Question

I have pulled the dishwasher out and checked hose. No kink in line. I have taken cleaned out dishwasher and no clog. I poored water into dishwasher and it drains from the bottom not throught drain hose. I have checked the drain hose on the bottom of the dishwasher and to no avail....I don't know what is causing this issue....can you help me out with this?

LG-14AW3 Dishwasher does not drain properly and then powers itself off mid cycle. Filters are clean and there are no kinks in the drain hose. How do I fix this and will it be very expensive.
Thanks
