What does error code bE mean on a LG dishwasher?

Too many suds (bubble error). The dishwasher detected oversudsing and stopped to prevent leaks.

Can I fix LG code bE myself?

Start with these safe checks: Run the dishwasher empty with no detergent. If suds and bE come back, the detergent was the cause. LG's fix: set rinse aid to L0, put a bowl with 7 oz of milk on the upper rack, and run a Standard cycle with Extra Dry and Rinse. Repeat if suds remain, then reset rinse aid. If bE appears with no suds, request service.

When should I call a technician for code bE?

If bE appears with no suds, request service. Unplug it or switch the breaker off before you remove any panel. Don't test or replace wiring, control boards, heating elements or motors under power. If you see scorching, smell burning, or the breaker trips again, leave it off and call a qualified appliance technician or electrician.
