5. No Supply 2 Fill Analysis
No Supply 2 Fill Analysis
With the water turned on to
the machine, during a cycle
that has been programmed
for a supply 2 fill, no water is
filling compartment 2 of the
supply dispenser.
If the
output board includes a fuse at
the S2 location, test the S2 fuse with
an OHM meter.
If the output board does not include a
fuse at the S2 location, test the F20
and F21 fuses with an OHM meter.
Are any of the fuses blown?
Replace the blown fuse(s).
Remove the wires from solenoid V4
on the cold water valve, refer to the
No Supply 2 Fill Analysis
Dispenser Illustration. Start the
machine with a cycle that has been
programmed with a supply 2 fill.
Does the F20 and/or the F21 fuse
blow?
Inspect wire J22-1-8 V4.
Repair and/or replace the
wire as needed.
Reconnect the wires to
solenoid V4 on the cold water
valve. Does compartment 2 of
the supply dispenser fill with
cold water during a cycle that
has been programmed for a
supply 2 fill?
During a cycle
that has been programmed for a
supply 2 fill, during the cycle's fill step, is the
S2 light on?
If the output board includes a fuse at the S2
location, is there voltage (220 Volts AC)
between the S2 and the ACN?
If the output board does not include a fuse at
the S2 location, is there voltage (220 Volts AC)
between terminal J22-1-8
and the ACN?
Replace the output board.
Is there
voltage (220 Volts
AC) between solenoid V4 on
the cold water valve and the
ACN? Refer to the No
Supply 2 Fill Analysis
Dispenser Illustration.
Replace the cold water valve.
