LG Dishwasher error code bE
bE
What it means
Bubble error - too much foam inside the dishwasher.
Likely causes
- A regular handwash or liquid dishwashing detergent was used, which can generate excessive bubbles and cause leakage to the outside
Safety first: switch the appliance off and unplug it (or turn it off at the circuit breaker) before you check anything. If water is involved, close the water supply valve too. Never open panels or touch internal wiring. Anything that involves gas lines, refrigerant or sealed systems, or mains-voltage wiring is a job for a professional - not a home fix.
Safe first checks
- Do not use hand dishwashing liquids - only use detergents designed for automatic dishwashers
- Run a short cycle with no detergent and no dishes to help clear excess suds - LG Support's advice for repeated bE codes
- Make sure the dishwasher is properly levelled
When to call a pro
If bE returns even with the correct detergent and a level machine, ask LG Support to review it.
Repair or replace?
Try the safe checks first - many codes clear with a clean filter, a straight hose or a balanced load, and those cost nothing. If the code comes back, a service call typically costs $50-$150 for the visit and diagnosis (Angi puts an average service call at $50-$100; Sears lists a $90-$150 diagnostic fee). Get the full repair quote before you decide. If the machine is old and the quote is a large part of the price of a new one, replacing usually makes more sense than repairing.
