Name: LG WM6700HBA
Brand: LG

Question 1

What does error code C01 mean on LG WM6700HBA?

Accepted Answer

LQC Test Mode - Wi-Fi module OK, program version indicator. Cause: No problem with Wi-Fi module; indicates Wi-Fi program version.

Question 2

What does error code dE mean on LG WM6700HBA?

Accepted Answer

Door Open Error - door not properly closed or locked. Cause: Connector to door switch or main PWB disconnected; Latch hook spring not actuating; No clicking sound when START/PAUSE pressed (PCB assembly fault); Door switch assembly broken.

Question 3

What does error code Ed1 mean on LG WM6700HBA?

Accepted Answer

ezDispense Detergent Pump Error - detergent injection pump failure. Cause: Connector to detergent/softener pump disconnected or disassembled; Detergent/softener pump resistance outside 22-42 Ohm range (pin 1 to pin 3, +/-10%); Detergent/softener is hardened/solidified in pump.

Question 4

What does error code Ed2 mean on LG WM6700HBA?

Accepted Answer

ezDispense Detergent Dispense Sensor Error. Cause: Connector not well connected; Wire cut or damaged.

Question 5

What does error code Ed3 mean on LG WM6700HBA?

Accepted Answer

ezDispense Softener Pump Error - softener injection pump failure. Cause: Connector to softener pump disconnected; Softener pump resistance out of range; Softener hardened in pump.

Question 6

What does error code Ed4 mean on LG WM6700HBA?

Accepted Answer

ezDispense Softener Dispense Sensor Error. Cause: Connector not well connected; Wire cut or damaged.

Question 7

What does error code Ed5 mean on LG WM6700HBA?

Accepted Answer

ezDispense System Error - automatic detergent injection pump connector fault. Cause: Automatic detergent injection pump connector missing or poor contact at Sub PCB Wh6 (1pin, 3pin).

Question 8

What does error code FE mean on LG WM6700HBA?

Accepted Answer

Over Flow Error - water level too high, possible inlet valve failure. Cause: Air chamber or pressure tube clogged (water level frequency below 21.3 kHz); Inlet valve open continuously when power not applied (faulty valve); Main PWB assembly causing inlet valve to stay open.

Question 9

What does error code IE mean on LG WM6700HBA?

Accepted Answer

Inlet Valve Error - water supply problem detected. Cause: Water level frequency below 24.6 kHz (air chamber or tube clogged); Filter inlet valve clogged with foreign material; Inlet valve connectors broken or loose; Resistance of inlet valve assembly outside 0.8-1.2 kOhm range; Inlet valve connector voltage 120V DC indicating failed valve; Connector to MAIN PWB disconnected (NA4, BL6, RD6); Electrical connection incorrect (main harness fault); Water level frequency still below 24.6 kHz after connector check (pressure switch).

Question 10

What does error code LE mean on LG WM6700HBA?

Accepted Answer

Locked Motor Error - motor cannot rotate or is stalled. Cause: Motor drive connector (RD4) disconnected or disassembled; Wire from motor to main PWB damaged; Rotor magnet cracked; Stator resistance (U-V, V-W, W-U) outside 5-15 Ohm range; IPM (Intelligent Power Module) in controller faulty.
