That machine is beautiful in white! I've never actually seen one in context with an actual kitchen, only on the website. Mine is black, as are the ones at Home Depot, etc., and I love it, but that looks really nice!
You're going to love that dishwasher, but I'm sorry that happened with the installation. :/ We had an issue with Breland while our house was being built, where I told them to leave the dishwasher in the box, and I would install it myself, and just to go ahead and get the hookups under the sink done. She said she would instruct the contractors to do so, but did they? Of course not. We came to check on things after the appliances came in, and of course it was already installed, they had already taken the films and plastic off, and somehow (this is still an unsolved mystery) the detergent and rinse aid sample packet were no where to be seen. They also lost the retaining clips that hold the lower access panel in place. What was worse, however, was the fact that the machine was completely unlevel. You could kneel in front of it and tell that one side was higher than the other, in addition to the fact that the door scrubbed against the cabinet when opened. I was livid, and reported it, but went ahead and detached it and releveled and reinstalled everything perfectly. It's probably the most level and symmetrical appliance installation I've ever done, considering that I'm extremely OCD about my appliances being perfectly level and straight and even with the cabinets.
After we moved in and the dishwasher was being used, I noticed a popping sound everytime the inlet valve opened, but it was coming from the wall. I figured that the pipe in the wall wasn't secured properly, and was moving under the pressure of water kicking on and off, and dismissed it because I knew it would be more trouble than it was worth, until it hit me - our house is on a slab foundation; the pipes don't run through the walls. Upon closer inspection, they had connected my dishwasher with rigid plastic refrigerator line, rated at no more than 100F. Of course, I couldn't remove the DW from the cabinet because the idiots had made three attempts at installing it beforehand, making holes under the counter, and I know that if I take it out again, I won't have a screwhole left. I bought a real braided hose, disconnected the old, and used tape to connect the two and pulled the new through while getting the old out. Now it fills perfectly, with only that nice hiss from the valve.
I know that doesn't have anything to do with paying $500 for an installation, but it just shows that those people will milk you for everything you have while doing the absolute least they can do. I'd call them and demand an explanation.
