Question about Bosch SHU9915UC Dishwasher
Welcome to FixYa.
Based on your description I'd say the issue actually with the control...unfortunately.
**B/S/H/ also issued a recall on certain models between 1999 - 2006 depending on the model & serial number, you can check with yours, though many not included here still suffers from the same problem...you'll need the serial number too. Here`s the link if you want to see for yourself **
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 ).
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 wheMy bosch dishwasher will not stop running, plus - 9119d99.jpg..
...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...or takes a long time as I mentioned and eventually display's "1" on units with a display and usually very poor cleaning and obviously no "extra" heat ( aside from the water inlet temp. ) 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 My bosch dishwasher will not stop running, plus - f57273b.jpgcates 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 and I don`t pretend to speak on there 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.

Macmarkus is my hero -- the problem identification and solution were perfect. In case it is helpful to anyone, attached is a photograph of my board before I soldered it.

Macmarkus is correct in his description of the failure of the board.
The OP has responded with the correct concerns concerning the risk of fire.
Owing one of these DW's myself, and being the Engineering type that I am, I have determined the reason for the cause of failure is due to the relay being undersized for the application. So much so that I currently stock a heavier duty series of relays, either for Sale directly to those who want to make the repairs, or I will repair the boards sent to me.

The purpose of the air gap is too prevent back-flow and siphoning, and newer dishwashers (past 20 + years) have back flow preventers built in and looping the drain hose (not a circle, but an upside down u to the top of the cabinet or behind/side of dishwasher) prevents siphoning. Aside form being ugly space wasters the cheap air gaps have a tendency to spit and cough water out.
