Action
Stop the machine and clear the cycle.
Keep the door locked until the machine has
stopped moving and then unlock the door.
Solution
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.

Action
Stop the machine and clear the cycle.
Keep the door locked until the machine has
stopped moving and then unlock the door.
Solution
Step 1: Measure the supply voltage to the
VFD on the L1, L2 (or N), and L3 (if
connected to three phrase power). The
supply voltage should be from 187 to 264
VAC or 108 to 132 VAC for a 120 VAC VFD.
Also make sure the supply wires on L1, L2
(or N) and L3 (if connected to three phase
power) are securely connected.
Step 2: Check the braking resistor
connections at the VFD. The terminal
screws should be tight. One of the braking
resistor wires should be connected to
terminal B2.
Step 3: Measure each braking resistor
separately to make sure they are the
correct resistance. (200 for 1, 2 and 3 Hp
VFD and 160 for 5 Hp and larger VFD).
Step 4: If you have a 240 VAC, high leg
voltage supply, try disconnecting the high
leg. If this cures the problem, leave the
high leg disconnected, connect a transient
voltage surge suppressor (with some form
of filtering) at the voltage supply panel,
connect a line choke on the high leg or
install a VFD filter.
