The WATER LEVEL SENSOR ASSEMBLY is an OEM component specifically designed for LG dishwashers. It is an electronic sensor responsible for monitoring and detecting the water level inside the dishwasher tub during each cycle. Precise water level detection allows the dishwasher to optimize water usage and ensure all cycles run as intended. 

Causes of a bad sensor assembly can include the buildup of sediment or minerals on the sensor contacts over time, leading to improper readings. Physical damage from impact could also affect sensor function.

Symptoms of a bad water level sensor assembly include:

• Incomplete or failed wash cycles 
• Error codes related to water issues
• Inability to fill or drain properly
• Flooding or leaks from the dishwasher
