The Float Assembly is an OEM replacement part for LG dishwashers. It is a sensor located inside the dishwasher that monitors water levels during wash cycles. The float assembly precisely indicates water levels to the control system to determine adequate water is available throughout the cleaning and rinsing functions. Proper water level detection is crucial for achieving sparkling clean dishes. Causes of a faulty float include mineral buildup on sensors overtime, cracks or leaks developing, and damage to electrical wiring from impacts. Symptoms of a bad float assembly include: Incomplete or inefficient wash cycles due to low water levels Water remaining in the bottom of the tub after a cycle Drainage issues related to inaccurate water level readings Error codes related to improper filling and draining of water This OEM LG part is also compatible with some Sears/Kenmore models.Part Number 4769DD2001A (AP4437896) replaces 5214DD3002A, 1267583, AH3523437, EA3523437, PS3523437.
