There is no removable filter as such in the machine.

Besides the two main spray arms there is also a spinner arm (part #3 upper wash and rinse parts diagram) which is basically a 3rd spray arm
Try placing the 3 spray arms in a remembered position and then start the machine. Allow it to fill and then start to briefly wash and then open the door to stop the machine (be careful, open slowly to prevent water coming out) and check the position of the spray arms to see if they have moved at all. It is the pressure of the water being pumped out of the holes in the spray arms that causes them to turn and therefore distribute the water evenly over the dishes.

Are the dishes drying OK?

Do they clean properly if you select a hotter wash cycle option?
