Troubleshooting
The drive size setting has changed.
The variable frequency drive (VFD)
and the washer computer are not
communicating.
Washer controller internal error
Over-current on the drive or motor.
Check VFD fault code before turning off power. Check
to ensure all the harnesses are properly connected to
the controller. Check to ensure the drive horsepower is
proper for this size of washer. If no one has worked on
machine very recently then PCB controller or VFD may
need to be replaced. Do a soft reset before and after
either VFD replaced.
Check VFD fault code before turning off power. Turn
off the power to the washer. Wait one to two minute.
Turn on the power to the washer. If problem reappears,
contact your Dexter Authorized Representative.
Step 1: Check to make sure the washer cylinder turns
freely by hand. If it turns freely, continue to step 2. If it
does not, remove the belt and see if the motor turns
freely by hand. If the motor turns freely, then check for
obstructions in the cylinder or check the bearings. If the
motor does not turn freely, replace the motor.
Step 2: Check the motor wires for a short circuit
between leads. If there are motor leads that have
conductors touching, separate them and insulate them.
If the wires are broken, splice them together or replace
the motor.
Step 3: Check braking resistors to see if they measure
the correct resistance. If a resistor does not measure
the proper value, replace it.
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.
