I have a Blanko BDW126X that would do a PRE-WASH (8min) cycle with no problems but when I tried a NORMAL (250 min) or a RAPID (90 min)cycle there was a very loud buzzing noise after about 2 minutes of operating most of the technicians on this forum point to a fault pump.
I do not know if this will work for you but it certainly fixed my problem, try this...
I ran 7 PRE-WASH cycles one after the other allowing the machine to 100% complete the cycle, then I tried a NORMAL wash cycle. The blockage in the pump was cleared and my dishwasher again works brilliantly.
SOURCE: Dishwasher not spraying
It could be a motor or a pump issue. The dishwasher has a motor that attached to a pump which forces the water up into the sprayer arms and during the drain cycle, it pushes the water out of the dishwasher. The motor (and pump) located beneath the dishwasher. Good luck!

Your machine has detected a "flood" condition and has defaulted to its flood mode. Meaning that only the drain pump will work until the flood is fixed.
Bosch D/W's are pretty slick, the entire unit is sitting inside a drain pan that's designed to catch an overflow (flood) keeping the water off of your floor. This overflow pan has a Styrofoam float that rises with the flood and trips the "flood mode". The water in the pan has to be removed allowing the float to drop back down before you can use your dishwasher again.
There are 2 ways to do this... the easy way and the hard way.
1.) Easy way---> Wait a few days. The water will eventually evaporate out of the drain pan all by itself. Takes longer than the hard way, but no tools are involved.
2.) Hard way---> (not actually "hard") TURN POWER OFF TO THE DISHWASHER! Remove the lower kick panels (below the door). Remove the 2 screws holding the water valve in place, and push the valve up as far as you can. Now use a "Shop-Vac" with a long crevice tool attachment. Stick the crevice tool in where the valve was... make sure to reach in there about 8 or 9 inches, (the safety float is in there on the left, you can see it with a flashlight) otherwise it won't reach the water. Now simply suck up as much water as you can. You won't be able to get it all, you just need enough removed to drop the float.
Now try your D/W... after a normal 2 minute drain, it should fire right up.

I would check the hose/water filters. make sure that you have proper flow from the hoses
SOURCE: Loud Humming noise every time we run the dishwasher
Hi, I had this exact same problem. In my situation it turned out to be the pump that pumps out all of the used water. It was rubbing up against the floor so that every time it turned on it made a loud vibrating sound. I just reached under the washer and put a piece of rubber between it and the floor and it solved the problem.
good luck!
I saw this post because I am considering buying the same model you have. Other than the noise problem you have, what do you think of it?
SOURCE: My dishwasher is making a humming sound and does not rinse?
A humming sound can be a failing wash motor (that drives the water pump) or it can be as simple as a blockage in the the pump area beneath the lower spray arm, under the filter.
Remove the spray arm and the filter top (screws will need to be removed)
Use a flashlight and inspect all over the sump area for debris that is blocking/jamming the impeller area. Reasemble and test with a short cycle.
If the dishwasher continues to make the same humming, it is time to replace the wash pump.
Good Luck! Post back here if you would like more guidance.
