Bosh Dishwasher Problem?

I have a Bosh Dishwasher SHX33RF5UC.

One day it just stopped wroking in the middle of a cycle and the water was just standing in the dishwasher.

This unit was only 2-3 month old then,bought brandnew.

I left it be for a 1.5 year. Today I tried fixing it again. I checked the water line and the drain hose,nothing is glogged.I messed around with it for hours pushing buttons and such.

It then just worked again completed a quick wash cylce. I then let it run again and it did fine.

But then it just started to push water in it for 20 seconds and then just stopped when I reset and started over I heard some wierd sounds almost sounded like hard loose particals being "grinded"?

I started it again and it just put in a couple seconds of water then stopped.

Now it has once again stopped all together.

Do you have any ideas what could be wrong with it? If so can you give instructions on how to possibly fix it?Thank You
