Repair videos on AppliancePartsPros.com are tremendously helpful. I bought a used Bosch dishwasher and used the video for replacing/repairing the circulation pump and discovered my pump was rusted from not being used. A quick turn with my hand and it was unstuck and working again. Once the dishwasher was circulating water, I discovered water leaking from the door. I ordered the door gasket and had it in less than 24 hours. Great site and service.
