usually on this model when the control unit ( bosch part # 266746 ) is bad , burnt relay on the board, it will get stuck cause heating has not occured and temp never achieved. need to determine if there may be a suds problem in the d/w .. run it on an economy program with very little detergent ( 15 ml or less ) ... Never pre-rinse, especially with a sponge w/ soap on it (remember SOAP is a d/w 's greatest enemy !! ) And make sure enough water is coming into the d/w.. if you have a clogged inlet valve , you may not be getting enough water and that will cause a louder circ pump as well as a poor heating condition. This will cause the d/w to "hang-up" at 26 , 13, 11 or 1...
