Question about Bosch SHU9926UC Built-in Dishwasher
Dishwasher heats up runs threw cycle but will not drain. All drain hoses are clear. Pulled drain motor and it runs when energized. Could this be a circuit board problem? Other solutions?
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/
- Else, place a service call to the tech of your choice.

This is such an easy repair, you'll be shocked and surprised! The reason this is happening is that the computer or timer has detected a "flood" condition and has permanently energized the drain pump to clear the "flood".
What you'll need to fix it...
1.) Shop-Vac (for vacuuming water) with a crevice tool (like one of these)
2.) T20 Torx bit with a driver. Torx sizing here. (You can get a set at Home Depot or Lowes)
All you gotta do now is get down on the floor and remove the kick panel. Then remove the screws holding the water valve and lift it up out of its' plastic holding. Now your shop-vac w/ crevice tool can be used. Stick the crevice tool in there (about 10") and vacuum up all the water that's been trapped in the basin. (you may need a flashlight to see what's going on back in there...) After the water is gone, your DW will work fine.
Here's how it works... About 10" behind the inlet valve is a "float" made of styrofoam. When water gets into the basin, the float rises and eventually trips a "flood condition" switch. This switch shuts the unit down and will only allow the drain pump to operate. So what you want to do is get the water out of the basin.
There may be a reason for the basin flooding, though. Suds (caused by too much (or the wrong) detergent), an actual water leak from the valve, etc... So after you get the water out of there and the unit is working again, you may want to monitor it (like, only run it when someone is home) for a while just to make sure that a real flood does not occur.
Hope this helps.
