Hi I am not sure what the model is because it is built in and I don't have a manual. Where do you put the rinse aid. The light is on so I know I need it but don't know where it goes. There is a square container on the door next to where the powder block goes. It has a dial inside with numbers 1-7. There is also another area on the floor of the machine next to the salt container doesn't seem to open though.its white with a few small holes in a circle on the top.
