SOURCE: Replacing a drain hose
If you remove the steel left side panel you can see that the drain hose only extends a short way into the machine. Where the hose enters the pan is a white clip that has a small square hole this clip can either be removed by pushing on it from the inside or prying the small square hole with a screwdriver. the drain hose is held in place by a black triangular clip on the plastic drain loop simply pull the clip off and slide the drain hose down then pull it out from the back of the machine.

fault is that there is a leak. the tray at base of dishwasher is full of water which operates a float and turns on drain pump. tilt over 45deg and water will run out and then it will work or remove bottom front panel and mop out (better). then find leak

There are no adjustments for cycle timing. What does affect timing is temperature of the water coming into the DW. The hotter your supply water, the shorter the time to cycle, BUT if your water is too hot, the cycle time may become too short to light the NSF 'Sanitize' indicator. But since the cycle is taking so long, this is an indication that the DW's water heater is not heating the water hot enough to advance the countdown timer in a timely manner. The control logic is waiting for the temp to come up to an appropriate level to ensure adequate washing, rinsing or drying times. Likely your display is showing '1' for a long time as a symptom of this problem, as well.
This link http://www.applianceaid.com/boschDW.html has procedures to run self-tests on various Bosch models. I suspect that you can confirm a 'heater fault' on your unit by running the self-test.
This 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. If you have a Torx driver, soldering iron & bit of solder, you can effect a repair yourself in about an hour. Otherwise, a replacement control board is required.
- If you'd like to attempt replacing the control board yourself, refer to this link for part & DIY information. http://www.appliancejournal.com/appliance-parts/bosch-appliance-parts/bosch-dishwasher-control-module-266746-37/
