Name: LG WM8100HWA
Brand: LG

Question 1

What does error code dE1 mean on LG WM8100HWA?

Accepted Answer

Door Open Error — door not fully closed or door switch circuit fault.. Cause: Door not all the way closed; Loose electrical connections at door switch and PWB Assembly; Latch hook spring not adjusted properly; DOOR SWITCH ASSEMBLY is out of order.

Question 2

What does error code dE2 mean on LG WM8100HWA?

Accepted Answer

Door Open Error (variant) — door switch circuit fault, same root causes as dE1.. Cause: Door not all the way closed; Loose electrical connections at door switch and PWB Assembly; DOOR SWITCH ASSEMBLY is out of order.

Question 3

What does error code EE mean on LG WM8100HWA?

Accepted Answer

EEPROM Error — EEPROM is out of order. Displayed only when START/PAUSE button is first pressed in Load Test Mode.. Cause: EEPROM chip failure on main PWB.

Question 4

What does error code FE mean on LG WM8100HWA?

Accepted Answer

Overflow Error — water is overflowing; water level frequency is over 21.3 kHz. Note: when FE is displayed, the drain pump will operate automatically to drain water. Power will NOT be turned off automatically.. Cause: Water overflowing — water level frequency over 21.3 kHz; Air chamber or tube clogged; Inlet valve open continuously when power is not applied (stuck open) — replace inlet valve; MAIN PWB ASSEMBLY driving inlet valve continuously.

Question 5

What does error code IE mean on LG WM8100HWA?

Accepted Answer

Water Inlet Error — correct water level (24.6 kHz) not reached within 8 minutes after water is supplied, or does not reach preset water level within 20 minutes.. Cause: Air chamber or tube clogged; Filter on inlet valve clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve resistance out of spec (should be 0.8-1.2 kΩ); Inlet valve connector voltage not 120 V AC; Connector to MAIN PWB assembly disconnected (NA2, NA4, BL3); Electrical wiring incorrect — main harness fault; Water level frequency still below 24.6 kHz after connector check — pressure switch fault; MAIN PWB ASSEMBLY failure.

Question 6

What does error code LE mean on LG WM8100HWA?

Accepted Answer

Locked Motor Error — motor or motor harness fault.. 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 connector of stator assembly; Bad or unstable electrical contact between 3-pin male blue connectors in motor harness and 3-pin female gray connector in main PWB assembly; Motor harness between stator assembly and main PWB assembly is cut (open circuit); Rotor magnet cracked; Stator winding resistance out of range (should be 5-15 Ω for U-V, V-W, W-V).

Question 7

What does error code OE mean on LG WM8100HWA?

Accepted Answer

Drain Error — tub not fully drained within 10 minutes.. Cause: Pump motor connector broken or loose; Air chamber, tube clogged, or pressure switch fault causing water level frequency below 25.0 kHz; Drain pump coil resistance out of range (should be 10-20 Ω); Voltage between connectors NA2 pin1 to BL3 pin1 out of range; MAIN PWB ASSEMBLY failure; Drain hose kinked, clogged, or end submerged; Foreign material inside drain pump.

Question 8

What does error code PE mean on LG WM8100HWA?

Accepted Answer

Pressure Sensor Error — PRESSURE SENSOR ASSEMBLY is out of order; water level frequency consistently below 10 kHz or over 30 kHz. Note: PE error will not disappear when START/PAUSE is pressed; if unresolved within 20 seconds power turns off and error blinks.. Cause: 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 or tube clogged with foreign material; MAIN PWB ASSEMBLY failure.

Question 9

What does error code PF mean on LG WM8100HWA?

Accepted Answer

Power Failure — power supply was interrupted while washing machine was in operation, then power was rapidly restored.. Cause: Power outage or interruption during cycle.

Question 10

What does error code Sud mean on LG WM8100HWA?

Accepted Answer

Suds Error — too many suds detected. Machine adds a Suds Reducing cycle (adds approximately 2 hours to cycle time). If too many suds detected during spinning, machine stops to prevent leaking.. Cause: Excessive or non-HE detergent used; Too much detergent used; Water level frequency below 23.0 kHz during intermittent spin (suds detection threshold).
