Kewl Darren!
That is one of the best models around if you ask me. Though I love the BOL stuff as I've mentioned, and I also really respect the TOL machine I just got, for many a BOL lacks a lot of usefulness, and the TOL stuff is over-done and overly complicated.
This machine has just what it needs. Plenty of temps, a big capacity tub, all the cycles you'd want (except second rinse, but that seems less and less frequent for me with lower suds detergents) and decent water levels. I find a machine in this capacity with only three levels to be a pain because I always want something in between medium and hi, but 4 or 5 levels seems to address that so I don't have to go back and adjust rinse water.
Interestingly, you can tell this is a large capacity machine (or that the panel was borrowed from one) by the four water levels. With one exception, all standard cap black panel machines had three or fewer levels, and that one exception was an infinite level.
The buzzes and vibrations in the control panel are very common in these machines. You may want to tighten the 6 rear access panel screws. If they're stripped or already tight, you can line the top of the access panel with a layer of black electrical tape and fold it over the edge of the panel. This will stop or quiet the vibrations.
Nice washer Darren! Let us see more sometime soon!
