Condition
Invalid washer size jumper (harness) configuration.
COMM
ERROR2
Wrong Washer
Size Jumper
Configuration
Delay
Immediate (after the wrong size jumper configuration
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 washer.
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.

Check VFD fault light before turning off power. Check
to ensure all the harnesses are properly connected to
the controller. Check to ensure the VFD drive
horsepower is proper for this size of washer. The

controller during startup (soft reset). Check orange
wires at Molex connector on controller coming from
pressure switch.
COMM
ERROR4
VFD Non
Existent or
communication
fault
Condition
This error is when the washer controller cannot
communicate with the drive.
Delay
Delay time is 2 seconds
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 the data communication cable between the
washer computer and the variable frequency drive
(VFD).
Step 1
: Make sure the cable did not become
unplugged during operation.
Step 2
: Make sure that the cable is not being pulled
sideways at either the washer controller, or the VFD,
plug end. If both ends of the communications cable
are plugged in the washer computer and VFD and
there is no tension on the communications cable
pulling it from side to side, then replace the cable.
Step 3
: Inspect both female connection points at PCB
controller and at VFD. These may need replacement if
they cannot be reset.
