The pressure chamber or hose (pressure chamber to sump) may be blocked and the microswitch is being activated because the water is not entering the tank quick enough. Isolate from electric, remove lid and left panel (looking from the front). There is a plastic chamber bottom right of left side with two microswitches, either this is blocked or the hose that runs from it to the right and along the back of the kick panel and into the sump. Clear either or both (make sure all hoses are pushed true when repositioning).

Hello, welcome to Fixya. I know this post is a few days old, but in the event you haven't found a solution yet I'll throw my 2 cents into it. I suspect the "1" is actually an error code and not coincidentally the reason it doesn't dry. Here`s the most likely reason why it has detected the error... Even if your home water supply appears hot, it's not hot enough and must be heated by the dishwasher to insure a proper clean and dry, hence most if not all manufacturer`s do this. When it comes to your Bosch dishwasher the problem likely lye`s 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 ). To repair your unit 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. This will be one of the pins from the heater relay, hence the unit sit`s and display`s the error "1" telling you it can`t heat the water. ( I can send you documentation directly from B/S/H/ confirming and explaining this if you'd like to post your email address ). **Further to this, if you or someone you know is proficient at soldering, a lot of times it can be remedied by simply repairing the solder...although Bosch recommend`s replacing the control 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 before attempting any service to the dishwasher** Installing a new control will certainly remedy the problem as well. But when it is priced at about $170.00 I am more likely to offer someone an alternative to buying new, hence my first reaction to mention this repair tidbit. The control is available at most brick & mortar appliance parts stores or on-line at vendors such as "repairclinic.com", "apwagner.com", "searspartsdirect.com" etc. part number is based on your specific model number so you`ll need to provide that. Hope this answer`s your question's, 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 you and leave a testimony if you're satisfied. Good luck. macmarkus :)

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 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.**
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 )
**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. Bosch recommend`s replacing the control 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.

SOURCE: Electronic controls don't count down properly
you have to replaced the main control resoldering wont fix it because the relay itself has gone bad replacing the board will solve the problem

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.
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,
**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
Have you tried canceling the cycle? To cancel, turn the on/off switch to on, then press and hold for three seconds the two buttons labeled "Cancel Drain". Keep the door closed for the next minute so that the dishwasher can complete the cycle. During this time the pump will remove any water from the washer. Also you will notice that Bosch dishwashers always leave a little water in the system to keep the seals from drying out and going bad.
Hope this helps
