I have an LG dishwasher, not this particular model, but the LDF 5545. The first prerinse is like this and yes it does look weak, but there is a reason for it, not to overload the filtration system. In my machine there are 4 prerinses before the main wash. In the 3rd and 4th prerinses the wash motor ramps up speed and scours each rack alternating between racks. The main wash uses a low, medium and high pressures The low pressure sprays the dishes and lets the detergent soak into the soils on the items in the load, then the dishwasher ramps up pump speed and then washes each rack at medium pressure. In the middle of the wash cycle the pump stops and ramps up pressure to the max and then scours the hell out of everything in the load. Mine has the Quad Wash arm and the arms sweep in a counterclockwise movement. The water reaches to the ceiling of the tank with quite a bit of force.
The top video is not how these dishwashers operate all the time.
