Question about Dishwashers
We bought a Bosch diswasher and it stopped pumping water after 18 months. Does anyone know if this is a known problem? I now have to pay for the labor on a very expensive boat anchor.
My Bosch dishwasher had the same problem. After checking the over flow pan I removed the inlet hose to check water flow. There was none. I checked my cut off valve...open...I had water at the kitchen facet...scratch my head...I looked closer at the Bosch supplied braided water hose. It is directional (label indicating which end to hook to supply)....closer inspection reveals maybe there is a back flow valve in that side of the braided hose. Disconnect, blow air through...air passes freely...reconnect and bingo water flow at the dishwasher. In line back flow valve...can you imagine what a repair man would have charged for that?

SOURCE: Bosch Diswasher not draining
Soyben, you need to check to see if either the drain hose or syphon break at the sink is clogged. The drain motor on this model is not a bilge pump that will remove water from the base. Therefore Im leaning on a restriction somewhere. Other than that you may have to check for debris in the drain sump. Check these areas out first...Catriver...post back

Introduction: This may work for your problem, but only if you're finding that you cannot get further water to flow into your machine. If your machine fills, OK, then this ISN'T a solution to your problem.
I have a Bosch SHV. My sink drain backed up, and the water accumulating in the sink then migrated to the dishwasher, through the drain pipe, causing the dishwasher to fill up and, it turned out, overflow a little. When I turned on the dishwasher, the water drained, but no new, clean water came through the hot water pipe. The drain just kept running, but nothing else happened.
Here's what happened. Under the main chamber of the dishwasher, by three inches or more, is a white plastic tray. It sits almost at the floor, and it may not be obvious that it's a tray capable of holding water. The overflow water spilled into that tray, which in turn caused a float in the far left side of the tray to lift (the way a toilet float lifts when the water fills in a toilet tank) and shut off the water intake valve (like the toilet float shuts off the toilet water flow). So long as that valve is closed, your machine will not run.
STOP: disconnect power supply at this point for safety.
To see the white plastic tray and thereby fix the problem, you'll need to take off the BLACK TOE-KICK (attached on my unit by two star-head screws at its bottom) and, possibly , the OUTER PANEL OF THE DISHWASHER DOOR (in my case, a custom wood panel (attached by a few screws through the inner side of the door, two screws that are accessed by popping off little--smaller than a dime size--covers on the sides of the doors, and then the door panel lifts up and out). (I took the outer panel off, but I can't remember if I would have had to reach into the white tray without doing so.)
Once you do that, you can see the white plastic tray. It doesn't come out--at least not without removing the entire machine--so try this. You can take your fingers and feel over and into the tray. You'll probably feel the water--I did. Look at the far left of the tray with a flashlight. Back there you'll see a flat, round, 3-inch diameter piece of white plastic sitting at the bottom of the tray. To its center is a generally U-shaped lever looking device, which, at its far left end, is connected to a red stick pointing up into the machine. When water goes into the tray, the float rises, causing the U-shaped lever to rise, causing the red stick to raise, which (though I couldn't see it) causes an electrical signal to run to, and shut, the valve for your water intake.
I took paper towels, and then a narrowly cut sponge, to sop up the water in the tray. I then took my shop vac and, using it as a blower, blew what little water was left right out. You might be able to use a hair dryer, but first sop out what you can or it'll take forever. Once you've done that, put everything back together and plug your dishwasher back in. My buttons are at the top panel. To reset, hold down the two buttons marked for clear drain for three seconds and release. You should be able to start up then. It took 15 seconds before the water started to run, but it did and the machine works fine again.
Interesting note: The valve that stopped the water from flowing in automatically opened once I got the water out of the tray. You don't need to reset the valve.

Hi, it sound's like the wash motor is either seized or just stuck, let's hope it's the later. Bosch had issued a service tip about this problem several years ago titled "Loosening Frozen Impellers" strange choice of word's considering nothing is froze..at least you'd hope lol. I have a copy of it at home and I can likely post it later, ( I'm on my iphone presently ) but essentially what it say's is this...Remove the pump fitler ( inside the tub under the bottom rack ) locate the hole to your right down in the sump well, you should be able to see it with a flashlight or well lit area. Once you've located this hole ( it's providing access to the wash impeller without pulling the unit from the cabinet ) reach in with a 8mm nut driver and locate the end of the impeller and turn it clock-wise until it feel's to turn freely. Give it a test perhaps in a rinse cycle before you put all the filter and screen back together. It should be fine unless the motor is seized, we'll cross that bridge when we get to it, try the repair tip for now. Let me know how that help's and/or if you need further assistance. Thank's for visitng "fixya" for you repair tip's. If this is indeed helpful please rate the solution accordingly, if not, again please let me know. Thanks again and good luck. Macmarkus :)
