Noise in Bosch Dishwasher

The Bosch started making a “fan with bad bearings” type of noise in the last week. My daughter thinks it sounds like a Wookie. It seems to be coming from the washer blade right under the top rack. It is seriously aggravating. Anybody have any ideas? Thanks in advance!

The model number you posted does not come up. Is it American model?

If the noise is coming from the upper spray arm, make sure there is nothing interfering with this arm.

It’s not the spray arm. It sounds like a water pump or something like that.
