The last time I saw some LG models at Home Depot, they didn't have the one with the flatware tray like yours, Eugene. I wonder if it's been discontinued or HD just didn't carry that model now, I've not kept up with LG's offerings other than what was in the store.
I know they've had their share of "birthing pains" with parts, service, etc. but even those I know have had trouble and service woes still love their LG dishwashers. You've had no trouble at all, right? It's impressive for sure, the space is well used for sure.
I couldn't find any data on the water usage of the new GE, unless I missed that in the tech. data & manual.
Skepticism thrives when it comes to anything new and from GE, they haven't had the best track record over the years for dishwashers - especially the middle and lower-end models.
