Tim for Model Number SHEM78W55N/10 Bosh Dishwasher Symptom: Not enough water is flowing into the dishwasher, and there is not enough pressure in the spray arms to make them spin. The problem is slowly getting worse. At first, only the top spray arm would not spin. Now, neither spray arm spins. Manually adding half a gallon of water to the dishwasher is an effective work around, but it requires timing the cycle properly. Presumably, this indicates that the pump is working. The water supply line is not kinked. This symptoms remain whether or not the dishwasher is loaded. The spray arms (00745856, 00744883) are not clogged. The water inlet system (00744882) is in good shape. The water inlet valve (00628334) was already replaced, but this had no effect on the symptoms.

Otherwise, I am leaning towards replacing the control as the fill time has gone out somehow. The control part number is 12016881. Read More...
