Name: LG WM9500HKV
Brand: LG

Question 1

What does error code dE1 mean on LG WM9500HKV?

Accepted Answer

Door Open Error (variant 1). Cause: Door not all the way closed; Loose electrical connections at door switch and PWB assembly; Door switch assembly out of order; Latch hook spring not adjusted properly.

Question 2

What does error code dE2 mean on LG WM9500HKV?

Accepted Answer

Door Open Error (variant 2). Cause: Door not all the way closed; Loose electrical connections at door switch and PWB assembly; Door switch assembly out of order.

Question 3

What does error code EE mean on LG WM9500HKV?

Accepted Answer

EEPROM Error — EEPROM out of order. Cause: EEPROM chip on main PWB out of order.

Question 4

What does error code FE mean on LG WM9500HKV?

Accepted Answer

Overflow Error — water is overflowing (water level frequency over 21.3 kHz). Cause: Water overflowing — water level frequency over 21.3 kHz; Air chamber and tube clogged; Inlet valve open continuously when power not applied (faulty inlet valve); Main PWB causing inlet valve to stay open.

Question 5

What does error code IE mean on LG WM9500HKV?

Accepted Answer

Water Inlet Error. Cause: Correct water level (24.6 kHz) not reached within 8 minutes after water is supplied; Preset water level not reached within 20 minutes; Air chamber or tube clogged; Filter on inlet valve clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve resistance out of range (should be 0.8-1.2 kΩ); Connector to MAIN PWB disconnected or disassembled (NA2, NA4, BL3); Pressure switch faulty (water level frequency below 24.6 kHz after connector check); Main harness open circuit; Main PWB assembly faulty.

Question 6

What does error code LE mean on LG WM9500HKV?

Accepted Answer

Locked Motor Error. Cause: Motor drive connector (GY4, 3-pin male white) not connected to stator assembly; Poor electric contact between motor harness connector and MAIN PWB 4-pin female white connector; Motor harness between stator assembly and MAIN PWB cut (open circuit); Hall sensor out of order or defective; Rotor magnet cracked; Stator winding resistance out of range.

Question 7

What does error code nE mean on LG WM9500HKV?

Accepted Answer

Wi-Fi Error — Wi-Fi modem not connected. Cause: Wi-Fi modem not connected to network.

Question 8

What does error code nF mean on LG WM9500HKV?

Accepted Answer

Wi-Fi Error — Wi-Fi modem self-check function error. Cause: Wi-Fi modem self-check function error — internal module fault.

Question 9

What does error code OE mean on LG WM9500HKV?

Accepted Answer

Drain Error — not fully drained within 10 minutes. Cause: Pump motor connector broken or loose; Air chamber, tube clogged, or press switch issue (water level frequency below 25.0 kHz); Drain pump coil resistance out of range (should be 10-20 Ω); Voltage between connectors NA2 pin1 and BL3 pin1 out of range; Main PWB assembly faulty; Drain hose kinked, frozen, or positioned too low; Foreign material inside pump.

Question 10

What does error code PE mean on LG WM9500HKV?

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 should be 21-23 Ω ±10%); Air chamber and tube clogged; Main PWB assembly faulty.
