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
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 .
• “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 Procedures”).
• Check electrical connections at door lock switch
assembly and machine control board (CN10),
(See “Component Testing Procedures”).
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 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 Procedures”).
• 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 Proceduress”).
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 Proceduress”).
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 Procedures”).
• 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.
• Disconnect inlet hoses from the Water Valve
and clean the valve screens of any debris.
