Location:
The Dispense Motors are located on the rear of the
platform assembly.
Test Procedure:
1. Turn main water supply off.
2. Gently move motor spade connectors to expose
enough motor terminal for the voltmeter leads to
be applied for DC voltage test.
2. With a voltmeter, install the red lead on the lower
motor terminal and the black lead on the upper
terminal. Pull the coresponding handle. A volt-
age reading between 9.0 to 25 volts dc should be
displayed on the voltmeter. The amount of voltage
is dependent upon the dispense station pot dial
setting.
3. Disconnect the dispenser from the power source.
If voltage is present as described, replace the motor.
If voltage is not present as described, refer to the Wiring
Diagrams and check the pull and hold handle assembly
with reed switch.

1. Disconnect the two wires from the dispense mo-
tor.
2. Loosen the four #8-32 screws securing the motor
to the platform assembly and remove the motor.
3. Inspect the gasket and rubber bushings for signs
of wear and replace if necessary.
4. Position the new motor into place with the gasket
and bushings onto the platform. Secure with four
#8-32 screws previously removed.
