Maintenance Features

Error Type and Mode Details:

The document provides a comprehensive list of error codes (LED and LCD) along with their descriptions and troubleshooting steps.

LE8 (Water Level Sensor Problem): Check for any leakage on the base, hose, valve, and tub connections. If the problem persists, replace the main PCB. If the washer is undergoing natural draining, this error occurs because the drain bellows are clogged with foreign material. Remove the foreign material.
3E, E3, bE25 (Motor Drive Error or Hall Sensor error): Check the motor drive connector. If it's loose or damaged, check the motor or motor damage. The motor might be overloaded from too many clothes, or the relay or PCB might be defective.
nF3 (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 higher than 50 °C in the Wool or Lingerie cycle, it will create an error. Check the relays; if they operate correctly, replace the Main PCB.
nF1 (Fill Hoses Reversed): Correct hot/cold hose connections.
SF1, SF2, SF3 (System Error): Replace PCB.
nD1 (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.
2E, 91, 92 (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 used), a momentary low voltage may drop up to 10 V. Main PBA fault (sometimes).
PF (Momentary Power Failure):
AE (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.
11 (EEPROM Fault): Go to "EEPROM Clear Mode." If the display shows "FAIL," replace the Main Control Board.
E2, 15 (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 (Door is open):
dL18 (Door Error - during operation): 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 the operation of the Main PCB.
LO2 (Unlock Fail):
FL4 (Lock Fail):
Hr36 (Heater Error): This can be a short or a wire disconnected to the heater circuit. This can also be a problem with the tub contacting the heater or if the washer 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 (EMC Filter issue or a noise spike from an external device):
OE, E (Overflow error): 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.
29 (Temperature Sensor error): The washing heater temperature sensor in the tub has an error. Check the connections for the washing heater temperature sensor connector.
dC10 (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.
7E (Silver Care Kit PCB Failure): Check Silver Care PCB, Main PCB & Wire-harness.
8E (Mems or Harness Failure): Check MEMS PCB, Main PCB & Wire-harness.
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.)

General Maintenance:

Checking Washer Level: Check whether the washing machine is level to the floor with respect to the original position of the washing machine prior to service. Doing this now will reduce the need for a redo call and customer dissatisfaction.
Vibrations: Vibrations can shorten the lifetime of the product.
Foot Pad for Walking Washer: There is one in each package, so order 4. When installing a washer and dryer on the first or second floor, do not exceed this leg adjustment height for stability.
Detergent Drawer Maintenance: It is normal for a small amount of water to remain in the Detergent Drawer after it completes washing. Bleach is usually flushed out of the tub at the beginning of the washing. Also, its compartment is washed again during the following rinse cycle, removing any remnants.
Laundry Touch Up Paints: Available in various colors (Blue Onyx, Imperial Silver, Near White, Stratus Gray, Tango Red) with corresponding part numbers (DH81-11980A, DH81-11981A, DH81-11982A, DH81-11983A, DH81-11984A).
Stacking Kit: (Model No: SK-3A1/XAA, SK-4A/XAA, SK-5A/XAA) Samsung washers and dryers can be stacked to maximize usable space. An optional stacking kit is available for purchase from your Samsung retailer.
Detergent Usage: When using non-HE detergents, or using too much detergent for the water hardness and soil level of the clothing, over sudsing will occur. When this happens, there will be leaks out of the detergent drawer and door. Please advise consumer of proper detergent usage.
Location Considerations: Do not install your washer in areas where water may freeze, since your washer will always maintain some water in its water valve, pump, and hose areas. This can cause damage the belts, the pump, hoses and other components. Operating temperature should be above 60°F/16°C.
Sanitize and Pure Cycle Wash Cycles: The unit sometimes will pause during Sanitize, or Pure Cycle, wash modes and appear not to be functional. The Sanitize and Pure Cycle wash cycles have target temperatures to assure washer performance. If the water temperature doesn't meet the target temperature during the wash cycle, the washer will automatically add extra time to allow the heater to bring the water to the programmed, or target temperature. In this stage, the displayed time will pause and hold until the heating operation has been completed. It is at this point that the customer may feel that operation has stopped. (The maximum added programmed time is 30 minutes).
