Troubleshooting

4. No Cold Supply 1 Fill Analysis

No Cold Supply 1 Fill Analysis

With the water turned on to

the machine, during a cycle

that has been programmed

for a cold fill, no cold water

is filling compartment 1 of

the supply dispenser.

If the

output board includes a fuse at

the CF location, test the CF fuse with

an OHM meter.

If the output board does not include a

fuse at the CF location, test the F20

and F21 fuses with an OHM meter.

Are any of the fuses blown?

YES

Replace the blown fuse(s).

Remove the wires from solenoid V10

on the cold water valve, refer to the

No Cold Supply 1 Fill Analysis

Dispenser Illustration. Start the

machine with a cycle that has been

programmed with a cold fill. Does the

F20 and/or the F21

fuse blow?

YES

Inspect wire J22-1-12 V2.

Repair and/or replace the

wire as needed.

Reconnect the wires to

solenoid V10 on the cold water

valve. Does compartment 1 of

the supply dispenser fill with

cold water during a cycle that

has been programmed for

a cold fill?

During a

cycle that has been programmed for a

cold fill, during the cycle's fill step, is the CF

light on?

If the output board includes a fuse at the CF

location, is there voltage (220 Volts AC)

between the CF and the ACN?

If the output board does not include a fuse at

the CF location, is there voltage (220 Volts AC)

between terminal J22-1-12

and the ACN?

YES

Replace the output board.

Is there

voltage (220 Volts

AC) between solenoid V10 on

the cold water valve and the

ACN? Refer to the No Cold

Supply 1 Fill Analysis

Dispenser Illustration.

YES

Replace the cold water valve.
