I have a Bosh dishwasher that looks fairly new, and was installed in a kitchen remodel that was supposed to have been done in mid to late 2004.

I see a model number SHU5316UC/U06 on a tag on the right edge of the door. I see no other model number or identifying tag or model number. The name Bosch is on the top left outside face of the door, but that is it.

The issue is that one day the drain stopped up, then after I cleared the drain of assorted junk, it has not washed dishes since. The machine comes on, throws out cool water (the water no longer gets hot) and eventually goes through a cycle, and does not clean the dishes.

Any ideas on what the problem is?
