LG Dishwasher Error Code bE — Button Stuck / Input Error
What this means
The bE error code means one of the dishwasher's control panel buttons is stuck in a pressed position or is continuously sending a signal to the control board. This can be caused by a physically stuck button, moisture inside the control panel, a faulty membrane switch, or a control board input failure.
Step-by-step fix
3 stepsPress each button individually
Press every button on the control panel one at a time, pressing firmly and releasing. A button that feels sticky, doesn't click, or stays depressed is the culprit. Try to free it by pressing it several times.
Spilled liquids or food can cause buttons to stick. Clean the panel surface thoroughly.
Power cycle the dishwasher
Unplug the dishwasher for 10 minutes. This clears the control board's memory of the stuck input. Plug it back in and see if the error clears.
Inspect the control panel membrane
If the error persists, the membrane switch overlay (the flexible layer with the button graphics) may be damaged or have moisture underneath. On some models, you can carefully peel back the membrane to check for moisture and let it dry.
Do not use sharp objects on the membrane — it tears easily and is expensive to replace.
When to call a professional
If a button remains stuck or the membrane switch is damaged, the control panel assembly may need replacement. A technician can order and install the correct panel for your model.
