Board and pump.
• Perform Board Output Test.
• 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.
• Run the clothes washer through another
complete 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.
• Low Spin Speed or Drain Only 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.
• Perform Board Output Test. Check door
lock system. Check the output voltage of Door
Lock Coil. If normal, change door Lock
switch, If not normal, change Main Control
Board. (Refer to the Component Testing
procedure.)
• Check electrical connections at lock switch
assembly and machine control board (CN5
and CN9). (Refer to the Component Testing
procedure.).
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 opening.
• Check for water remaining in the tub. Check
the temperature inside the drum is higher
than 50°C/122°F. If water is present inside
drum, refer to “Will not drain”, If there is no
problem with temperature, check wiring of
Main Control Board and Door Lock Switch.
• Drain manually by removing drain hose
clamp.
• Display shows LO. Press power Off Key to
turn off the washer and unplug and reconnect
washer. Press any key to turn on the washer.
If LO is displayed, Main Control Board and
Door Lock Switch should be checked.
• Place washer into Service Mode and check
for diagnostic codes 4,18 & 22.
• Check electrical connections at lock switch
assembly and Machine Control Board (CN10).
(Refer to the component Testing procedure.)
• Perform Board Output Test. Check door
lock system for loose connections.
• Perform Board Output Test. Check door
lock system. Check the output voltage of Door
Lock Coil If 120V present change door Lock
switch, If not present, change Main Control
Board. (Refer to the component Testing
procedure.)
Will Not Drain
• Check for restricted drain system.
• In cold climates check for frozen drain hose.
• Check for 120 VAC at the pump when a spin
cycle is selected.
• Check pump motor winding resistance. (14.2
±7% ohms)
• Check that the machine control correctly
senses the water level in the washer. See
Board Input Test.
• Go to Board Output Test and perform Pump
Out Test.
• Check the Machine Control Board
connections at CN10 (Pin 6) for the pump.
Should see 110-120VAC.(Refer to the
component testing procedure).
• 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 temperature of the water in the tub.
This may appear to be significantly
warmer/cooler than expected.
• Make sure the temperature selection is
correct.
