Section 7: Milk System and Refrigeration Unit
3025-007A
Troubleshooting and Repair
Symptom
Cold Milk, No Froth, Milk Overflow
Likely Cause
The regulated air supply from the air-gate valve assembly may not be
present. Airflow into the valve is electronically controlled, and there is
the risk of valve failure. If the valve fails, the result would be similar to
that of a clogged air vent needle. First, change the air vent needle. If
the problem remains, inspect the tubing that connects the air-gate
valve to the milk valve for debris. If neither of these steps resolves the
issue, verify the operation of the air gate valve and repair or replace.
Possible Alternate Cause
The milk valve plunger may be stuck. Check the plunger and lubricate
or replace as necessary.
