Troubleshooting Procedures

!WARNING

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

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.

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.
