This is an old model bought in 2007 but we have used it regularly and it is still spotless and cleans beautifully. We kept the instructions so had no problem operating it unlike the other reviewer. It has a 30 min cycle for if washing straight after use with few pans and a 70 min cycle for normal use. we have never needed the longer cycles. It works best with separate dish-washing powder and rinse-aid. It is quiet. After dinner for 10 people it coped well by just doing 2 cycles of washing and drying. Avoid flimsy plastic things that fall over and retain water.
