Quick Test Mode
Note: This test erases all faults and memory:
To enter press Spin, Soil, & Power
simultaneously with the power off.
1. All LED’s light up and the washer beeps as it
enters the Quick Test Mode.
2. The unit displays the software version.
3. After the displaying the software version, turn
Jog dial CCW Once, or Twice (showing zeros) on
some units
If EEEE is displayed the PCB ass’y is defective.
Press Temp Key (press spin to lock door if neces-
sary) to cycle through the Water Valves circuit test in
this order: Cold Main, Bleach, Cold Main & Bleach for
Fabric Softener, Hot, then off.
Press Soil Key to test the motor
Press Spin to test Door Lock/Unlock circuit.
Press Signal Key to test the Pump
Service Mode:
This mode allows more detailed operation tests and trouble-
shooting, to enter press Signal & Extra Rinse
simultaneously with the power on.
While in Service Mode the following tests can be performed:
Quick Spin Test = Delay Start & Spin: This accelerates
the drum motor from 0 to maximum RPM over a few min-
utes. Note: Stay with the washer during this test, out of bal-
ance detection is bypassed and the door may not lock.
Press the Start/Pause button during the test to hold its spinning
speed for 10 minutes before going back to Quick Spin Test
Mode.
Cycle Count = Press the Signal button to see how many times
the unit was used
Soft Ware # = Press the Soil button to see the software version
information
Fast Time Down = Press the Temp button to advance to the
next cycle
Fault Code Test = Press the Spin button to view the stored fault
codes – then turn Dial to view error codes (Push Start/Pause
while the code is displayed to view the number of cycles since
the error occurred)
Peripheral (Main PCB) input Tests
1. Select Extra Wash. Then turn the Dial so that the Heavy is
turned on. Next, press the Start/Pause Key. The Water
Temperature will be displayed in Fahrenheit.
2. Select Extra Wash. Then turn the Dial so that the White is
turned on. Next, press the Start/Pause Key. The door status will
be displayed (OP if open, CL if closed).
3. Select Extra Wash. Then turn the Dial so that the Perm.
Press is turned on. Next, press the Start/Pause Key. The door
lock Switch status will be displayed (UL if unlocked, Lo if
locked).
4. Select Extra Wash. Then turn the Dial so that the Wool is
turned on. Next, press the Start/Pause Key. The Water
Frequency will be displayed.
IMPORTANT SAFETY NOTICE – “For Technicians Only” This service data sheet is
intended for use by persons having electrical, electronic, and mechanical experience
and knowledge at a level generally considered acceptable in the appliance repair trade.
Any attempt to repair a major appliance may result in personal injury and property
damage. The manufacturer or seller cannot be responsible, nor assume any liability for
injury or damage of any kind arising from the use of this data sheet.
Location considerations
Do not install your washer in areas where
water may freeze, since your washer will
always maintain some water in its water valve,
pump, and hose areas. This can cause
damage the belts, the pump, hoses and other
components. Operating temperature should
be above 60°F/16°C.
EEPROM Clear Check
Power off, Press Delay Start, Signal and Power Key at
the same time. Good = Good Fail = FAiL
All memory will be cleared, including Fault Codes
This should be done when a new Main PCB is
installed
Please Note: There are
two Versions of this model,
verify you are ordering the
correct parts for the Version
you are servicing.

Check the motor drive connector, it may be loose. The hall sensor
may be disconnected, loose or damaged . Check for a foreign ob-
ject inside the motor or motor damage. The stator might be loose
or damaged. The drum might be overloaded from too many
clothes or the relay or PCB might be defective.

Make sure to check the operating voltage. (An error occurs when
under or over voltage is supplied.) Check whether a plug recepta-
cle is used. When the connecting wires are too small (extension
cord use), a momentary low voltage may drop up to 10 V

tight pinching the contacts
If the main PBA switching IC on/off error has occurred, replace the
main PBA.
The “E2” error occurs if the main relay connections are incorrect.
Check the connections. If there is no error in the connections, re-
place the main PBA

(Heater
Relay)
This can be a short or a wire disconnected to the heater circuit. This
can also be problem with the tub contacting the heater or if the wa-
ter in the tub is frozen or there is no water. The error is triggered by
temperatures above 145C. If the heater has no error, this occurs
because of a PBA relay malfunction. Check the wiring harness to
the heater.
An Hr error occurs if the steam heater, is faulty, replace it.

Water is supplied continually because the water level detection
does not work. - Verify the drain is working properly, the water level
detection does not work and water is supplied continually. Verify the
water valves shut off fully. Finally check the water level sensor.
Temperature
Sensor Error
29 The washing heater temperature sensor in the tub has an error.
Check the connections for the washing heater temperature sensor
connector.
Unbalance

Check the type of laundry. Check whether it may cause an unbal-
anced situation.- Educate the consumer in this case, to press
pause, reposition the load or remove a few items. Press start to
continue and complete the wash cycle.
Foaming
Detected
SUdS
Sd
This occurs when too much foaming is detected. It is also displayed
while foaming is removed. When the removal is finished, the normal
cycle proceeds. (This is one of the normal operations. It is an error
for preventing non-sensing faults.)
Check whether the washing machine is level to the floor with respect to the original position of the washing machine prior
to service. Doing this now will reduce the need for a redo call and customer dissatisfaction.
✔ Vibrations can shorten the lifetime of the product.

When using non-HE
detergents, or using
too much detergent
for the water hard-
ness and soil level of
the clothing, over
sudsing will occur.
When this happens
there will be leaks out
of the detergent
drawer and door.
Please advise con-
sumer of proper de-
tergent usage.

It is normal for some water to remain in
Detergent Drawer after it completes
washing. Bleach is usually flushed out
into the tub at the beginning of the wash-
ing. Also, its compartment is washed
again during the following rinse cycle,
removing any remnants.
