LG Dishwasher bE Error Code

Too many suds. Here is what it means and how to clear it, easiest fix first.

Easy DIY fix

The dishwasher sensed excess foam and stopped to prevent a leak. It is usually caused by hand dish soap, too much detergent (especially with soft water) or an unlevel unit.

Safety first: unplug the dishwasher (or switch off its breaker) before touching filters, hoses or panels. If you smell burning or gas, or see water near the outlet, stop and call a professional.

How to fix LG bE

Switch detergent
Use only automatic dishwasher detergent. If you use a liquid, use less of it, or try powder or tablets instead.
Knock down the suds with milk
Set the rinse aid level to L0 and add no detergent. Put a shallow bowl with about 7 oz (200 ml) of milk in the middle of the upper rack and run a Standard cycle with the extra dry and rinse options. Repeat if suds remain, then set the rinse aid back to its usual level.
Check level and reset
Make sure the dishwasher is level side to side and front to back. Then reset the power at the breaker and run a cycle with proper detergent.

When to call a technician

If bE appears when there are no suds in the tub, the sensing system may be faulty and LG service should look at it.
