SHE3AR55UC/07. How can I select a short wash?

SOURCE: Bosch WFF 2001 wasing machine

check the water inlet valve where the hoses connect shut water off and take the hot hose off look in the valve there is a small screen that maybe clogged if not report back and we can go in deeper

SOURCE: Washing cycle starts and takes hours even for short cycle.

Try checking for good water supply.
Pull out detergent tray and check for good water supply during filling.
if poor filling-
Try checking the hoses.
Turn taps off, disconnect from machine, place hose end in sink, turn tap on and check for good water flow.
if the hose has a red indicator in the side of the hose (end which is fitted to the tap) - Red indicator is a failed hose.(for models with Water Stop hose type "B")

Try this link, http://www.applianceaid.com/boschDW.html for procedures for running self-tests on various Bosch models using the front door switches. Find your model and read and follow the procedure.
This remaining at '1' problem invariably relates to a 'heater fault' which has usually been traced to an open solder joint on the control board located behind the switches/indicator lights on front door. See pic here of open solder joint http://www.flickr.com/photos/zenzoidman/145089572/ In most cases, the heating element has not been at fault.
I got mine going again by resoldering the joint and saved ~$300 in parts & labour. If this is beyond your skill set, then replace the control board assembly, 266746, which is used on multiple Bosch models. See this page for more information if you want to try to DIY. http://www.appliancejournal.com/appliance-parts/bosch-appliance-parts/bosch-dishwasher-control-module-266746-37/

If this is still beyond your skill set, then call a tech & supply the Bosch model, serial number, and the results of the self-tests.

Your "cycle selection switch" is probably the timer motor. If tapping it lightlly gets it going again it will probably need replaced. It could be a loose connection but I would need to know the model number to tell how to get into the inside of the control panel to look. If you do get adventurous, be sure to unplug the washer before taking the panel apart.

SOURCE: my bosch 5316 runs for over 2 hours. any ideas?

This is typically caused by a heater/heating fault, but not necessarily the heater. It is much more likely poor solder on the control for the heater relay. If you are proficient with electronics, or willing to dig deeper it is a repairable solder contact...usually, but you must be able to solder. If not the replacement part is a BT-266746. Having said that, I'd think you'd be best served by me if I suggested you call a tech in your area, preferably a bosch (b/s/h) authorized servicer. Hope this helps, give me some feedback so I know if we can help further. Good luck
