Tub Full of Suds
•
Check for restricted drain system. See Will Not
Drain and Will Not Spin.
•
Check for loose wire connections at control board
and pump.
•
Check to see if belt is off motor and pulley.
•
Use high efficiency or low sudsing detergent
specially formulated for front load washers.
•
Reduce detergent amount for that specific load
size and soil level. Towel loads have a minimal
amount of soil present and typically create more
suds.
•
Use drain pump and cold water to empty tub. See
Board Output Test .
•
Run the clothes washer through another com-
plete cycle using the coldest water, tablespoon
of salt and no detergent.
Wet Clothes
•
Very small clothes loads can cause unbalanced
loads. Add additional towels.
•
Excessive suds may have been present, due to
not using high efficiency detergent. Reduce
amount of detergent usage.
•
See Will Not Spin .
•
“Drain Only” or “Low” Spin Speed was selected.
Will Not Lock
•
Door not all the way closed or not properly
aligned. Possible laundry load is too large to
close door.
•
Place washer into Service Mode and check for
diagnostic codes 4,18 & 22. See Service Mode .
•
Check door lock system. See Board Output
Test . Check the output voltage of door lock coil. If
normal, change door lock switch. If not normal,
change main control board. (See “Component
Testing Information”).
•
Check electrical connections at door lock switch
assembly and machine control board (CN10),
(See “Component Testing Information”).
Will Not Unlock
•
Push door closed to make sure nothing from
inside is pressing against it, which may keep it
from unlocking.
•
Door locked from water level too high. Opening
door will result in water draining from door open-
ing.
•
Check for water remaining in the drum. If water is
present inside drum, see
Will Not Drain .
•
Check if temperature inside the drum is higher
than 50°C/122°F. If there is no problem with
temperature, check wiring of machine control
board and door lock switch.
•
Drain manually by removing drain hose clamp.
•
Display shows “ L0 ”. Press Power Off button to
turn off the washer and unplug and reconnect
washer. Press any key to turn on the washer. If
“
L0 ” is displayed, machine control board and door
lock switch should be checked.
•
Place washer into Service Mode and check for
diagnostic codes 4,18 & 22 . See Service Mode .
•
Check electrical connections at door lock switch
assembly and machine control board (CN10).
(See “Component Testing Information”).
•
Check door lock system. See Board Output
Test . Check the output voltage of door lock coil. If
120 V present, change door lock switch. If 120 V
not present, change machine control board. (See
“Component Testing Information”).
Will Not Drain
•
Check for restricted drain system.
•
In cold climates check for frozen drain hose.
•
Check for 120 V at the pump when a spin cycle is
selected.
•
Check pump motor winding resistance (See
“Component Testing Information”).
Normal resistance is about 14.2 ohms (±7%) .
•
Check that the machine control correctly senses
the water level in the washer. See
Board Input
Test .
•
Check drain pump. See Board Output Test.
•
Check the machine control board connections at
CN10 (Pin 6) for the pump. Should see 120 V.
(See “Component Testing Information”).
•
Check tub to pump hose for twist in hose.
Wrong Water Temperature
•
Check that both faucets are turned on fully.
•
Make sure water heater is set to deliver a
minimum of 120°F (49°C) hot water at the tap.
Also check water heater capacity and recovery
rate.
•
If the water heater is located a long distance from
washer, the water line may need to be purged
prior to starting wash cycle.
•
Too Hot/Too Cold: This washer uses a reduced
amount of water, while the control board meters
the incoming flow to regulate the actual tempera-
ture of the water in the tub. This may appear to be
significantly
warmer/cooler than expected.
•
Make sure the temperature selection is correct.
•
Disconnect inlet hoses from the Water Valve and
clean the valve screens of any debris.
