    I was able to find a Bosch 500 SHPM65Z52N listed in stock with a delivery date toward the end of the month.
    Looks like I need a 3/4 to 3/4 elbow connector and a 3/8 supply line? Anything else I need to install this? Looks like Bosch uses 3/4 FHT vs 3/8 FHT.

    Install manual says a power cord and the drain hose are included. I have an existing shut of valve for the dishwasher supply line, an outlet to plug into, and a garbage disposal connection. This is a replacement dishwasher water line and connections for the drain hose are there.

    The supply elbow is pretty common now.. was a total PITA 10yrs ago or so.

    Thanks. What are the better quality brands of braided supply lines and elbows the 3/8 to 3/8 compression supply line and 3/4 to 3/8 elbow? Fluidmaster, ProCo, Fluidmaster, etc. are decent?

    All new dishwashers use this fitting. The garden hose type end threads on to the dishwasher, after that it is all the same, 3/8". As Tuttles stated, at one time they were hard to find and I got lucky one day after buying a new dishwasher and ready to install with parts all over the kitchen floor, I found one at Lowe's on the wrong hook. I cannot figure out why the industry changed? I think is was too difficult for some to get a wrench on a 3/8" compression nut under the dishwasher? I have a Bosch DW and this is what is needed.

    I don't know why they changed from 3/8 FIP to 3/4 MHT. also didn't know they all changed just thought it the vast majority. they were pretty easy to hook up before . my guess is making an installation easier would be secondary to cost savings or even quality. they might feel less leaks would occur , less failures but I've not seen a reason for it . I think the MHT adapter x 3/8 90 , came with the D/W but being phased out , I know I've never bought one . I have several of them and cant remember if the D/W includes the 90 (they never came with the 3/8 MIP x comp)
    I believe the solenoid valve with a male hose thread would be cheaper to manufacture than with a brass connection. and could be a factor.

    Thanks for the replies. I ordered the Fluidmaster FB6W60K 60 in. 3/8 in. Connector Kit that includes the 3/8" and 3/4" elbow fittings. Don't need the 3/8 in. will just put in the extra parts drawer. Looks like a lot of the dishwasher install kits now include the 3/4 elbow or you can buy it separately.

    It might have been a maintenance factor. Much easier to unthread the fitting with pliers to pull it out for repairs, etc.

    Fluidmaster site said most dishwashers made after 2009 will have a 3/4" inlet size and it's supposed to make installation easier to align and require less torque to make an adequate seal.

    I looked at Maytag/ Whirpool and Bosch install manuals:

    Maytag/ Whirpool install manual: Other Parts Needed (not provided): 3/8" (9.5 mm) Compression x 3/4" (19 mm) Hose Fitting with rubber seal and 90° elbow (required to properly connect household water line to the dishwasher.) Part no: W10685193

    Bosch install manual: Elbow connection with 3/4” female hose threads on one end and fits your water supply line (copper tubing, compression fitting, or braided hose) on the other. Hot Water Supply Line - Minimum 3/8″ O.D. copper tubing or metal braided dishwasher supply line.

    Other requirements:

    -Minimum of 3, preferably 4 hands
    -Ability to crawl upside down into tight spaces
    -Sailors dictionary on curse words
