LG Washer Error Code bE — What It Means & How to Fix It

What Does This Error Mean?

The bE error means your LG washer detected a stuck or faulty control panel button. A button is either physically stuck or sending a constant signal. The washer stops to prevent unintended operation.

Affected Models

WM3900HWA
WM4000HWA
WT7300CW
Most LG front-load and top-load washers

Common Causes

A button physically stuck in the pressed position
Moisture or detergent residue under a button
Damaged or worn control panel membrane
Electronic fault in the control panel board
Child Lock mode mistakenly activated

How to Fix It

Press each button on the control panel firmly to see if any are physically stuck.

Press and release each one to feel for a button that doesn't spring back.
Wipe the control panel area with a clean, slightly damp cloth.

Detergent splashes can get under buttons and cause them to stick. Let it dry fully.
Unplug the washer for 60 seconds, then plug it back in.

This resets the control board and may clear the error.
Press the Start/Pause button and attempt to restart the cycle.

Watch the display. If bE returns immediately, a button or board fault is confirmed.
If the error persists, contact LG support.

The control panel assembly may need professional replacement.

When to Call a Professional

If cleaning the buttons and resetting the washer doesn't clear the bE error — the control panel or main board may be defective. Panel replacement costs $150–$350 depending on the model. Contact LG support or a certified appliance technician.
