Troubleshooting Guide

L2005-005

Slide 1 – Troubleshooting Slide 2

Always refer to the Technical Data Sheet shipped with the product for detailed information

for the model you are servicing. Follow all Caution and Safety Warnings

The following is an example of the information available on the Technical Data Sheet

Will Not Start

• Plug cord into live electrical outlet. Check for proper voltage.

• Check fuse or reset circuit breaker.

• Push any key to turn on the clothes washer. Push the rotary selector knob to start the washer.

• Close door and push the rotary selector knob to start the clothes washer.

• Check to see if the washer is in a pause or soak period in the cycle. Wait briefly for machine

to start. (If washer is in suds period, “SUDs” will display instead of remaining time.

• Check for restricted drain system. During an electrical drain problem, “nd” error will occur after 15 minutes.

• Check water supply is working.

• Check water valve connections are good.

• Check the line filter and water valve filter.

• Check the machine control board terminal connections CN5, CN6 for good connections.

• Replace console control board.

Leaking

• Make sure inlet hose connections are not leaking. Check for rubber gasket damage due to over-tightening.

• Check standpipe for leak. Wrap a dry rag around the standpipe opening. If rag becomes wet, leak is fault of home plumbing. Be sure the standpipe is capable of accepting the flow of water from the washer.

• Make sure end of drain hose is correctly inserted and secured to drain standpipe.

• Check internal hose connections (fill, drain systems, dispenser hoses & clamps).

• Check rubber boot. Remove, reposition and reinstall, if necessary.

• Check for possible kinked dispenser to outer tub hose. Hot water pressurization may force

door open.

No Tumble

• Start normal cycle with an empty machine and allow a fill to check tumble.

• Perform Board Output Test, or Quick Spin Test (Before test, make sure that the tumbler is

empty.)

• Check for loose connections at Machine Control Board, Pressure Switch, Motor, Tach Harness and Motor Control. (Refer to the component testing procedure)

• Check motor windings resistance. (CN9 pins 1 &3 = 11.6ohms(±7% 20°C/68°F basis), pins 1 & 2 = 11.6ohms(±7%20°C/68°F basis), Pin2 & 3 = 11.6 ohms (±7% 20°C/68°Fbasis)

• Check belt.

• Faulty Main Control Board.

• Faulty motor.

Will Not Spin

• Check to make sure the door is fully closed.

• Check for water left inside the washer. If present, see Will Not Drain.

• Perform Board Output Test or Quick Spin Test. (Before test, make sure that the tumbler is

empty.) If it doesn’t tumble after the test above, check unbalanced load scenario, Main Control Board, and motor.

• Check for loose connections at Machine Control Board, Pressure Switch, Motor, Tach Harness and Motor Control. (CN8, CN9, CN3) Refer to the component testing procedure.

• Check motor winding resistance (CN9 pins 1&3=11.6ohms ±7%@68F, pins 1&2=11.6ohms ±7%@68F, pins 2&3=11.6ohms. ±7%@68F.

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.

• 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 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.

• Disconnect inlet hoses from the Water Valve and clean the valve screens of any debris.

Noisy and/or Vibration/Walking

• Check if the washer was properly leveled and the locking nuts are securely tightened up against the base frame of the washer.

• Check and determine all four of the shipping bolts and spacers have been fully removed from the rear panel of the washer.

• Check for proper load size and distribution. If clothes load is too small, add a few towels to balance the clothes load better.

• Check the tightness of the rear pulley bolt. Tighten if necessary.

• Clean floor and bottom side of washer feet. Check clearance. Refer to the back of machine

and Installation Instruction.

Rubber Feet Leaving Marks on Floor

• Use a pencil eraser to remove mark.

• Walk washer into location, do not drag.

Additive Cups Full of Water

• Small amount of water in bottom of additive cups is normal.

• Remove and wash Dispenser Tray, removable Cup, and Rinse Cap.

• Level washer.

•

Buttons do not Respond

• Option and Function buttons respond differently according to each cycle.

• Child Lock feature has been selected. To disable feature press and hold Wash/Rinse Temp

and Spin Speed simultaneously until a beep is heard.

• When display shows "End", only the Power Off button will function. Press Power Off and

make new cycle selections.
