We ordered the replacement dispenser and it was very easy to replace. The videos were helpful. Here is the cool part though: I ordered it, and forgot that I did so I ordered another. The money hit my account. AppliancePartsPros contacted me to see if I really wanted two-they don't charge until it ships. She quickly cancelled the extra, saving me a lot of hassle.
Next, after installing the part, we noticed that the dishwasher didn't leak anymore-bonus repair!
