TROUBLE SHOOTING

WARNING

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

TROUBLE DIAGNOSIS

-As the micom wash machine is configured of the complicate structure, there might be the service call.

Below information is prepared for exact trouble diagnosis and suitable repair guide.

Caution for the Repair and Replacement

Please follow below instruction for the trouble diagnosis and parts replacement.

1)As some electronic components are damaged by the charged static electricity from the resin part of machine or the human body, prepare the human body earth or remove the potential difference of the human body and machine by contacting the power supply plug when the work contacting to PCB is executed.

2)Since AC120V is applied to the triac T1 and T2 on P.C.B, the electric shock may occur by touching and be careful that the strong and weak electricity are mixed.

3)As the P.C.B assembly is designed for no trouble, do not replace the P.C.B assembly by the wrong diagnosis and follow the procedure of the trouble diagnosis when the micom is not operated normally.

TROUBLE SHOOTING

WARNING

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

TROUBLE DIAGNOSIS

Will Not Start

•Plug the unit into the wall outlet. Check for proper voltage.

•Check fuse or reset circuit breaker.

•Push any key to turn on the washer and press the Start/Pause key to run the washer.

•Close door and push the Start/Pause key to run the washer.

•Check if washer is in a pause, soak or suds process. Wait briefly and it may start. (If the washer is in suds period, Suds will light up instead of remaining time.)

•Check for restricted drain system. (If there is electrical problem in drain system, “nd” error will occur after 15 minutes.)

•Check Water Supply.

•Check the line or water valve screen filter.

•Check if PCB connectors are assembled properly.

•Check if CN2 terminals on PCB are in good condition. (Refer to PCB Connector Check.)

•Replace PCB.

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 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. CN5 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

•Make sure to close the door completely.

•Check for water left inside the washer. If so, go to “Will Not Drain”.

•Perform Quick Test Mode or Quick Spin Test. Does the washer spin? (Before the test, empty the unit inside.) If it doesn’t tumble after the above, change PCB. When the problem persists, change the motor.

•Perform Quick Test Mode or Quick Spin Test. Does the washer spin? If it does, Check Possible unbalanced load scenario in normal mode.

•Check for loose connections at PCB, Water Level Sensor, Motor, Hall Sensor Wire Harness. (CN7,CN5,CN6) (Refer to the Component Testing Procedure.)

•Check motor windings resistance. (CN5 Pin1&3 = 11.6 ohms (at ±7% 20°C/68°F), Pin1&2 = 11.6ohms (at ±7% 20°C),

Pin2&3 = 11.6 ohms (at ±7% 20°C))
