Analysis by Lukas & Team
Troubleshoot the bE error on your LG Smart Dishwasher. Diagnose suds or bubble problems for reliable performance in Canadian homes.
Use only detergents specifically formulated for automatic dishwashers. Avoid hand soap or dish soap, as these create excessive suds.
The service menu access sequence varies by model. Consult the service manual or search online forums for the specific key combination for your dishwasher model. Exercise caution, as incorrect settings can damage the appliance.
You can often find service manuals online through LG's website or third-party appliance repair resources. Search by your dishwasher's model number.

The LG Smart Dishwasher uses a turbidity sensor to detect soil levels and adjust the wash cycle accordingly. The 'bE' error typically indicates an issue with the foam or suds level interfering with the sensor's readings. The dishwasher's control board monitors signals from the turbidity sensor (analog voltage, typically 0-5V DC) and pressure sensors to determine water fill and drainage. Communication between the control board and the motor control inverter occurs via serial communication. OTA firmware updates are delivered over Wi-Fi (2.4 GHz band preferred).
A temporary bypass of the turbidity sensor can sometimes be achieved through the service menu (consult the service manual for entry sequence, varies by LG model) to allow the dishwasher to complete a cycle. This is a diagnostic measure only and should not be a permanent solution.
