LG bE fault codewhat it means and how to fix it
Oversudsing, and LG name the culprit outright: liquid dish soap. Their published remedy involves a bowl of milk, which sounds like folklore but is in the manual.
Before you start
What bE means
LG do not hedge on what causes bE. Their manual gives it as oversudsing caused by improper detergent, such as liquid dish soap, which is refreshingly direct — most manufacturers describe the symptom and leave you to work out that somebody put washing-up liquid in the machine. LG’s remedy is where it gets interesting, because alongside the expected instruction not to use hand dishwashing liquids, they publish a method for killing the suds that sounds like something a neighbour would tell you: put milk in a bowl on the rack and run a cycle. It is in the owner’s manual, not on a forum. The chemistry is real enough — milk fats break down the surfactant foam faster than plain water rinses will — and it saves running four or five empty cycles. The reason LG bother publishing a remedy at all is that suds are more than a nuisance in a dishwasher. Foam cushions the spray so nothing gets clean, and it starves the circulation pump, which starts pulling air. In a bad case it climbs over the tub and reaches the base of the machine, at which point you are dealing with a leak code instead of a free fix.
What causes it
| Cause | What is actually happening | How likely |
|---|---|---|
| Washing-up liquid put in the machine | LG name it directly as improper detergent such as liquid dish soap. This is the cause the overwhelming majority of the time. | Common |
| Soapy items loaded without rinsing | A pan that has been soaking in hot suds and goes straight in carries enough detergent to foam an entire cycle. Nothing went in the dispenser, so the cause is easy to miss. | Common |
| Too much dishwasher detergent | Possible with powder, particularly in a soft water area where the dose should be smaller than the packet suggests. | Occasional |
| Rinse aid dispenser leaking | A dispenser releasing continuously rather than at the right point produces foam that keeps coming back after you have cleared it. | Occasional |
What to try yourself
Open the door and look for visible foam. If it is there, the cause is confirmed and no part has failed.
Scoop out what foam you can reach, then close the door and run a rinse programme with no detergent whatsoever.
If the suds persist, try LG’s own method: put milk in a bowl on the lower rack and run a cycle. The fats break the foam down faster than rinsing alone.
Check the detergent dispenser for washing-up liquid residue and check the rinse aid dispenser is not overfilled or weeping.
Rinse anything that has been soaking in soapy water before it goes in the machine in future.

Common questions about LG bE
Milk in a bowl? Is that a real instruction?
It is in LG’s UK owner’s manual as their published remedy for this code, which is why we are repeating it. The fats in milk break down surfactant foam more effectively than water, so it clears in one cycle rather than several.
Nobody put anything in the dispenser. Where did the foam come from?
Almost always from something loaded still coated in washing-up liquid — a pan left to soak, or a dish rinsed in a sink of suds. The detergent never went near the dispenser, which is exactly why the cause gets overlooked.
Is the machine damaged?
No. bE is the machine noticing conditions it cannot wash in and stopping. What you want to avoid is running full cycle after full cycle while it is still foaming, because badly foaming water can escape the tub and reach the base, and that turns a free problem into an engineer’s visit.
