How do I fix error code IE on a LG washers?

1. undefined: Confirm IE is displayed on panel. 2. undefined: Press WASH/RINSE and DELAY WASH buttons simultaneously and check if water level frequency is below 24.6 kHz. If YES → check air chamber and tube for clogging. 3. undefined: If frequency is OK → check if filter inlet valve is clogged with foreign material. If YES → clean or replace the filter. 4. undefined: If filter is OK → check if inlet valve connectors are broken or loose. If YES → reconnect or repair the connector. 5. undefined: If connectors are OK → measure resistance between each terminal of inlet valve assembly. Expected: 0.8-1.2 kΩ (refer to section 9-5, inlet valve assembly). If resistance is out of range → replace the INLET VALVE ASSEMBLY. 6. undefined: If resistance is OK → check voltage at inlet valve connector. Expected: 120 V AC at all terminals of INLET VALVE ASSEMBLY while power is on. If voltage is correct → replace the INLET VALVE ASSEMBLY. 7. undefined: If voltage is not present → check if connector to MAIN PWB assembly (NA2, NA4, BL3) is disconnected or disassembled. If YES → reconnect or repair the connector. 8. undefined: If connector is OK → verify electrical connection is correct per section 9-5 wiring diagram (page 41). If NOT correct → replace the MAIN HARNESS. 9. undefined: If wiring is correct → after checking connector, press WASH/RINSE + DELAY WASH; if water level frequency is below 24.6 kHz → check the PRESSURE SWITCH. 10. undefined: If all above are OK → replace the MAIN PWB ASSEMBLY. 11. undefined: Installation safety checklist: verify no water tap leakage, no freezing, no hose entanglement, no water shortage, no hose shrinkage, no supply hose leakage.

Error Code IE

Water Inlet Error — correct water level (24.6 kHz) not reached within 8 minutes after water is supplied, or preset water level not reached within 20 minutes.

Moderate

Address soon - your appliance may not work properly

What This Means

Air chamber or tube clogged; Inlet valve filter clogged with foreign material; Inlet valve connectors broken or loose; Inlet valve assembly resistance out of range (should be 0.8-1.2 kΩ); Connector to MAIN PWB assembly (NA2, NA4, BL3) disconnected; Incorrect electrical connection (wiring harness); Water level frequency below 24.6 kHz indicating overfill issue; Pressure switch failure

How to Fix

1
Confirm IE is displayed on panel.
2
Press WASH/RINSE and DELAY WASH buttons simultaneously and check if water level frequency is below 24.6 kHz. If YES → check air chamber and tube for clogging.
3
If frequency is OK → check if filter inlet valve is clogged with foreign material. If YES → clean or replace the filter.
4
If filter is OK → check if inlet valve connectors are broken or loose. If YES → reconnect or repair the connector.
5
If connectors are OK → measure resistance between each terminal of inlet valve assembly. Expected: 0.8-1.2 kΩ (refer to section 9-5, inlet valve assembly). If resistance is out of range → replace the INLET VALVE ASSEMBLY.
6
If resistance is OK → check voltage at inlet valve connector. Expected: 120 V AC at all terminals of INLET VALVE ASSEMBLY while power is on. If voltage is correct → replace the INLET VALVE ASSEMBLY.
7
If voltage is not present → check if connector to MAIN PWB assembly (NA2, NA4, BL3) is disconnected or disassembled. If YES → reconnect or repair the connector.
8
If connector is OK → verify electrical connection is correct per section 9-5 wiring diagram (page 41). If NOT correct → replace the MAIN HARNESS.
9
If wiring is correct → after checking connector, press WASH/RINSE + DELAY WASH; if water level frequency is below 24.6 kHz → check the PRESSURE SWITCH.
10
If all above are OK → replace the MAIN PWB ASSEMBLY.
11
Installation safety checklist: verify no water tap leakage, no freezing, no hose entanglement, no water shortage, no hose shrinkage, no supply hose leakage.
