sadly enough, same problem. looks as though micro processor is defective.
SOURCE: Bosch SHU43C
My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!

Hello,
Welcome to FixYa.
Based on your description I'd say the issue is with the control...unfortunately.
The number"1" being displayed ( on models with the display like yours ) is actually an error code indicating a fault in the heating process.
Bosch has had a history of this exact problem I'm about to lay out for you and this is the first thing I'd be looking for if called out to service the unit with the symptoms you've described.
**B/S/H/ also issued a recall on certain models between 1999 - 2006 depending on the serial number so you may want to contact Bosch to inquire if yours is affected.**
http://microsites.boschappliances.com/safetyrecall/dishwasher/
or
Bosch dishwasher hot-line 1-800-856-9226 1-800-856-9226
Before calling, have the model and serial numbers on hand. A live operator can be reached at the hot-line 24/hrs day.
Those not affected by the recall still can be a problem but easily fixed. As I've alluded to the issue is likely within the electronic timer/control, specifically the heater relay solder joint. ( a faulty flow switch, ntc or heater can also cause this, but not very probable ).
My first suggestion would be calling in an authorized bosch service tech. if that is an option for you and your budget however, If you feel capable of checking this on your own, there`s a way to visually inspect the control yourself.
It will require you to remove the control from the unit and then remove the control from it`s plastic housing and look for a burnt solder contact on the printed circuit board. 
The culprit will 99% of the times be one of the pins from the heater relay,
**Your control WILL differ in appearance, however the issue, the service and all the same info applies...except the part number. Yours will be # 431692**
**Flip this over and inspect the solder joints, it will be obvious when you see it...the cover for your models control comes apart in a similar manner**
This is where and what to look for, except I`ve re-soldered this one already...
...hence the unit sit`s and takes longer & longer to finish because it can`t heat to advance or unless the 2 buttons for "cancel" are pressed, other-times it will eventually stop or display "1".
You can also run the unit through a regular or econo cycle ...any cycle with the exception of rinse & hold, and with the door panel removed place an ammeter on the gray/black wire it should draw 11 amps during the wash cycle...after it fills and the flow switch indicates it has adequate water to engage the heater.
i.e.
**My Opinion - if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...but it has to be done well...or it will not last, although Bosch recommend`s replacing the control ( # 431692 @ approx. $150 - $250USD...$167.99 at "searspartsdirect.com" ) and I don`t pretend to speak on their behalf nor do I profess to know better. This is just my experience (it work`s) and my opinion (why buy new if one can repair ?)**
**Please disconnect the power or turn off the breaker before attempting any service to the dishwasher.**
If you do not feel comfortable attempting this service, call a local pro, preferably one familiar with Bosch/Thermador/Gaggenau/Siemens, to service your machine.
Hope this answer`s your question, let me know if I can assist you further.
Thank`s for visiting "FixYa" for your repair inquiries. Please take a moment and rate this solution to it's helpfulness.

To begin the test program, press both the SCRUB WASH and DELICATE/ECONO wash program buttons at the same time
as you turn the unit on by pressing the ON/OFF button. Initially, the control unit version number will appear in the display
(e.g./ 20 = version 20, 21 = version 21, etc.).
When the wash program buttons are released, the LED's above them will begin flashing. To end the test program or test cycle, press the ON/OFF button.
To check the wash program LED, press its corresponding button.
To check the Cycle Countdown display, Refill Rinse Agent LED and REGULAR WASH button LED, press the REGULAR WASH button (press the DELAY START button to test the
Cycle Countdown display alone).
The Cycle Countdown display should show "88" when the DELAY START button is pressed and "8h" when the REGULAR WASH button is pressed.
To start the test cycle, press both the SCRUB WASH and DELICATE/ECONO buttons a second time.
When the test cycle has completed, the Cycle Countdown display will indicate a fault using the codes below. If a combination of faults exists, the code numbers will be added together, (e.g./ 6 = faults 2 + 4).
0 = No faults
1 = Aqua Sensor ("Sensotronic") fault
2 = Heating fault
4 = Filling fault
8 = NTC (temperature sensor) fault
email me at [email protected] and I can send you via a "pdf" of the diagnostic/repair manual for your specific Bosch...provided it is indeed a SHU5316 unit.
I`ll watch for your reply. Good luck.
Regards,
Macmarkus :)
