just had the same problem with dish washer not draining..so before buying a new pump like i did firstly remove the old pump and give it a good check over a new pump cost me £32.90 to do this follow these instructions as i made a few errors but got there in the end.
unplug dishwasher as your gonna get wet...
turn washer onto its back
remove the 2 bronze coloured screws on the side plastic facia ( only 2 screws there 1 each side)
now with abit of force remove the front bottom plastic (it does come off believe me)
after your struggle, remove metal facia (behind the plastic bit in your hands) two screws to undo
carefull not to damage any of the wiring attatched to the metal facia
unclip the wireing remembering how it goes
there are two screws attaching the bottom plastic casing to the pump undo these and again pull down on this to gain access to the outlet pump (not to hard)
twist off the pump no screwing needed the wiring to the pump is two spade connectors the other wires you see are just clipped to the pump housing.
inspect if no damage then maybe a pump is needed, if obstruction then clear and twist back on connect wires
follow the reverse of removal
should take about an hour

I believe that is a no drain error. You can check to see if there are objects in the sump area like glass and food. If the water from the dishwasher can not drain into the air gap the dishwasher will be unable to drain. The sump is the area where your filter sits. You might have a bad pump or a blockage somewhere.
Hi, welcome to Fixya.
By the description you've provided, 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.
Essentially what it say's is this...Remove the pump filter ( 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 so it's a 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 visiting "fixya" for you repair tip's. If this is indeed helpful please rate the solution accordingly, if not let me know.
Thanks again and good luck.
Even if the pump is not working, then so long as there is no water in the washer, it should spin
If it does not, then I would suspect the motor brushes are worn out.
You need to remove the motor to check the brushes, if they are less than 2 or 3 mm long then they need replacing.
I do not think the washer you found is off the pump,more likely out of someones pocket.
Hope this helps with your problem.
It is possible if you have broken a glass recently that the piece of glass has made its way to the drain pump impeller. You need to remove bottom basket. Remove the filter strainer clamp by rotating CCW. There may be another round filter under the strainer (depending on model). Then with a torque screwdriver remove one screw which holds the plastic pump cover on. Remove the pump cover and pay close attention to the pump impeller. Does it rotate by finger movement? If not it could be jamed with a piece of broken glass. You must remove any obstruction to allow the impeller to turn. I usually force a paper towel piece (half piece while rotating the impeller by finger to allow the paper towel to bring up any obstruction below the impeller) Reassemble the cover and filters carefully and make sure the final strainer clamp aligns correctly with its marks. This insures nothing will make its way to the impeller in future.
If you remove the filter in the sump area underneath the lower dish rack (removing the screws to do so) you may find debris blocking/jaming the impeller area. Be very careful of almist invisible broken glass. Inspect the impeller to make sure it is properly in place and not damaged.
Confirm that the spray arms are not pluged.
If problems continue and the impeller is in good shape, the pump motor may be failing. Please get back to me if problems persist but also include the Make and Model number whe nyou do.
i recently had the same problem of a loud screeching noise. my unit
was installed new in 1999 and has worked well up to this point.
when i disassembled the tub water filter i found the filter was heavily
clogged (it is supposed to be self cleaning), and i also found glass
shards from a broken wine glass. i further disassembled the plastic
housing under the filter ( held in place by three torx drive screws )
which covers the pump impeller and holds the lower spray arm. while i
did not find any blockage in the pump area, and no abnormal sound when
i turned the impeller by hand, i did find that one of the pump impeller
vanes has a small chip which probably makes the impeller unbalanced
resulting in more than normal vibration. i cleaned the water filter
and reassembled the parts and the original screeching noise is now gone.
try removing pump some models can be serviced fron inside well of machine glass can stop the pump from turning
clean out water and remove filters find a screw in base of well remove and remove pump housing check with torch to see if any obstuctions there if not see if the impellor moves around when turned and make shure that the pump is not worn out
