LG Front-Load Washer Error Codes: OE, IE, UE, dE and More

LG front-load washer codes from LG's official error-code list, checked for the WM3400CW, with the meaning, first step and source for each.

10GUIDES IN THIS COLLECTION

Short answer: The LG front-load washer codes people search most are OE (won't drain), IE (won't fill), UE (unbalanced load), LE (won't spin) and dE (door). The table gives LG's own meaning for each code on its official front-load washer code list, checked for the WM3400CW, with the first step and a link to the full guide.

Scope and model check

This collection is scoped to the U.S. LG WM3400CW 4.5 cu. ft. front-load washer family, using LG's exact WM3400CW product-support page as the model boundary and LG's current front-load washer error-code guide as the code reference. The table below lists the codes on LG's list that apply to this family, including status messages such as tcL and CL. Other LG washers, washer-dryer combos and regional models can use different labels or meanings; match the complete model number and its manual first.

These messages are prompts for safe checks, not proof that a particular part has failed. Do not open the cabinet, probe energized circuits, bypass the door lock or replace a board, motor or sensor from a code alone.

How to use this collection

Photograph the display, copy the model and suffix from the rating label, and read the manufacturer guidance before buying anything. Start with the visible, reversible checks in the matching article. If the message returns after LG's reset or cleaning step, arrange qualified service; a temporarily cleared display does not establish that the underlying fault is repaired. For the companion laundry pair, see the LG DLE3400W front-load dryer code hub.
