Fault Description Customer Action
COMM
ERROR 7
Communication
Bus Error
Condition If a state-of-health message reply is not seen by the
master microprocessor from the UC3 microprocessor
after 10 minutes, the master will reset the UC3 and
restart the 10 minute timer. Again, after 10 minutes,
if a state-of-health message is not received by the
master, it will reset the UC3 a second time. After 10
minutes, the master will reset the UC3 a nal time
and post a COMM ERROR 7.
Note: When the master resets the UC3, the control
will disconnect from the network. If the rst reset
is not successful, the control will not be able to
reconnect to the network, USB or card reader
functions.
Delay 3 cycles of 10 minutes (see above)
Action Stop the machine and clear the cycle. Keep the
door locked until the machine has stopped moving
and then unlock the door.
Solution The washer will not restart until the power is
removed and re-applied.
PCB
ERROR1
Controller Internal
Fault
Condition This error is an internal failure of the washer
controller electronics.
Delay Immediate
Action Stop the machine and clear the cycle. Keep the door
locked until the machine has stopped moving and
then unlock the door.
Solution Check VFD fault light before turning off power. Try a
soft Reset of the controller with the white button. If
problem. Replace PCB controller.
PCB
ERROR 2
Controller Internal
Fault
Condition This error is an internal failure of the washer
controller related to inputs being matched between
the master and slave micros
Delay Immediate
Action Stop the machine and clear the cycle. Keep the door
locked until the machine has stopped moving and
then unlock the door.
Solution The washer will not restart until the power is
removed and re-applied.

SLOW
DRAIN
ERROR
Drain Error Condition This error is when an empty water level is not
reach within 7 minutes.
Delay Immediate
Action The washer cycle will continue. Do not spin
the tumbler with out reaching an empty water
level. If empty water level is not reached,
agitate during the normal spin time.
Solution Check VFD fault light before turning off power.
Check to ensure the drain valve is operating
properly (slow drain has potential to cause this
code). Check to ensure the pressure switch
tube is clear of any blockage, and the pressure
switch is operating properly. Check the
pressure switch harness.
SPIN
STOP
ERROR
Stop Error Condition This error is when the washer does not stop
spinning within 150 seconds after receiving the
command.
Delay Immediate
Action Keep the door locked until the machine has
stopped moving and then unlock the door.
Solution Check VFD fault light before turning off power.
Inspect the braking resistors and measure
the resistance. Check connecting wiring from
braking resistor to the drive mounted in the top
of the washer. Reset the drive and try again.
Possibly incorrectly programmed drive.
DRIVE
ERROR
1
Washer size/ VFD
size mismatch
Condition This error is when the drive size does not
match the washer size.
Delay Immediate. (after the size jumper conguration
is read). Washer size/type inputs are read
only at power up, before starting a cycle, once
every 24 hours and in factory test mode
Action Stop the machine and clear the cycle. Keep
the door locked until the machine has stopped
moving and then unlock the door
Solution Check VFD fault light before turning off power.
If the controller was installed in a different
size machine before being installed in this
machine, a problem can occur. If someone has
been doing repairs on the washer, check for
the correct size drive. It can also be caused by
pressure switch harness. Check to ensure the
correct harness in installed. The control can be
reset by holding program button on controller
during startup (soft reset). Check orange wire
at Molex connector on controller coming from
pressure switch or replace pressure switch
harness.
