Long Fill
LF flashes when the water level does not
change for a period of time OR water is
present but control does not detect the water
level changing.
Is water supply connected and turned on?
Are hose screens plugged?
Is water siphoning out of the drain hose?
Check for proper drain hose installation.
Is the pressure hose connection from the tub
to the machine/motor control pinched,
kinked, plugged, or leaking air?
See TEST #2, page 4.
Long Drain
Ld flashes when the water level does not
change after the drain pump is on.
Is the drain hose or the drain pump clogged?
Is the drain hose height greater than 96"?
Is the pressure hose connection from the tub
to the machine/motor control pinched,
kinked, plugged, or leaking air?
Is the pump running? If not, see TEST #7,
page 6.
Unbalanced Load
uL is displayed when the machine/motor
control detects an off-balance load, and is
steady on while the washer runs a mini-cycle
to rebalance the load. Display clears if mini-
cycle successfully rebalanced the load. If
(none)
the mini-cycle is unsuccessful, uL will flash
until the lid is opened.
Redistribute the load.
Verify that the washer is placed on a
level surface.
Overloaded
oL flashes when the machine/motor control
detects a load size that exceeds the
washer's capacity OR basket cannot
disengage. This may signify:
Load size exceeds washer capacity. Remove
excess laundry, then restart cycle.
Mechanical friction on drive mechanism,
not allowing the basket to disengage
(basket floating necessary to start agitation).

Suds Detection
Sd is displayed when the machine/motor
control, by analyzing drag on the basket,
detects a suds-lock condition, and is steady on
while the control then runs a mini cleanout
cycle. If the cleanout cycle is unable to correct
the over-sudsing problem, the cycle ends and
Sd flashes in the display. This may signify:
Load is bunched.
Excessive detergent usage.
Mechanical friction on drive mechanism,
not allowing motor to spin properly.
Open/Close Lid
lid flashes when one of the following conditions
occur:
User presses START/PAUSE with lid open.
User presses START/PAUSE after 2 consecutive
washer cycles without opening lid.
The machine/motor control cannot detect the
lid switch opening and closing properly.
See TEST #8, page 6.
Pump Out (lid opened)
Po flashes when drain pump begins pumping
out water from tub upon activation by the lid
(none) having been left open for more than 10 minutes.
Close lid to stop drain pump.
Hot, Cold Reversed
HC flashes when the hot and cold inlet hoses
are reversed.
Make sure inlet hoses are connected
(none)
correctly.
If hoses are installed properly, Automatic
Temperature Control may be stuck in low
resistance range. See Test #5, page 5.
Lid Lock Failure
dL flashes if the following conditions occur:
Lid is not closed completely due to
interference.
Check for lock interference with lid or lock
bezel.
Wash media buildup is preventing the lock
bolt from extending.
Machine/motor control detects open lid
switch when attempting to lock.
Machine/motor control cannot determine
if lid lock is in a locked state.
See TEST #8, page 6.
Lid Unlock Failure
dU flashes if the following conditions occur:
Excessive force on lid is preventing lock bolt
from retracting.
Wash media buildup is preventing lock bolt
from retracting.
Machine/motor control cannot determine if
lid lock is in an unlocked state.
See TEST #8, page 6.

Pressure Signal Out-of-Range
F then 1 flashes when the control detects an
out of range pressure signal.
Check pressure hose connection from tub
to machine/motor control. Is hose pinched,
kinked, plugged, or leaking air?
If F then 1 repeats numerous times after
POWER/CANCEL is pressed and the
pressure hose connection is not pinched
or kinked, replace the machine/motor control.
Keypad/User Interface Failure
F then 2 flashes when in:
Diagnostic Test mode if a stuck key is detected.
Standby mode if there is an internal problem
with the user interface.
See TEST #4, page 5.
Communication Error
36
Communication between the CCU and the
User Interface has failed.

See TEST #10, page 6.
ATC Thermistor Open/Short
F then 40 flashes when the ATC Thermistor is
detected to be open or shorted.
See TEST #5, page 5.
Motor RPS Thermistor Open/Short
F then 41flashes when the motor rotor position sensor
(RPS) thermistor is detected to be open or shorted.
See TEST #3, page 4.
NOTE: This error code is only displayed when
viewing saved fault codes.
See Diagnostic Test, page 1, for accessing
saved fault codes.
Heater in unknown state
F then 42 flashes when the control cannot
detect if the heater is ON or OFF.
See TEST #9, page 6.
Heater is continuously ON
F then 43 flashes when the heater is ON when
it should be OFF.
See TEST #9, page 6.
Heater cannot be turned ON
F then 44 flashes when the heater has been
turned ON by the control, but the control
cannot detect that the heater is ON.
See TEST #9, page 6.
Motor Stalled
F then 50 flashes when the motor rotor
position sensor (RPS) senses no rotation.
Does basket turn freely? If not, make sure
bottom shipping pack has been removed.
Determine cause of friction.
If basket turns freely, see TEST #3, page 4.
Motor RPS Failure
F then 51 flashes when there is a motor rotor position
sensor (RPS) failure or lower harness problem.
See TEST #3, page 4.
Motor Stop Failure
F then 52 flashes when the motor rotor position
sensor (RPS) senses rotation after Stop command.
See TEST #3, page 4.
