General Troubleshooting
To reduce the risk of electric shock, fire, explosion, serious injury or death:
• Disconnect electric power to the washer before servicing.
• Never start the washer with any guards/panels removed.
• Whenever ground wires are removed during servicing, these ground wires must
be
re
connected to ensure that the washer is properly grounded.
• Motor not grounded! Disconnect electric power before servicing motor.

WARNING
5. Troubleshooting Knocking Noise
If a frontload washer produces a noise similar to a
kn
ock on a door, it might be due to a flat spot on
the belt. The knocking sound is made when
the
flat spo
t hits the pulley. The knocking may occu
r
during a ramp spin and fade after reaching a
higher RPM.
To correct this condition, replace the belt.
6. Explanation of LEDs on Drive
Control
There are four LEDs on the control to assist with
troubleshooting (refer to Figure 2):
1. Green LED on constant = 5VDC power supp
ly
pre
sent
2. Green LED flashing one second on/one second
off = drive control is active
3. Red LED flashing = drive contro
l is
co
mmunicating with front end control
4. Red LED on constant = DC Bus Charged
NOTE: Drive is only powered when door is closed
and front end control turns it on.
7. Door Fails to Unlock at End of
Cycle
If the door won’t unlock at the end of the cycle and the
cycle time is flashing in the display, the water might be
too hot to drain. Add a cool-down step to the cycle to
make sure the water will be cooled. Enable the cool-
down feature by setting the cool down dip switch (#6)
to ON.
8. No Spin
A no spin condition is not caused by intermittent
operation of the motor or motor control (inverter
assembly). DO NOT replace these components for no
spin complaints if the unit passes the following
procedure:
