Problem
WATER LEAKS FROM
BOTTOM OF DISPENSING
VALVE.
WATER CONTINUOUSLY
DRIPS FROM NOZZLE.
UNIT CONTINUES TO
DISPENSE AFTER BUTTON
HAS BEEN RELEASED.
TWO OR MORE PUMPS
OPERATE WHEN ONLY
ONE BUTTON IS PUSHED.
Troubleshooting Guide
Probable Cause
Nozzle pieces improperly
assembled.
Water solenoid valve not
shutting off tightly.
Inoperative or defective push
button switch, or portion
control board.
Relay on voltage regulator
board hangs up or is stuck
open.
Defective Voltage Regulator
(VRB) Board.
Insulator pad missing or not
properly positioned between
the transistor on VRB board
and mounting bracket.

Remedy
Static mixer inserted in nozzle body
upside down. Cone shaped end must
be visible when remounting the
nozzle assembly to the dispenser.
Disassemble water solenoid located
at the valve and check for foreign
material in the valve seat. Check the
armature for binding, check the
plunger and the seat for defects.
Replace parts as needed.
Check the operation of the push
button for sticking. Check continuity
of switch. Replace as needed.
CAUTION: Access to this panel
requires removal of the bonnet while
the dispenser is plugged in and
operational. *Voltage regulator board
is found in the electrical box mounted
to the refrigeration deck. There is one
board for each valve. Gently tap the
relay. If dispensing stops, relay was
hung up . If tapping the relay solves
the problem, it should be noted that if
a relay sticks once , it will probably
stick again. Replace as needed.
Pull the connector marked DOOR ,
lower right hand connector on the
VRB board. If the unit still continues
to dispense the VRB board is
defective and needs to be replaced.
On the valve that is dispensing in
error, check the insulator pad
between the transistor on the top of
the VRB board and the mounting
bracket. If this pad is missing or
improperly aligned, the VRB board
will make contact with the bracket.
Current will run through the bracket
and set off the valve. Refer to
drawing found in this manual.
