Samsung WF328AAG/XAA - WF328AAR/XAA - WF328AAW/XAA 

Quick Test Mode
Note: This test erases all faults and memory:
To enter press Spin, Silver Care, & Power simultaneously with the power off.
1. All LED’s light up and the washer beeps as it enters the Quick Test Mode.
2. The unit displays the software version for a second then clears the EEprom.
3. After the displaying the software version, LCD will display Model information. If EEEE is displayed the PCB ass’y is defective.
4. When the version is displayed. Press the following keys to test the various components
Press Temp Key to cycle through the Water Valves in this order: Pre Cold, Cold Main, Bleach, Cold Main & Bleach for Fabric Softener, Hot, then off.
Press Spin Key to test Motor circuit.
Press Soil Key to test Drain Pump
Service Mode:
This mode allows more detailed operation tests and troubleshooting, to enter
Press Signal & Extra Rinse simultaneously with the power on.
While in Service Mode the following tests can be performed:
Quick Spin Test = Delay Start & Silver Care:
This accelerates the drum motor from 0 to maximum RPM over a few minutes.
Note: Stay with the washer during this test, out of balance detection may be bypassed.
Press the Start/Pause button during the test to hold its spinning speed for 10 minutes before going back to Quick Spin Test Mode.
Cycle Count = Press the Signal button to see how many times the unit was used
Soft Ware # = Press the Soil button to see the software version. Fast Time Down = Press the Temp button to advance to the next cycle
Fault Code Test = Press the Silver Care button to view the stored fault codes – then turn Dial to view error codes (Push Start/Pause while the code is displayed to view the number of cycles since the error occurred)
Peripheral (Main PCB) input Tests
1. Extra Wash. Then turn the Dial so that the Normal LED is turned on. Next, press the Start/Pause Key. The Water Temperature will be displayed in Fahrenheit.
2. Extra Wash. Then turn the Dial so that the Whites LED is turned on. Next, press the Start/Pause Key. The door status will be displayed (OP if open, CL if closed).
3. Extra Wash. Then turn the Dial so that the Perm Press LED is turned on. Next, press the Start/Pause Key. The door lock Switch status will be displayed (UL if unlocked, Lo if locked).
4. Extra Wash. Then turn the Dial so that the Quick Wash LED is turned on. Next, press the Start/Pause Key. The Water Frequency will be displayed.
5. Extra Wash. Then turn the Dial so that the Sanitize LED is turned on. Next, press the Start/Pause Key it will display the Ag Kit Status in 3 seconds: “- -” if AG kit is operated properly. “7E” if AG kit is out of order (check wire harness & PCB)
EEPROM Clear Check
Power off, Press Delay Start, Signal and Power Key at the same time. Good = Good Fail = FAiL. All memory will be cleared, including Fault Codes. This should be done when a new
Main PCB is installed
Component location on main board 
Error codes causes and solution
LE 8
Water Level Sensor
Check the Hose where the sensor is connected, may be loose, pinched, damaged or clogged. Also check the sensor it may be disconnected or defective. The Main PCB may also be defective.
3E, bE ,25, E3
Motor Drive Error or Hall Sensor error
Check the motor drive connector, it may be loose. The hall sensor may be disconnected, loose or damaged . Check for a foreign object inside the motor or motor damage. The stator might be loose or damaged. The drum might be overloaded from too many clothes or the relay or PCB might be defective.
Water Supply Error
Check the water valve wiring harness.
Check whether the water supply valve is clogged with foreign material and whether water is supplied properly.
Check for reversed fill hoses
Check water temperature, if sensed as higher than 50 ˚C in the
Wool or Lingerie cycle it will create error.
Check the relays, if they operate correctly replace the Main PCB.
Fill Hoses Reversed
System Error
Correct Hot/Cold hose connections
Replace PCB
Drain Error
Check for Foreign material entering the pump or hoses.
Check to make sure the wiring harness is connected properly.
Check the water pump terminal .
Check for freezing
Power Error
Make sure to check the operating voltage. (An error occurs when under or over voltage is supplied.) Check whether a plug receptacle is used. When the connecting wires are too small (extension cord use), a momentary low voltage may drop up to 10 V
Main PBA fault (sometimes)
Momentary Power Failure
Communication Error
Check the wire connections and terminal contacts between the sub and main PBAs.
Check for disconnected wires.
Check whether the sub PCB is short circuited because of moisture.
If the main PCB’s communication circuit is faulty, replace it.
Go to “EEPROM Clear Mode” If display shows “FAiL”, Replace Machine Control Board.
E2,15, SR
Switch Error (Main Relay Error)
Check whether either the Power switch or a tact switch (any button) is stuck down.
Check whether the service PBA holding screws are fastened too tight pinching the contacts
If the main PBA switching IC on/off error has occurred, replace the main PBA.
The “E2” error occurs if the main relay connections are incorrect.
Check the connections. If there is no error in the connections, replace the main PBA
dS22 (Before operation), dL18 (During operation), LO2 (Unlock Fail) ,FL 4 (Lock Fail)
Door Error
Check the door switch and latch alignment .
Check the latch for damage
Check the wiring harness to the latch.
Check the door switch. Replace if faulty.
Check the main PBA door sensing circuit. Replace if faulty.
Finally verify he operation of the Main PCB
Hr 36 (Heater Relay)
Heater Error
This can be a short or a wire disconnected to the heater circuit. This can also be problem with the tub contacting the heater or if the water in the tub is frozen or there is no water. The error is triggered by temperatures above 145C. If the heater has no error, this occurs because of a PBA relay malfunction. Check the wiring harness to the heater.
An Hr error occurs if the steam heater, is faulty, replace it.
9E1, OE, E
Overflow error
EMC Filter issue or a noise spike from an external device
Water is supplied continually because the water level detection does not work. - Verify the drain is working properly, the water level detection does not work and water is supplied continually. Verify the water valves shut off fully. Finally check the water level sensor.
dC 10
Unbalance Error
Check the type of laundry. Check whether it may cause an unbalanced situation.- Educate the consumer in this case, to press pause, reposition the load or remove a few items. Press start to continue and complete the wash cycle.
SUdS, Sd
Foaming Detected
This occurs when too much foaming is detected. It is also displayed while foaming is removed. When the removal is finished, the normal cycle proceeds. (This is one of the normal operations. It is an error for preventing non-sensing faults.)
