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).

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
