ERROR CODES
Serial Communication Error
Communication between
the
Central
Control Unit
(CCU)
and the Motor Control Unit
(MCU)
cannot
be
sent
correctly.
PotentialCauses
.
Check Wire Harness connections
to the MCU. the
motor,
and
Central Control
Unit
(CCU)
.
Check the Drive system
lor
any
worn or
failed components
.
Replace MCU
.
Replace CCU
.
Replace Motor
.
Replace
Wire
Harness
Dispenser Circuit
Error
lf
the dispenser
motor is not able to be driven
to
it's
proper position.
PotentialCauses
.
Check
mechanical linkage f rom dispenser
motor to the top of the
dispenser.
.
Check
Wire Harness connections to
the dispenser
motor and
Central
Control
Unit
(CCU)
.
Replace Dispenser
Motor
EEPROM Error
The Central Control
Unit
(CCU)
receives
it's data
from
an
EEPROM on board the
CCU.
lf there is an error
readino
this data
it will cause
this
error.
PotentialCauses
.
A
power glitch
may cause this error.
Try
unplugging
the Unit
for
two
minutes to
see
if
that
fixes the error.
.
Replace
CCU.
Motor
Control
Unit
(MCU)
Error
lf
the MCU detects
multiple resets or errors
during a
wash
cycle
it will
go
into
this
error mode.
PotentialCauses
.
Check
Wire Harness connections
to the
MCU, the
motor,
and
Central Control
Unit
(CCU)
.
Check Drive belt
.
Reolace MCU
.
Reolace
Motor
.
Replace
Wire
Harness
SUDS LOCK
(Overdose
of Detergent detected
during
the Wash Cycle)
The motor
control
unit senses
a suds
lock condition by analyzing
the current draw
on
the drive
motor. lf
"Sud"
is displayed
a
potential
suds
lock is detected.
This may
signify a bad
pump,
an extra
heavy load,
excessive detergent,
or excessive suds.
