The unit had a bad heating element. Considering I've only worked on a hand full of Bosch dryers I was having a great time getting to the element. Although the manual you have is not an exact match for this model (basically the control panel looks and is removed differently). I can now familarize myself with these units again. I was hoping to run diagnostics on it and had no tech sheet, so I called our tech support, and as usual got no help from them.
