Also check the sensor it may be disconnected or defective. The Main PCB may also be defective 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. bE 25 Check the water valve wiring harness. Water Supply Error nF 3 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 nF1 Correct Hot/Cold hose connections System Error SF1 SF2 SF3 Replace PCB Error Type Error Mode LED Details LCD Check for Foreign material entering the pump or hoses. Drain Error nD 1 Check to make sure the wiring harness is connected properly. Check the water pump terminal . Check for freezing Power Error 2E 91 92 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) PF Momentary Power Failure AE Check the wire connections and terminal contacts between the sub and main PBAs. Communication Error 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. EEPROM Fault. 11 Switch Error E2 15 (Main Relay Error) Go to “EEPROM Clear Mode” If display shows “FAiL”, Replace Machine Control Board 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. SR 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 dS 22 (Before operation) Door Error dL 18 (During operation) LO 2 (Unlock Fail) FL 4 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 Error Type Error Mode LED Heater Error Details LCD 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. Hr 36 (Heater Relay) An Hr error occurs if the steam heater, is faulty, replace it. Overflow error 9E1 EMC Filter issue or a noise spike from an external device OE E 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 The washing heater temperature sensor in the tub has an error. Check the connections for the washing heater temperature sensor connector. Temperature Sensor Error 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. dC 10 Silver Care Kit 7E (Silver Care PCB) Failure. Mems or Har- Foaming Detected Check Silver Care PCB ,Main PCB & Wire-harness 8E Check MEMS PCB ,Main PCB & Wire-harness 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.) SUdS Sd 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 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. Water valve connections for the Detergent Drawer Items Packed With Washer BOLT-SPANER (10-13mm Wrench) DC60-40146A ASSY HOSE WATER DC97-15691A ASSY HOSE WATER DC97-15692A MANUAL-BOOK DC68-02535A CAP-FIXER DC67-00307A HOSE-HANGER DC62-10278A 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. It is normal for a small amount of water remaining in Detergent Drawer after it completes washing. Bleach is usually flushed out into 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 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.
