On the covered LG dishwasher platform, bE means a bubble error — LG's own wording. LG states the dishwasher displays bE when oversudsing occurs, deliberately, to prevent leaks. LG names two causes: dish soap used instead of dishwasher detergent, and too much detergent. First, check what was put in the dispenser — LG is explicit that dish soap causes leakage and must not be used.
Differential
Likely causes of “LG dishwasher code bE”, and how to tell them apart
- 1
Dish soap used instead of dishwasher detergent
What separates it Suds fill the tub and bE appears, which points to dish soap used instead of dishwasher detergent
How to confirm LG says dish soaps cause leakage; use only detergent designed for dishwashers
- 2
Too much detergent
What separates it Suds appear with correct detergent and a heavy dose
How to confirm When using liquid dishwasher detergent, use only a small amount; LG recommends powdered or solid detergent
- 3
A fault with no suds present
What separates it bE shows and there are no suds after a rinse-only run
How to confirm If the error shows without suds, LG says to request service
Before you touch a setting
Record this first — changing settings destroys the evidence
- The exact characters shown on the display: bE
- What product went into the dispenser and how much
- Whether suds are visible in the tub
- Whether bE appears on a run with no detergent

ReversibleCheck what was put in the dispenser — LG is explicit that dish soap causes leakage and must not be used.
Correct only the documented fault domain
ReversibleUse only dishwasher detergent, and only a small amount of a liquid one.
Test for oversudsing
ReversibleOperate the dishwasher without adding any detergent and without loading any dishes; if suds and bE occur, LG says the cause is an improper detergent residue.
Set the rinse aid
ReversibleSet the rinse aid level to L0 and do not add detergent.
Run the milk cycle
ReversiblePut a bowl with 200 ml (7 oz.) of milk in the middle of the upper rack, select the Standard cycle with Extra Dry and Rinse, and press Start; repeat if suds remain.
Restore the setting
ReversibleWhen the suds are gone, change the rinse aid level back to its original setting.

When this stops being a self-service repair
- !Do not run more cycles while the tub is full of suds; the leak protection stopped it on purpose
