I had the same problem. The motor had to be replaced. For as much as we paid for this it has not lived up to the Bosch name. It's never been as quiet as other people talk about, and then the motor went out! It's only 2 years old.

Have you cleaned the traps and run some vinegar through? They build up dirt from kitchen debris over time which causes the pump and spray rails to pick up sludge. You need to clean them at least every 6 months. Check farther on line for cleaning solutions to clean and maintain dishwashers. I have been hearing clr can be used but can't confirm this.
are noticing that the dishes are not clean, then there are a few things to
check for. Check the soap powder if it's kept in a dry environment. Also try
replacing the powder with something like a gel or liquid. Next thing to check
for is the water pressure and fill valve. Check if the water is filling in and
the spray arms are throwing the water with enough pressure. Try and listen to
the sound if you hear a proper spraying action sound.
seems as a low water pressure then check the fill valve. Now, check if
dishwasher is draining the water or not. While the dishwasher is working check
whether the dishwasher is draining and there is not much left out water after
the cycle is complete. Try cleaning the spray arm with a soft brush. The water
temperature plays a major role in cleaning of dishes. The temp should be
between 125 and 150 F for dishwasher to clean the dishes.
this helps... Please post back if you need more information.
ok so If your dishwasher has worked fine in the past but, suddenly, your
dishes aren't clean after the dishwasher completes all cycles: 1) Check your water heater's temperature dial to
be sure it hasn't been changed recently. 2) Be sure dishes haven't prevented the detergent
dispenser from opening properly during the wash cycles or kept the spray arms
from turning, the lower arm from rising, or the spray from reaching the upper
rack's dishes. 3) During the wash cycle, listen to the spray arm
spinning inside. If it seems to be spinning poorly, clean out the spray holes
in the spray arm(s) with a stiff piece of wire; wait for the machine to cool,
and then remove the spray arm(s) by unscrewing the hub cap and lifting the
arm(s) off RegardsGizokieth
if you have a torx 20, and torx 15 screw driver, you an remove the screws from the top plate of the wash motor, and underthere youll see another t15 screw converingthe "chopper" assy, sounds as if a seed, of chicken bone, perhaps apiece of glass hasgottne down there
It is probably a dying recirculation/drain pump. It serves both purposes so is only off when the drying cycle starts.
If the bearings are going bad the seals will probably fail soon too since they will be more stressed by any wobble in the pump shaft due to wear.
How deep do you want to get into this?It sounds like the wash pump motor bearings that are worn.You can pull the unit out flip it over and wd40 the bearings in the motor or you can replace the bearings.Try to lube them first.
It could be the impeller on the motor. The impeller fits over the shaft of the motor and might have split/broken up. That funny noise is probably the shaft spinning inside the damage impeller. Fortunately the impeler is fairly inexpensive and easy to replace. I believe there are one or two parts/covers to remove that are held in by a roughly half dozen torx screws.
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.
