Purchased a used bosch shu5315 06, which we were assured worked fine. ha! Have replaced the control board in it and dishwasher now will start wash cycle, fill with water, drain water, then fill with it again. At this point it stops working while the timer continues to count down. We have to use the clear function to get it to drain the water out. Any ideas what we should check next? My husband is fairly handy but we do not really know exactly how the dishwasher is supposed to work through it's cycles when it's running a normal cycle. Thanks for any help you can give us!

Long running time on a Bosch dishwasher is almost always a blown solder joint at the heater relay on the control board. You can resolder the joint, replace the relay or replace the control. Control board part number is 00266746.
I would call Bosch with you.re model and serial number, they have had a recall on your model for the control board and that sounds like it may be your problem, if it is under recall Bosch will send someone out at no charge to install a new board (800) 856-9226
BOSCH IS HAVING A PROBLEM RIGHT NOW WITH SEVERAL OF THERE CONTROL BOARDS...as a matter of fact just out today on a bosch shu33 model dishwasher and control was bad and was told by a local supplier there is a recall on these control boards.... based on you explaination it sounds like the control is bad and will need replaced... good luck to you..
break out the honey do list . ah ha ha ha ha ha the food debris from washing has your drain line stopped up. start with the p-trap under the sink, and flush out the gunk . then if needed maybe a backflush with the waterhose thru the drain tube that comes from the washer to loosen some food particles. use low pressure so you dont have to mop up too. thats usually the problem
My Bosch dishwasher did the same thing. When the wash cycle starts, the dishwasher fills with water and then the heater is supposed to turn on to heat the water. If the water does not heat, then it will display 2H continuously. The heating element may be bad, but a more likely cause is with the control module. Bosch has a problem with the control module printed circuit (pc) board that powers the heater on many models. The solution requires some technical expertise and soldering skills. The details are explained in the document "Bosch dishwasher troubleshooting tips" on page 11. Download here Bosch recommends re-soldering the connection, which is a temporary fix. The problem is that the copper conductor (called a trace) on the circuit board is not wide enough to handle the current required for the heating element, and as a result the copper trace overheats, causing the solder to melt on the relay connection. The best solution is to remove the control module PC board and solder a short length of copper wire between the pins to prevent the overheating problem, as shown in the attached photo (magnified portion of PC board). I did this on my dishwasher and it has been trouble-free for over 3 years.
The control board on these units is prone to a cold solder joint cracking. I have read that Bosch recommends replacement and will supply the board, not covering labor. I repaired mine prior and have done one for a friend as well. Has lasted several years and counting The symptom is constant cycling without ticking down the last few minutes
I had the same problem and just today replaced the control board module. Purchased the control module online and installed in myself. Was not that difficult. undo the screws (torx screw driver needed) unhook the connections to the board and label all. Pull the board out and open, found burned connectors. Now works like a dream.
Make sure you visit the Bosch dishwasher recall website as this model is under the recall with a faulty controller which may cause a fire! Check your model under http://microsites.boschappliances.com/safetyrecall/dishwasher/
then call 800.856.9226 to setup a recall repair appointment. We just found out about this recall and was never notified by Bosch even though we registered our unit after we purchased it...talk about poor customer service! Hope this helps!
