Troubleshooting Procedures

!WARNING

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

Place washer into Service Mode and check for diagnostic codes. See Technical Data Sheet taped to rear panel.

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

Check dispenser hose to outer tub for obstructions or restrictions.

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

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 incoming 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%,

Pins 1 & 2 = 11.6ohms ±7%,

Pins 2 & 3 = 11.6 ohms ±7%

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%, Pins 1 & 2=11.6ohms ±7%, Pins 2 & 3=11.6ohms. ±7%.

No Water Fill

Test water fill. Perform Board Output Test.

Check to make sure water supply is turned on fully.

Check electrical circuit and connections at the Water Valve, and Pressure Switch.

Check for kinks in inlet hoses.

Check for clogged inlet screens.

Visually check hot, cold, bleach and softener water valves separately for fill.

Check for low water pressure. May be dependent on pressure entering home. Variations may occur due to usage in the home at the time machine is used.

Check for frozen pipes and hoses.

Check resistance of Water Valve coils. (Normal 1.18Kohms; Check resistance of water valve coils. Check Pin #1 of CN5 and Pin # 1,2,3,4 of CN10.

Check for loose connections at the Pressure Switch or on the Machine Control Board, CN3. (Refer to the component Testing procedure).

Tub Full of Suds

Check for restricted drain system. See Will Not Drain and Will Not Spin.

Check for loose wire connections at Control
