Direct answer
On a supported LG dishwasher, bE means excess bubbles or an incorrect detergent condition was detected. Remove hand dishwashing liquid or excess detergent and wipe out accessible foam. Then run an empty rinse using no detergent until bubbles are gone.
What this covers
- LG dishwashers displaying bE
- The code and product type exactly match the official source
- Customer-accessible checks before component replacement
What it does not cover
- ×A similar code on another manufacturer or appliance type
- ×Codes omitted from the exact model manual
- ×Internal wiring, sealed-panel or live-electrical repair
Confirm bE on the exact model
ReversiblePhotograph the complete display, record the model tag and note the cycle stage. Similar-looking codes can mean different things on another product line.
Check the condition named by the code
ReversibleRemove hand dishwashing liquid or excess detergent and wipe out accessible foam.
Correct the remaining user-serviceable cause
ReversibleRun an empty rinse using no detergent until bubbles are gone.
Run one controlled verification
ReversibleUse automatic-dishwasher detergent in the measured amount on the next load. A repeat with no foam can indicate a leveling or sensing issue.
