The Dispense Valves are located at the front of the 

platform assembly.

Test Procedure:

1.  Disconnect the dispenser from the power source.

2.   With a voltmeter, check the voltage across the two 

wire terminals of the valve solenoid. Connect the 

dispenser to the power source. The indication must 

be 24 volts ac.

3.  Disconnect the dispenser from the power source.

If voltage is present as described, replace the valve.

If voltage is not present as described, refer to the Wiring 

Diagrams and check the dispenser wiring harness back 

to the transformer (See TRANSFORMER).

Removal and Replacement:

1.  Disconnect the two wires from the dispense 

valve.

2.  Remove the #6-32 screw and plate securing the 

water manifold tube to the valve.

3.  Loosen the two #6-32 screws securing the valve 

to the platform assembly and remove the valve.

4.  Install the new valve onto the platform and secure 

with two #6-32 screws previously removed.

5.  Inspect the o-ring on the manifold tube connector 

for signs of wear and replace if necessary.

6.  Connect the water manifold tube to the valve and 

secure in place with the plate and #6-32 screw 

previously removed.

7.  Reconnect the two wires to the valve as shown in
