Well for one thing with a Miele ...its small capacity wise. True they are great machines but the price is a tad much. I spent $2k for the LaPerla and that lasted me almost 10 years. The thing with Miele is that when they crap the bed, and the one I had with the main control going and them wanting a cool $1k to replace I thought nope not going to happen. they had already "goodwilled" the motor assembly and the delivery tubes for the middle and upper wash system. That alone would have cost me $650 just for the motor, pump, heater, switches and what ever else was in that module.
The LG 5545ST that I have now is almost 3 years old and I found out that its a common issue with cracks in the control panels, rusting racks and in places that you wouldn't even think of. Then there is the issue with the panel itself where I will press the Power button to power up and it doesn't respond like it used to...it takes 4 tries and then it powers up. I know that is a common issue as well. The LEDS for the time display has blinked a few times during a cycle. As much as I do like this machine and I wish that they were as good as their laundry products, dishwashers are a tad lacking in durability and reliability. They really need to up their game in that area.
