LG dishwasher bE Bubble Error

Keep getting a “be” error code. I used the correct detergent, tried the milk trick , leveled and turned off the power for 24 hours. I spoke to a rep and they said to run an empty load with just water. Still nothing- code keeps coming up just before drying cycle. How does machine sense over sudsing?. Any luck out there with this issue?
