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.

operating properly. Check the pressure
switch harness.
