Question about Bosch Dishwashers
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,
**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.
**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.
