Question about Bosch 23 in. SHU 8805 Built-in Dishwasher
At the end of a cycle, the dishwasher doesn't drain and there is a bunch of water at the bottom. I have taken apart the filters and there isn't anything that i can reach at. Any ideas on a fix?
This is generally because of a stuck diverter solenoid. The water goes to the pump and then is either sent to the wash arms or the drain. Also, check the drain.

I had this same problem and in addition as it ran water dripped out the bottom while the dishwasher was running just before the tap light came out. Check the outlet hose is not blocked. Ours was blocked at the T junction where it met the sink outlet. Once the blockage was cleared we hit another problem - the pump kept trying to drain - even when the door was open. Found an excellent solution to that on this site. It had occured as the previous problem had casued the flood switch to be triggered. We had to tile the sihwasher back 45 degrees to fix it. Now its workig fine again.

Kindly check for the following :
Check for hose kinks or food plugging drain hose. Start at the drain port exit.
Check the check valve and drain hose for debris.
Check pump motor for reversing during the pump out make sure the dishwasher is pausing between the wash and drain cycles letting the pump/motor reverse for the drain cycle.
Check pump motor assembly for a drain solenoid, during the pump out make sure the solenoid makes that distinctive "clunk" noise
If you have recently installed a new garbage disposal, check knock-out plug at connection.
Check pump impeller for damage.
Check that the water inlet valve isn't seeping fresh water into the dishwasher when off.
Please contact for any further clarifications.
A Fixya Rating would be appreciated if.

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.
