Have model FDB751SCBO. Control knob not advancing. Seems to be in rinse mode continually.

So there are 2 reasons why the timer won't advance when it gets to rinse cycle---either the control board is bad, or the water isn't heating up. If you let it run for house and the water goes to room temperature, then you need to check your heater for continuity as well as the thermostat under the dishwasher for continuity. If either part doesn't have continuity then you need to replace it. The thermostat is part 29 on the diagram in the link below.

Now other than that if both parts check good, whether the water is heating or not, you need to replace the timer because it's not advancing.
