Does anyone know what these parts belong to?

LG LDF7551ST getting DE (drain error) - everyone calls it OE.

I removed the drain hose that is connected to the disposal and blew into it and the water bubbled up. Cleaned filter, ran on quick setting and it indeed generated the DE error again. Without removing dishwasher I removed kickplate to see drain pump right in front.

I removed drain hose from pump and noticed a 1 inch long piece of grey plastic and a 3/4" black circular piece of flat rubber and has a handle of sorts as if it were to be secured onto something. Does anyone know what these parts belong to? Not sure if they dislodged when I blew into the drain hose?

I am not certain that these items are from the internal components of this dishwasher but maybe they were causing drain issues? I am about to run it once again - I will report back to let you know what happens.

Answer this question I have this problem too

Is this a good question?

So I ran the dishwasher without incident. I am guessing that the circular flat rubber piece is from the garbage disposal? Not sure where the piece of grey plastic is from although it is the same plastic and color as the dishwasher rack.

That flat piece of rubber is the anti backflow flap that most likely came either just before or just after the drain pump, and the little "handle" is its mounting hinge. You will have to look in the end of the hose that you disconnected or the piece of grey plastic pipe to see if there's a corresponding molded in spot for that hinge. If you don't find a mounting spot there, then it must be located in where the water enters the drain pump from the tub.
