Water slowly flooding steam vent fan assembly.

I’m sorry to hear that you’re experiencing a leak in your LG dishwasher. Water in the bottom of your LG dishwasher may be due to a clogged drainage system or drain basket, a loose connection around the 90 degree elbow joints and water supply line, or using the wrong detergent, overloading the machine, or leaking hoses.

LG USA Support Video Tutorials provides a video tutorial on how to fix common leaking issues with LG dishwashers. The video suggests that if you notice leaking coming from the bottom of your LG dishwasher, a loose connection around the 90 degree elbow joints and water supply line may be the result for leakage. If there are no visible signs of leakage, take a dry paper towel and touch around the water supply line in the 90 degree elbow joint. Wet spots on a towel will indicate leaking. The 90 degree elbow joint is attached to the inlet valve and the water supply line is attached to the elbow joint.

I hope this helps!
