hi there sounds like the wash pump has become ceased, isolate unit from power and remove left hand side panel the wash pump will will now be visible, gentle turn the induction cooling fan at the rear of the motor being careful not to damage the field windings then restart the prog.

heres a screen on the inlet to the water solinoid that plugs up with calcium alot of the time. shut off the water and take the bottom panel off the unit and you will see where the solinoid is. take off the water and then take the solinoid out and apart to clean. reassemble and you will be good to go.

I would check the bottom of the dishwasher to see if there are any bones, old food built up as some of these collection systems have a small disposer built into them.
If you find any food, it's probably that.
Also, you can make sure that the drain line is the proper length and high enough as this is a common problem. Do a good search on proper drain height for dishwasher.
You may run an empty load of dishes with a cup of bleach added to eliminate the odor as well. Bleach will kill any bacteria causing the smell. More than likely the drain hose wasn't installed correctly.

Hello and welcome to Fixya. The assesment of the control is likely accurate. Siemen is made by B/S/H/ ( bosch/ thermador/ siemen/ gaggenau) and there is plenty of president for this issue. Likely if you select just a rinse cycle it will complete fine since the rinse cycle doesn't call for heat from the element/control. sooo... Based on your description I'd say the issue IS indeed with the control. As I said B/S/H/ 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. ( unless you requested a resolder option...see below re: my opinion on this ) I digress, As I've alluded to the issue is 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/siemen servicer if that is an option for you and your budget however, If you cannot afford that option or simply feel you want to attempt and are 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. This will be one of the pins from the heater relay, hence the unit sit`s and takes forever to finish because it can`t heat to advance or unless the 2 buttons for "cancel" are pressed. **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...half assed 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 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/Siemen/Gaggenau, 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. Good luck. macmarkus :)
