Tub Full Of Suds; Wet Clothes; Will Not Lock/Unlock/Not Drain; Wrong Water Temperature - Amana NFW7200TW Technical Information

Troubleshooting
To avoid risk of electrical shock, personal injury or death; disconnect power to washer before servicing, unless
testing requires power.

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.
• 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.
• Check to see if belt is off motor and pulley.
• 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 (CN10). (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 drum. 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.
WARNING
• 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.
And then 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.
• 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.
