The cycle begins with a wash fill. The water temperature is deter-
mined by the temperature selected on the control. While water
fills the washtub, a column of air is trapped in a pressure bulb and
hose. The air pressure continues to increase as the washtub fills

with water until the air pressure hose reaches a level determined
by the selected water level (load size switch setting) and the se-
lected cycle. The water will stop filling at the minimum level for
the selected cycle when Auto Fill is selected. In either case, the
washer will begin load sensing to determine if more water is re-
quired for the actual load in the washer and the cycle selected.
The wash agitation segment of the cycle begins at this time and
the lid must be closed and locked for any further washer opera-
tion. On non-Eco cycles, after approximately two minutes of
wash, the washer repeats the load sensing process to confirm that
the water level is still correct for the load and cycle selected.
The washer uses a reversing type of inverter drive motor and a
special stretch drive belt.
During agitation, the motor alternates between the clockwise and
counterclockwise direction. The rapid reversal from one direction
to the other creates the wash action. The stretch belt needs no ad-
justment for belt tension. Proper belt tension is provided by the
pulley spacing and use of the proper size stretch belt. This elimi-
nates belt slippage and ensures an efficient wash action.
After the wash agitation is complete and a short pause occurs, the
control advances into the wash spin. During spin, the washtub
will first rotate at 20 RPM while the electric pump runs to drain
the water from the tub. Once the pressure sensor recognizes that
the tub has been drained, the RPM will increase to extract water
from the load and the pump will continue running to remove the
water.
Water is introduced during the wash spin to spray the garments
and remove suds from them. The wash spin is followed by a rinse
step to rinse away any detergent residue.
During the rinse step in the Normal Eco cycle there will be two
more spray rinses. Water is sprayed into the washtub while it is
spinning. In all other cycles, the washer fills and then agitates
like the wash portion of the cycle.
Following the rinse step a final spin extracts the rinse water from
the clothes preparing them for the dryer. This will also start at 20
RPM with the pump running. After draining the spin will then in-
crease to a higher speed that varies depending on what cycle has
been selected. After the machine has been in spin long enough to
ensure that most of the water has been removed from the load,
the pump will run intermittently for the rest of the spin in order to
improve drain performance and reduce noise.
Refer to Cycle Sequence Charts section for a detailed breakdown
of each cycle.

SPIN LEDs are on and the machine enters a Delicate Cycle Short
agitate.
The control will remain in this step until the Start/Pause button is
pressed.
Factory Spin Test
This step checks the spin speeds. The machine steps through spin
speeds and maintains each speed for a few seconds. After 820
RPM, the motor will stop. All OBL checking is done and if either
the out of balance switch is hit or the OBL check fails at 300
RPM, the time will be reset indefinitely to allow the load to be
rebalanced so that it can spin up and reach full speed.
The control will advance to the next step if the Start/Pause button
is pressed at any time during this step.
During this step, if 300 RPM is reached, the WASH LED will be
lit. If 500 RPM is reached, the RINSE LED will be lit. If 820

Non-Fatal Unbalance Error, maximum in-
tended speed not reached in final spin
Machine has sensed load is unbalanced. Re-balance load and try
spin step again. Do not adjust balance switch first. Most likely
not due to unbalance switch mounting. If load is only one big
item, add towels on opposite side to balance load. May also be
due to excessive suds in load or too much water left in tub due to
slow draining.
WASH, SPIN 2
times
Fatal Unbalance Error (through Serial No.

Dipswitch/Voltage Configuration Error Unexpected supply voltage: Check the harness connections be-
tween the front end control and the drive board. If the front end
control was replaced, set dip switch 1 to the same setting as the
previous control. If reworking the machine to use a different
voltage supply, dip switch 1 setting may need to be changed. If
dip switch 1 setting is changed, power down, power up and try
again. Also check pin H2-7 on the front end control to ensure
good connection between front end control and drive board.
Drive Errors
All LEDs 6 times Voltage Select Error Wrong input voltage seen at drive board. (120 Volt or 240 Volt)
Dip switch 1 on front end control set wrong. There could possi-
bly be water on drive board (let drive dry out and determine
cause of water). Unpower to clear error. Replace drive board if
error persists.
All LEDs 1 time Over Voltage AC-Main Input Error Machine voltage is too high. Check supply voltage to the ma-
chine and verify that it is within machine specifications. Unpow-
er to clear error. Replace drive board if error persists.

ous
Power Fail Dangerous Error The neutral line power input to the machine was seen out of
range. Unpower to clear error. Check for damage in the power
supply harness. Replace power supply harness or drive board if
error persists.
All LEDs 5 times Over Voltage DC Bus Error Unpower to clear error. Check voltage input to machine. If it
happens only at start of spin, replace motor. Replace drive board
if error persists.
