Question about Bosch 24 in. SGS4072 Free-standing Dishwasher
Hi, the dishwasher just rumbles on and won't porpgress. If I manually progress the dial it moves on and keeps making a washing noise, but then it hangs up again. If I keep rotating the dial manually to the end it then won't turn off... just keeps rumbling away. Any clues?

This sounds like a thermal stop as well. The unit wants to get up to a final rinse tempurature but can't reach it so just keeps going. If you have an amp probe you can check to see if the heater is coming on in the final rinse. If it is not, could be the thermistor of even the heater.

Introduction: This may work for your problem, but only if you're finding that you cannot get further water to flow into your machine. If your machine fills, OK, then this ISN'T a solution to your problem.
I have a Bosch SHV. My sink drain backed up, and the water accumulating in the sink then migrated to the dishwasher, through the drain pipe, causing the dishwasher to fill up and, it turned out, overflow a little. When I turned on the dishwasher, the water drained, but no new, clean water came through the hot water pipe. The drain just kept running, but nothing else happened.
Here's what happened. Under the main chamber of the dishwasher, by three inches or more, is a white plastic tray. It sits almost at the floor, and it may not be obvious that it's a tray capable of holding water. The overflow water spilled into that tray, which in turn caused a float in the far left side of the tray to lift (the way a toilet float lifts when the water fills in a toilet tank) and shut off the water intake valve (like the toilet float shuts off the toilet water flow). So long as that valve is closed, your machine will not run.
STOP: disconnect power supply at this point for safety.
To see the white plastic tray and thereby fix the problem, you'll need to take off the BLACK TOE-KICK (attached on my unit by two star-head screws at its bottom) and, possibly , the OUTER PANEL OF THE DISHWASHER DOOR (in my case, a custom wood panel (attached by a few screws through the inner side of the door, two screws that are accessed by popping off little--smaller than a dime size--covers on the sides of the doors, and then the door panel lifts up and out). (I took the outer panel off, but I can't remember if I would have had to reach into the white tray without doing so.)
Once you do that, you can see the white plastic tray. It doesn't come out--at least not without removing the entire machine--so try this. You can take your fingers and feel over and into the tray. You'll probably feel the water--I did. Look at the far left of the tray with a flashlight. Back there you'll see a flat, round, 3-inch diameter piece of white plastic sitting at the bottom of the tray. To its center is a generally U-shaped lever looking device, which, at its far left end, is connected to a red stick pointing up into the machine. When water goes into the tray, the float rises, causing the U-shaped lever to rise, causing the red stick to raise, which (though I couldn't see it) causes an electrical signal to run to, and shut, the valve for your water intake.
I took paper towels, and then a narrowly cut sponge, to sop up the water in the tray. I then took my shop vac and, using it as a blower, blew what little water was left right out. You might be able to use a hair dryer, but first sop out what you can or it'll take forever. Once you've done that, put everything back together and plug your dishwasher back in. My buttons are at the top panel. To reset, hold down the two buttons marked for clear drain for three seconds and release. You should be able to start up then. It took 15 seconds before the water started to run, but it did and the machine works fine again.
Interesting note: The valve that stopped the water from flowing in automatically opened once I got the water out of the tray. You don't need to reset the valve.

We have had the same problem, except the water was not getting hot either. After a ton of research there was an issue that kept popping up. There was a massive recall on many of the model and serial #s. According to the recall there was a fire risk from the control board, the brains for the machine, that sits behind the digital display. For those not "at risk" but with the water not heating and the run time increasing, the problem can still be with the control board. I removed the control board and found a burned out connection with one of the controls. I soldered it and put the machine back together. The run time has returned to much closer (down to 128 from 184) than before the fix, but still is not back down to the original 108 minutes. I've priced a new control board--about $120.
This happened right after the warranty ran out. Imagine that.
