Name: LG WM8900HBA
Brand: LG

Question 1

What does error code dE1 mean on LG WM8900HBA?

Accepted Answer

Door Open Error (variant 1). Cause: Door not fully closed; Loose or broken electrical connections at door switch and PWB assembly; Latch hook spring not adjusted properly; Door switch assembly faulty; PCB assembly defective.

Question 2

What does error code dE2 mean on LG WM8900HBA?

Accepted Answer

Door Open Error (variant 2). Cause: Door switch assembly out of order; Loose electrical connections at door switch and PWB; Latch hook spring misaligned.

Question 3

What does error code EE mean on LG WM8900HBA?

Accepted Answer

EEPROM Error. Cause: EEPROM on main PCB is out of order.

Question 4

What does error code FE mean on LG WM8900HBA?

Accepted Answer

Overflow Error. Cause: Water is overflowing (water level frequency over 21.3 kHz); Air chamber and tube clogged causing false overflow reading; Inlet valve open continuously when power not applied (stuck open); Main PWB defective causing continuous valve activation.

Question 5

What does error code IE mean on LG WM8900HBA?

Accepted Answer

Water Inlet Error. Cause: Correct water level (24.6 kHz) not reached within 8 minutes after water is supplied; Water level does not reach preset level within 20 minutes; Air chamber or tube clogged; Filter inlet valve clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve resistance out of range (spec: 0.8-1.2 kOhm); Connector at MAIN PWB disconnected (NA2, NA4, BL3); Main harness open circuit; Pressure switch faulty.

Question 6

What does error code LE mean on LG WM8900HBA?

Accepted Answer

Locked Motor Error. Cause: Motor drive connector (GY4 on MAIN PWB) disconnected or disassembled; 3-pin male blue connector in MOTOR HARNESS not connected to 3-pin female blue of STATOR ASSEMBLY; Bad or unstable electric contact between 3-pin male blue MOTOR HARNESS and 3-pin female gray connector in MAIN PWB ASSEMBLY; MOTOR HARNESS between STATOR ASSEMBLY and MAIN PWB cut (open circuit); Stator winding resistance out of range (spec: 5-15 Ohm for all phase pairs U-V, V-W, W-V); Rotor magnet cracked; IPM module in controller defective.

Question 7

What does error code OE mean on LG WM8900HBA?

Accepted Answer

Drain Error. Cause: Not fully drained within 10 minutes; Pump motor connector broken or loose; Air chamber or pressure tube clogged; Drain hose kinked, bent, or clogged; Drain pump coil resistance out of range (spec: 10-20 Ohm); Voltage between connectors NA2 pin1 and BL3 pin1 out of range; Foreign material inside drain pump; Drain hose positioned too low or frozen.

Question 8

What does error code PE mean on LG WM8900HBA?

Accepted Answer

Pressure Sensor Error. Cause: Pressure sensor assembly out of order; Water level frequency consistently below 10 kHz or over 30 kHz; Pressure sensor connector broken or loose; Pressure sensor resistance out of range (pin 1 to pin 3: 21-23 Ohm +/-10%); Air chamber and tube clogged; Main PWB defective.

Question 9

What does error code PF mean on LG WM8900HBA?

Accepted Answer

Power Failure. Cause: Power supply interrupted while washing machine was operating and then rapidly restored.

Question 10
