bE3
LG Washing Machine
Severity: ModerateWhat Does This Error Mean?
The bE3 error on an LG washer means a button on the control panel is stuck or is being held down continuously. The machine detects that a button has been pressed without releasing for an unusually long time. It stops the cycle to prevent unintended operation. This is often caused by a stuck physical button, moisture behind the panel, or a faulty control board.
Affected Models
- WM3900HWA
- WM4500HBA
- WM3500CW
- WM1333HW
- Most LG front-load washers with electronic control panels
Common Causes
- A button on the control panel is physically stuck in the pressed position
- Moisture or detergent residue behind the control panel causing a button to stick
- Damaged or worn control panel membrane with a key that no longer springs back
- Electronic fault in the control panel circuit board causing false button detection
- Child lock feature activated unintentionally, sometimes triggering bE3 on some models
How to Fix It
-
Press all buttons on the control panel one by one and release each firmly. A button that is stuck in the down position will not spring back like the others. Try pressing it repeatedly to free it from any sticking.
Sometimes a button sticks due to dried detergent residue around the button edge. Gentle pressure can free it.
-
Clean around all the buttons with a damp cloth. Detergent spray, fabric softener, and moisture can seep behind buttons and cause them to stick. Use a slightly damp (not wet) cloth to clean the face of the control panel.
Never spray cleaning products directly onto the control panel. Moisture behind the panel is a common cause of bE3.
-
Unplug the washer for 5 minutes and plug it back in. This resets the control board and clears any false button detection that was stored in memory. Restart and see if the error returns.
If the error does not return, the cause may have been a momentary electrical glitch or a button that was briefly stuck.
-
Check whether Child Lock is activated. On some LG models, Child Lock puts the control panel in a locked state. Holding the Child Lock button for 3 seconds toggles it on or off. The panel display may show 'CL' when Child Lock is on.
bE3 and Child Lock activation can look similar on some models — the panel appears unresponsive.
-
If a specific button is confirmed stuck or the control panel has visible damage (cracked membrane, water ingress), replace the control panel assembly. This is a moderate DIY repair involving removing the top panel and front panel of the washer.
Take photos before disconnecting wiring harness connectors to make reassembly easier.
When to Call a Professional
If cleaning the panel and resetting the washer doesn't fix bE3, the control panel assembly or main control board may need replacement. A control panel typically costs $80–$200 for the part. Labor adds $100–$200 depending on the shop.
Frequently Asked Questions
Why would a button on my washer get stuck?
Over time, the rubber or plastic membrane behind touch-sensitive panels can degrade and lose its elasticity. Detergent residue, grease from hands, and humidity all contribute to sticking. Physical damage — like a heavy object pressing on the panel — can also deform the button mechanism. Regularly wiping the panel helps prevent buildup.
Can water in the control panel cause bE3?
Yes. If water or detergent gets behind the control panel, it can cause short circuits that the board reads as constant button presses. This is one of the more common causes of bE3 on machines in humid laundry rooms or after a nearby leak. Allow the machine to dry thoroughly before use if water has entered the panel area.
Is bE3 covered under LG's warranty?
If the control panel fails due to a manufacturing defect within the warranty period, yes. LG's standard warranty is 1 year parts and labor. If the failure was caused by user-induced water damage, it likely won't be covered. Contact LG customer support at 1-800-243-0000 to discuss your situation.
