I cannot find any info using the numbers you gave.

You replaced the float and the switch. How did you find those without a model number?

To level it you can usually use the top of the lower rack. This should let you level it side to side and back to front.

Check that the bottom wash arm is OK and all the holes are clear.
Sometimes you can get a crack or a partially plugged hole that will spray water at a weird angle and cause a leak.

Since you replaced the float I am assuming that you cleaned all the parts in that area. They have to be clean to prevent capillary action wicking the water up.

Try opening the door when the unit is full to see if it still leaks.
If it does then carefully check for a small crack of pin hole in the tub.
