When I start a new cycle, I first hear the pump run to empty out all remaining water, and after that I hear the motor run for the regular washing cycle, but there is no water in the dishwasher. After a few minutes, the cycle stops, and the washer claims the dishes are 'clean'. When I try starting a new cycle over and over again, about one in 20 times, the cycle will run normally with water. But then the next time, the problem starts all over again. Once a cycle starts correctly, everything works fine, including the rinsing.
Possibly an intermittent water valve problem. If not that, then a control board issue

It sounds like your water inlet valve or the control mechanisms faulty. since it works periodically my bet on the later inlet valve. Especially if your washer has electronic control.

sadly enough, same problem. looks as though micro processor is defective.

ok first of all there is a drain pump and wash motor pump. which one is running?Then tell me what kind of buttons u have.Are the touch buttons or plastic buttons that move

hi there your dishwasher has gone into flood protection mode ie. water has leaked into the base and activated the float switch.
to try and locate the leak tip your d/w back to drain the water from the base then remove both side panels and start a program to see if you can see where the water is leaking from, being careful not to touch anything while the d/w is running as live parts are exposed
hope this is of some help

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.

Hello,
Welcome to FixYa.
Based on your description I'd say the issue actually is with the control...unfortunately. This is commonly associated with a heating fault as you suspected, hence the odor and poor cleaning on Bosch built dishwashers ( various models including Bosch, Thermador, Siemens, Gaggenau, and Neff ).
Since 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 ). These are the steps you'll need to follow to resolve it or at least investigate.
If you feel capable of checking this on your own, there`s a way to visually inspect the control yourself...it really isn't very complicated.
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,
**Flip this over and inspect the solder joints, it will be obvious when you see it.**
This ones new, but it's where to look...
...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...this can also manifest as a long cycle time as I mentioned and eventually display's "1" on units with a display and usually very poor cleaning, no heating ( don't be fooled by the homes inlet hot water temperature ) as a result.
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. ( this may differ from your specific model, but the same rules apply )

Update: To be more clear, when I start a cycle, the drain pump will first run for about 15 seconds, and then stop. A few seconds later, the wash pump starts running, without any water. After about a minute, the wash pump stops, and the cycle stops. The machine has plastic buttons that move, on top of the door.
From the brief description you have given, I suspect that there is a water supply problem. Check the filter between the inlet water hose and the water inlet valve, there is usually a filter in that area and may be blocked. if there is no filter, or the filter is clear, it will be necessary to check that the water valve itself, if there is a fault with the valve, it will need replacing. I hope this helps?
