I recently purchased a Bosch Dishwaster because I have a Bosch Washer and Dryer and am extremely pleased with the quality of the product and performance.  After installation of the dishwasher, the first few times I ran the dishwasher, I would go up to the front panel & touch it to feel a vibration because it is so quiet I couldn't tell if it was running or not.  Will recommend BOSCH products 100 time over.
