part of
the overall design. A quick an easy fix.
So if your cleaner is not turning check
this Ratchet Tab first as it is likely the source of the problem. Do
this first also before replacing the parts on the cleaner. If your
cleaner is older than 2 years then the gears may also be wearing out
– Specifically the Ratchet Gear that the Ratchet Tab rubs against.
It is a very smart design with only one
set of gears and an Oscillator that moves back and forth, vibrating
and moving the cleaner. So over time the only part that wears out is
the gears that turn the Oscillator. Pentair sells all the gears as a
kit, along with the Oscillator for around $80.00. Once you install
that the cleaner is practically rebuilt.
Here is the link for the Oscilator
Assembly:
There are three more gears that can be
replaced but they are longer lasting than the Oscillator gears and
sit furthur down the shaft. They are called Idler gears and can also
be easily replaced. There are three of them. Here is the link for
those three gears:
The unique turn cycle of the Great
White and Dorado Cleaner is controlled by the Lift Brush that extends
and is controlled by a Cam that spins along as the gears turn. This
Cam has three prongs with different size notches on it. Once it gets
to the large notch the Lift Brush fully extends on the bottom and the
cleaner goes into it's turn cycle. Very original and effective
engineering went into the design of the Cam and Lift Brush. Here is
the link if you need to replace the Cam on the cleaner:
The cleaner comes with a one year
warranty and with regular 8 hour per day use you should get a good 2
years out of most of the parts. Changing the parts is very simple and
the video I filmed should be an easy guide for you.
As time goes on the main Brush Ring
will also wear down. It is easy to replace and is very long lasting.
Think of your pool brush and how long the bristles last on it and you
will have an idea od how long the brush will last on the cleaner.
Here is the link for the Brush Ring:
So that is a quick rundown of the parts
and replacement parts for the Pentair Great White and Dorado Cleaner.
Note that the Dorado has the same internal parts as the Great White.
