What bE (Bubble Error) Means
bE stands for bubble error - LG's dishwasher Help Library article explains the dishwasher displays this specifically to prevent leaks when oversudsing occurs, most often from using dish soap instead of proper dishwasher detergent, or simply using too much detergent.
Common Causes of bE (Bubble Error)
- Dish soap used instead of dishwasher detergent
- Too much liquid dishwasher detergent used
- Rinse aid level set too high, contributing to sudsing
🔧 One Safe Check You Can Try
Switch to a detergent formulated specifically for dishwashers (never dish soap meant for handwashing) and, if using liquid dishwasher detergent, use only a small amount - LG recommends powder or solid detergent designed for dishwasher use as a more reliable alternative; to actively clear oversudsing, run the dishwasher empty (no detergent, no dishes) with 200ml of milk placed in a bowl on the upper rack, using the Standard cycle with Extra Dry and Rinse options selected, repeating if suds remain, then reset your rinse-aid level back to normal afterward.
⚠ Why You Shouldn't Go Further Than That
- If bE keeps appearing even when you're confident no oversudsing occurred (no dish soap, correct detergent amount), LG's guidance is to request service rather than keep adjusting detergent - a persistent bE without visible suds points to something else being misread as oversudsing.
