Bubble error. The dishwasher detected too many soap suds, or the unit is not level, so water is sloshing into parts where it should not go.

What causes the be error?
- Wrong detergent (not automatic dishwasher detergent)
- Too much detergent for the load
- Dishwasher not level
- Rinse aid dispenser over-dispensing
How to fix LG be — step by step
Work through these in order, from simplest and safest first. Stop as soon as the code clears.
- Let the suds settle
Cancel the cycle and wait for the foam to die down. Then run a rinse-only cycle to flush the excess suds out. - Use the right detergent and dose
Use only automatic dishwasher detergent, and use less than you think. One tablespoon is often enough for a normal load. - Level the dishwasher
Place a level on the open door or rack rails and adjust the leveling feet until the unit sits even front-to-back and side-to-side. - Flush out detergent residue
Put 3 to 7 ounces of milk in a shallow bowl on the upper rack and run an Auto cycle. The milk fat breaks down soap residue in the tub.
When to call a technician
- bE persists with correct detergent and dose
- Water damage appears under the unit
- The leveling feet are broken or missing
- The rinse aid dispenser leaks constantly
Frequently asked questions
Can dish soap cause bE?
Yes, it is the classic cause. Even a small squirt of hand dish soap creates a foam flood. Never use it in a dishwasher.
Why does leveling matter for suds?
An unlevel tub lets water and foam reach the vent and sensors, which triggers the error even with normal detergent.
Will bE damage my dishwasher?
Occasional foam is harmless once flushed. Repeated flooding can damage electronics, so fix the cause.
