Commonly this is result of low water pressure or hose height/length
As long as the water is below the heating element and the dishes are getting clean its actually normal. Sometimes the pressure or hose length/height meets specs but will not always drain all water.
But as long as it is below the heating element this is normal
I am sure.

If there is any blockage in your diposal, water will comes up to the sink, since it happened to me. As soon I installed the air gap then it fixed the problem. No air gap, water flowing is slowing down conflicting with timed draining causing this problem. Let's think of this, if you fill up water in a 1/2 galon milk container, and you try to emty it. If you pull down straightly , it will be slow compared to pull it at an agle to let air going into the opening. The air vent helps water flow better meeting the timed draining.

SOURCE: Bosh dishwasher SHU43C05UC won't
Welcome to FixYa.
Based on your description " won\'t finish the cycle. won\'t drain and keeps running for ever when gets to 1 min left.Hoses checked and not clogged. I was able to drain the water by doing the test run and punching the rinse and hold button" I'd say the issue is most likely with the control...unfortunately. The "1" being displayed is actually an error code associated with a heating fault.
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 model & serial number, and it does apply to yours....based on just the model number, but check the serial number. It applies to serial numbers betweenFD7905 - FD8505 The issue was directly related to the heating circuit (specifically the heat relay on the control) 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 ).
My first suggestion would be contacting Bosch re: the recall or 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 & 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.
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 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. I would recommend you contact Bosch regarding this recall, perhaps the repair will be free...but I don't speak for them.

Hello, welcome to FixYa.
Based on your post I understand you have a Bosch SHU3307UC dishwasher, correct ? Firther to this you.ve stated "slowly fills the bottom between cycles, even with little or no activity at the sink"
It sounds to me like the fill valve is at fault unfortunately. This is a very common problem for Bosch dishwashers of that era.
A faulty fill valve...sticking in the "open" position either due to the plunger in the coil getting stuck or sediment inside the valve body impeding it from closing correctly...Either way you're safer to change it with the history of these valves failing.
This is what to look for...
As long as your model is indeed a Bosch, this info below will be accurate.
Original part is # 425458. It usually retails for about $20 - $30USD at places such as "searspartsdirect.com" "repairclinic.com" to name a couple, if needed. They may be available at your local brick & mortar parts depot/vendors.
**Before attempting to repair the unit please turn off the power and the water supply to the dishwasher...safety first**
If you remove the lower kick plate/toe panel, you will see the inlet valve to your left...
Replacing it or to check for debris in the filter/screen at the inlet is pretty straight forward. Here`s how...
1) undo the water line. ( here you can visually inspect the screen in the valve...if nothing noted, you'll likely need to replace it as follows )
2) Remove the two #20 torx screws fastening it in place.
3) the feed tube to the machine at the back of the valve and swap it with the new one.
Once the new one is in or it's all clear you should be good to go.
Let me know if you need any further assistance. Thanks for choosing FixYa and good luck.
