Check BIB connector for proper
installation. Plunger should be
completely inserted with concentrate
filling the line to the dispenser.
Check the 3/8 flare connection where
the product line attaches to the unit.
Tighten fitting using a flare gasket. If
line is drawing air, pump will not
prime.
Check for broken or loose wire
connection going to pump motor.
Check for 26 VDC at pump motor
when the dispense button is
energized.
Check motor function by energizing
circuit with the dispense button. If
motor runs, but pump does not turn,
a broken gear box is indicated. The
pump motor and gear box are
replaced as a unit.
Check the direction of pump
rotation...correct rotation is clockwise
as viewed from the front of the unit.
If pump is turning in a counter
clockwise direction, this indicates the
pump wires are reversed.
Check the pump tubing for ruptures ,
wear, etc. Replace as needed
following the instructions printed in
this

Water pressure must be 20 psi
flowing or above.
Disassemble and check flow control
