Product review (1 stars): Good water pressure needed for clean dishes
I would strongly agree with the previous rating.  We purchased this dishwasher about 4 months ago and  we have had the same problems.  Sometimes the soap never leaves the dispenser and the top rack is always dirty.  I found that rinsed plates on the bottom will come clean as well as the silverware, but anything plastic will have a film of soap (if dispensed during cycle) or greasy film from other dishes.  It probably is a water pressure issue, but that doesn't help us get dishes clean now.  Maybe the manual should give a recommended spi for this machine to work properly.
