Not sure if it's this machine or the model itself but problems abound

We've owned this dishwasher for two years and have had to repair it ourselves or have the repair man come fix it no less than ten times. We've had everything from the filter where the water is let into the machine clog up to the motor jam to debris sticking in the chopping blades to no water pressure in the arm at the top and now it isn't draining properly. I'm about to give up on this thousand dollar machine and wash them myself at this point. Sears claimed all problems were our fault (dirty water lines, not rinsing dishes) so we have paid for all repair out of pocket and now the waranty is over. When it isn't clogging or jamming the machine cleans great and it looks great, just a pain because it doesn't work a lot of the time.
