EEPROM Clear Check: Power off, press Delay Start, Signal, and Power Key simultaneously. This clears all memory, including fault codes, and should be done when a new Main PCB is installed. "Good" indicates success, "FAIL" indicates failure.
Error Codes and Troubleshooting: The manual provides a comprehensive list of error codes (LED and LCD displays) with detailed descriptions and troubleshooting steps.
- LE8 (Water Level Sensor Problem): Check hose (loose, pinched, damaged, clogged), sensor (disconnected, defective), or Main PCB.
- 3E/E3/bE25 (Motor Drive/Hall Sensor Error): Check motor drive connector (loose), hall sensor (disconnected, loose, damaged), foreign object in motor, motor damage, loose stator, overloaded drum, or defective relay/PCB.
- nF3 (Low Water Pressure): Check water valve wiring harness, water supply valve (clogged), water supply, or reversed fill hoses.
- nF1 (Fill Hoses Reversed): Correct hot/cold hose connections.
- SF1/SF2/SF3 (System Error): Replace PCB.
- nD1 (No Draining): Check for foreign material in pump/hoses, wiring harness connection, water pump terminal, or freezing.
- 2E/91/92 (High/Low Voltage Detected): Check operating voltage (under/over), plug receptacle, extension cord use, or Main PBA fault.
- PF (Momentary Power Failure): Indicates a brief power interruption.
- AE (Electronic Control Problem): Check wire connections/terminal contacts between sub and main PBAs, disconnected wires, moisture on sub PCB, or faulty main PCB communication circuit.
- 11 (EEPROM Fault): Go to "EEPROM Clear Mode"; if "FAiL" is displayed, replace Machine Control Board.
- E2/15 (Switch Error/Main Relay Error): Check if power switch or tact switch is stuck, service PBA holding screws are too tight, main PBA switching IC on/off error, or incorrect main relay connections.
- dS22 (Door is open - before operation): Check door switch and latch alignment.
- dL18 (Door was unlocked while washer was running - during operation): Check latch for damage, wiring harness to latch, door switch, main PBA door sensing circuit, or Main PCB operation.

- FL4 (The washer door would not lock - Lock Fail): Verify Main PCB operation.
- Hr36 (Heater/Water Temperature Control Problem): Check for short/disconnected wire in heater circuit, tub contacting heater, frozen water, no water, temperatures above 145C, PBA relay malfunction, or faulty steam heater.
- 9E1 (EMC Filter issue): Indicates a noise spike from an external device.
- OE/E (Water Supply Problem/Overflow): Verify drain is working, water level detection, water valves shut off fully, or water level sensor.
- 29/LE (Temperature Sensor Problem): Check connections for washing heater temperature sensor connector.
- dC10 (Unbalanced Load): Check laundry type, reposition load, remove items, or complete wash cycle.

- 8E (Mems or Harness Failure): Check MEMS PCB, Main PCB, and wire harness.
- SUdS/Sd (Excessive Suds): Normal operation; if persistent, check detergent usage.
Leveling: Ensure the washing machine is level to the floor to reduce redo calls and customer dissatisfaction, as vibrations can shorten product lifetime.
Foot Pads: Use foot pads (DC97-10935A) for walking washers, especially when installing on upper floors, and do not exceed recommended leg adjustment height for stability.
Water Valve Connections: Diagram provided for detergent drawer connections (Main (C), Bleach, Main (H)).
Water Retention: Normal for some water to remain in the detergent drawer after washing. Bleach is flushed out, and the compartment is washed during the rinse cycle.
Touch Up Paints: List of available touch-up paints for various colors.
Installation Location: Do not install in areas where water may freeze, as the washer retains water in its valves, pump, and hoses, which can cause damage.
