description of buttons?

I have a integrated diplomat dishwasher. The problem being firstly I have two lights that flash constantly. these are the power and super wash lights. secondly we went to clean today via a bottle of fluid of which you leave upside down in a cycle. The top of the bottle is wax and did not melt which leads me to believe that the dishwasher isn't getting up to temperature. I have just moved in and the unit was left in house. It was working fine but i wasn't left any instructions can anyone help???
