lg | dishwasher – Oversudsing Error – Too Much Detergent
Error Codes (bE): Troubleshooting, Fixes & Prevention Tips explained below.

What Does Oversudsing Error Mean❓

The Oversudsing Error indicates that too much detergent or the wrong type of detergent has been used in the dishwasher. This creates an excessive amount of suds, which can interfere with water levels, cause sensor malfunctions, and may lead to leaks or incomplete cycles. Suds can also overflow into the base tray, triggering other safety errors. This problem is often caused by using regular dish soap instead of dishwasher detergent or exceeding the recommended amount.
