1) Place the cleaner on the bench and
examine for physical damage and for any
debris caught in the impeller or drive
brushes (remove debris if found).
2) Place the cleaner upside down on bench
and remove the Bottom id by pushing in
on the red tabs.
3) Perform a Self Test: Plug Cable into the
Power Supply and turn to the ON position.
Important: The Pump Motor will engage
but the Drive Motor will not (An Air Flow
Sensor in the Pump Motor prevents the
Drive Motor from operating out of water).

• If the cleaner is “Dead In ater” or has “No Suction/Does Not Pick Up Debris” then the
unit should not move at all during the self test.
• If the cleaner is “Spinning in Circles” or “Does Not Move” then the impeller should operate
during the self test.

4) Test the voltage through the Power
Supply: Insert the prongs of the voltmeter
into the (2) copper plugs of the Power
Supply socket and turning the unit to the
ON position (29-32Vdc). Picture does not
reflect New Style Power Supply design
but voltage output is the same.
• If Power Supply is found to be defective; replace it with a new Power Supply and perform
another Self Test.
• If Power Supply is found to be OK, proceed with the following steps.

6) Place the prongs of meter into the back
of the Cable harness, connect the other
end of the Cable to the Power Supply
and turn the Power Supply to the ON
position.
Important: eave the Cable plugged into
the Pump Motor for an accurate reading.
• If the voltage drop through the cable is >4Vdc, then proceed to section entitled: Replacing the Cable.
• If the voltage drop through the cable is <4Vdc, then proceed to the next step of the evaluation.
RESULTS
5) Test the voltage through
the Cable: oosen the
pressure fitting to the
Cable and gently pull on
the wires to expose the
connection.

8) Carefully remove the heat shrink covering
the Drive Motor connection.
9) Connect one end of the test cable to the
Drive Motor and the other end to the
Power Supply. Turn the Power Supply to
the ON position.
Important: This is a quick ON/OFF test.
Do Not run the Drive Motors for an
extended period time.
• If the Drive Motor does not turn on or only one side rotates, then proceed to the section entitled:
Replacing the Drive Motor
• If the Drive Motor does turn on, then proceed to the section entitled: Replacing the Pump Motor
RESULTS
7) oosen the pressure
fitting to the Drive Motor
and gently pull on the
wires to expose the
connection.

1) oosen the pressure
fitting to the Cable and
gently pull on the wires
to expose the
connection.
2) Carefully remove the heat shrink covering
the Drive Motor connection.

4) Pull up on the Cable to gain access to
the Strain Relief.
5) Remove the (2) screws that hold the two
halves of the Strain Relief together.
6) Remove the defective Cable from the
cleaner and feed the new cable through
the shell.

Note: There should be at least 14’’ (~35cm)
of Cable inside the cleaner: that is the
distance from the Strain Relief to the
Pump Motor.
7) Find the 14’’ (~35cm) mark and make a
loop in the Cable that intersects with
that line.
8) Take that loop and fold/rotate it down,
so that the free end is to the left.
