Bosch Dishwasher shu9915 problems

Just recently, my bosch dishwasher stopped completely cleaning the dishes...especially the top rack. I pulled the arms, made sure they were clean. Cleaned the filters. Cleaned the screen insert in the inlet valve...did not check with ohm meter. Seems like it doesn't fill very much and if I open the door after it is running for about 2-3 minutes the water only feels warm, not hot. Not sure what my next step is. Possible float or pump issue? Any thought? Your help is appreciated.
