Question about Bosch 24 in. SHU53 Built-in Dishwasher
SOURCE: Bosch dishwasher SHU9922UC
Sounds like you already know how to fix it. The inlet valve is only held closed by water pressure...if you have low water pressure it could be causing this. Its more likely just a bad fill valve though. The water inlet valve is accessed by removinf the lower kickplate and the sheild behind that. Then all you have to do is remove the water line from the valve, remove the 2 screws holding it and pull it out far enough to disconnect the 2(possibly 3) wires and the fill hose. Make sure to mark where your wires go, if you hook it up wrong it could continue to fill and overflow. Hope this helps!

SOURCE: No water in dishwasher
I have a SHU9922UC and the control panel has just died for the third time in 10 months. Its symptom is a dishwasher that runs and runs but never fills. I was told that this is an issue with this model. When they pull the control panel you can see a "burnt" area on the board. at $150 a repair, I'm getting a new dishwasher. It works great until the control panel wigs out.

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.

The flood switch is tripped. This is located under the unit. Unplug or flip the breaker to the dishwasher, take off the black kick plate under the door, 2 screws, and you will see the white plastic "pan". The flood switch is located where you can't really see it but it is on the left hand side wall and is made of styrofoam. The best thing to do is to put some rags in the pan, this is not easy because there is little room to put them, and soak-up the water that has filled the pan. Eventually you will get enough water out that the float will deactivate the switch. What you hear "running" when you turn it on is actually the drain pump, it get activated when the flood switch is tripped.

Welcome to FixYa.
Based on your description "dishwasher when turned on sounds like drain pump is running but water will not enter dishwasher" , it sounds like the emergency overfill switch has been actuated. Here`s what to do and what to look for.
**Turn off the breaker/power at your homes service panel...safety first of course**
Remove the the bottom panel, referred to as a toe panel or kick-plate, essentially the lower service panel shown here...
When you remove the outer toe panel, there will be another small panel which is non finished steel, I find removing that allows much easier access as well.
This panel can be somewhat more difficult as it secures the plastic channeling for the wires but if you observe closely you`ll see it does "snap" out of place...carefully.
Once the panel has been removed check for any obvious signs of water in the base ( the unit has a plastic overfill basin with a float which will actuate an emergency overfill cycle, hence the drain pump runs & runs )
If you don`t see any water in this area, direct your attention to the left in this basin/bottom ( from the front to be sure ) and you should see a device which will resemble a "stir stick" you`d use for coffee etc. it will be a red in color stick.
With the aid of a wooden spoon, long screwdriver, or if you can manage to reach by hand, lift it up and down gently and listen for a "click".
If there is no sign of water and you can here the "click" when lifting up and down the float actuater ( red stick ) then turn the machine back on and give it a try before reassembling the toe panel so you can observe for any possible leaks.
Let me know what you find. This is the most likely cause of the symptom you are describing so we can move forward if this doesn`t resolve the issue.
Thanks for choosing FixYa. Good luck.
