Check the water supply hose for any clogs, kinks, or freezing. Ensure there are no obstructions preventing water from entering the dishwasher. Inspect the water inlet valve to make sure it is functioning properly and allowing water to flow into the dishwasher. Clean the filters in the dishwasher to remove any debris that may be blocking water flow. Ensure the drain hose is not clogged, as drainage issues can also trigger a 6E error code. Use only automatic dishwasher detergent and avoid using regular dish soap, as excessive suds can cause leaks and error codes like bE. If the issue persists, level the dishwasher and consider seeking professional service from an LG technician.
