Hi my Bosch dishwasher isn't draining anymore. I ran a couple of rinse and hold cycles to see what it does, and after rinsing with good pressure, it pauses and then signals end of cycle without draining. It leaves water almost over the door seal level. I think the level sensor works because it doesn't add more water if you cycle it again. If you bail out the water and run it, it will does refill. Looked at the little blue impeller under the cover in the bottom and it turns freely. Any ideas, sticky valve, faulty controls? Thanks in advance.

Re: Bosch SHU9915 Does Not Drain
If I may add and with the indulgence of IB4G2008 and Jaime867..... Have you physically checked the drain, drain filter and drain hose for any blockage, clog, kinks and/or anything out of the ordinary pls?
You can also try running a slightly above pressure hose backwards from the drain and try to see what comes out in the drum.

The dishwasher really shouldn't pass any particles near large enough to clog the drain hose. It sounds more like a mechanical issue. Check the circuit breaker to make sure it's not tripped. See if you can hit a cancel button or something to make it drain. Try to run another cycle. If the computer is stuck or acting funny, trying cutting the power for a while, holding down a stop/reset/cancel button, or running a cycle that you don't usually run. I had this kitchenaid that would randomly refuse the normal wash cycle, but would run fine when you ran rinse only or something, then regular wash and everything would be fine again too. If the line somehow is clogged, there's a good chance it's right where the hose connects to the disposal or drain pipe.
I'm positive of this, but your dishwasher may qualify for a somewhat recent recall. Call bosch to see. If you can get it to drain manually and put into rinse and hold manually, but it won't progress on it's own, then it's the control board. Hope this helps.
Fixed mine very easily... After checking and cleaning the filters by the tub's drain, I checked the air vent atop the sink -- it had a small bit of gunk trapped in the outlet. Cleaned it out, ran a "rinse & hold" cycle and it drained the tub beautifully!
My SHU43C is just over 3 years old. I had a similar problem recently. First, there were a few floods. Then, the Bosch only drained non-stop. Even when I used the Cancel Drain buttons the drain pump would run without stopping. When I tried to run one of the cleaning cycles, no water entered the machine. Corrective: I removed the base plate, and saw that the red plastic floatation device was in the up position. Using a flashlight and a wooden spoon, I lightly toggled the red float stem down. I pushed regular clean cycle and kept toggling with the red float stem until the rinse water started to enter the machine (turning the red stem seems to also actuate a step in the program). Now the dishwasher runs normally. Voila!
Im really not all that familiar with the bosch unit, but a few things i would ck. when you cancel a cycle (it should drain the water) is it humming??? does it sound as if it even trickling into the sink discharge?? do you have a disposer under your sink that this unit drains into, if so remove the clamp and look for possible obstructions right there.Honestly passed this ill have to defer to someone else sorry and good luck
