bE
LG bE on a dishwasher: oversudsing
Risk level
Low
Usually safe to check without specialist tools.
Urgency
Low
Quick answer
LG explains that bE stands for bubble error: the dishwasher detects oversudsing and stops to prevent leaks. It usually comes from using dish soap or too much detergent. Do not use dish soap and cut the dose.
Safety first
Stop and check this first
- Do not use dish soap in the dishwasher: LG warns that it causes leakage, and water outside the appliance is close to mains power.

What a technician must be able to justify
A technician is coming
These are the steps they must carry out and show you. Tick them as they work: if steps are skipped, do not accept a part swap.
These are not instructions for opening or handling the equipment yourself. They are the checks that should support a technical conclusion.
Diagnosis of bE without suds
What they doIf bE appears without suds, the technician checks, with the appliance unpowered, the system that detects suds and compares it with LG specification.
They must show youwhat was found, with a photo or measurement.
In writingthe diagnosis, any replaced part and its reference.
Test after the visit
What they doThe technician runs a programme with a normal dose and checks bE does not return.
They must show youthe finished programme with no code.
In writingthe test and the date.
Before accepting a part or repair
Nothing has been shown yet. Do not accept a part swap based on the code alone.
Checks and evidence, step by step
Follow the documented order. An error code identifies the affected system, but it does not prove by itself which part has failed.

No special tools
Procedure
- Who:
- you.
- How:
- run the dishwasher empty and without detergent, as LG suggests.
- Result that matters:
- whether suds and bE appear.
- If there are suds and bE:

Remove suds with milk
No special tools
Procedure
- Who:
- you.
- How:
- set rinse aid to L0, add no detergent, place a bowl with 200 ml (7 oz) of milk in the middle of the upper rack and select Standard with Extra Dry and Rinse. Repeat if suds remain and reset the rinse aid level afterwards.
- Result that matters:
- a tub free of suds.
- If the suds clear and bE does not return:
- that solves it.
- If suds remain after repeating:
- request service.
- Evidence to keep:
- how many times you repeated the cycle.

What it means
According to LG, bE is a bubble error: the appliance shows bE when oversudsing occurs, which prevents leaks. LG gives two causes: using hand dish soap and adding too much detergent. It recommends powdered or solid dishwasher detergent, or only a small amount if liquid, and gives a milk method to remove the suds. If bE appears without suds, LG asks for service: foam is then ruled out and the code does not say what has failed.

Symptoms and causes
Probable causes · in order
- Hand dish soapCommon
LG warns that dish soap causes leakage. The test without detergent or dishes confirms it: if it still suds and shows bE, residue of the wrong product remains.
Evidence: [LG Dishwasher] Guide to Error Codes
- Too much detergentCommon
Especially liquid detergent. You can tell because bE stops once you cut the dose or switch to powder or tablets.
Evidence: [LG Dishwasher] Guide to Error Codes
- bE without sudsPossible
If the code appears with no visible suds, LG asks for service. Detergent no longer explains it.
