Dish Washer installation with easy water draining for freezing conditions
Instead of hooking up to kitchen sink hotwater line can one hook up to a basement hot water line that is drainable to a drywell.
Also instead of hookong up the dish washer water drain to the kitchen drain one can hook up to a basement drain pipe that also feeds to a dry well.
With the water turned off and antifreeze solution added to the Dish washer can one operate the dish washer to circulate the antifreeze solution through the water pump assembly.
Is this a workable solution to prevent damage to the dish washer water pump?

If you mean a line below the dishwasher with a drain down on it the answer is YES

The answer to that question is NO, by doing that you no longer have an air gap or high loop in the drain line (that hook up is for safety) plus by running the line down it could create a siphon and drain the water out while the washer was running.

The answer to that is MAYBE you would have to use a POTABLE anti-freeze, you can't use a standard auto type anti-freeze
Yes * 4, with caveats.
-- There is a danger that some water will be retained in the valve. How significant depends on the specific design.
-- You can drain to the basement so long as you provide an air gap at the usual height -- but provide a second air gap just above the trap to meet strict code requirements. And there are many models of DWs that don't require the traditional air gap, IIRC, though most probably expect the drain point to be at sink level (and some codes require the air gap even if the DW doesn't). Alternatively, add a trap at the usual level (or use a sink trap) and fill it with antifreeze.
-- Obviously, you have to add enough antifreeze and circulate it properly. Details on this will vary by design, and some units will be trickier than others.
-- Probably it would be best to contact the manufacturer and inquire about freeze-proofing procedures.
