New dishwasher supply line connection

Anybody know the reason why some of the new dishwashers now have a garden hose type factory connection? Seems to be no reason for it and they don't even include the elbow fitting to take you from 3/8 compression to 3/4 garden. Had to run out and get one in the middle of the install. Why?!
 
They have been doing that for years. Used to deliver them and it just depends on the model. One thing be sure to use the stainless line, I've seen many a line crimp and start to leak or cause problems with the dish washer.
 
One would expect that, but I had a hard time with this fitting :) The fat 3/4 part of it gets in the way of final tightening of the compression nut. I had to break out a 5/8 crowfoot, nothing else would do. An average homeowner with an adjustable wrench would be up the creek. Forget making the compression connection first and then slipping on the garden fitting like they show in the installation instructions, you'd kink the copper line.
 
GARDEN HOSE. I hope that YOU are living with the machine. Hoses should be replaced when YOU see water dripping out of the dishwasher. Hope you do not have a flooded floor.

However, most appliances outlive the original purchaser, there days. THREE yrs. is about average for any new appliance, including the washing machine. REF: GE service tech.

When the house is sold, the garden hose hook-up will be included in the new "reverse morrtgage".

Just buy one of these: <a href="http://www.homedepot.com/p/Watts-3-8-in-x-3-8-in-x-60-in-Stainless-Steel-Universal-Dishwasher-Supply-Line-D60U/202309759">http://www.homedepot.com/p/Watts-3-8-in-x-3-8-in-x-60-in-Stainless-Steel-Universal-Dishwasher-Supply-Line-D60U/202309759</a>

You can also just buy the garden hose adapter and adapt it for 3/8 compression.

That GE service tech only sees the broken ones; he doesn't know the percentage of failures as the machine gets older. I used to wrench at a Ford dealer back in the 70's, changed a LOT of ignition modules but I really didn't know if it was one out of a hundred failing or 20+ out of a hundred. Turned out the ones made by Ford Aerospace had a third dying. Hitachi and Philco had one in a couple hundred die.

My Kenmore washer and dryer will be 40 next year, the Sub-Zero, Wolf cooktop, Bosch dishwasher, Creda oven all are 20 years old.
 
GE manual still reccomends a hard copper line. If you do use the new fangled connection they reccomend replacing the line every 5 years.
 
I do work for a company that does fire and flood restoration on homes and a dishwasher is frequently the source of the flooding. I wouldn't use the garden hose type hose. I would use a braided stainless water supply line. Another culprit is a washing machine. Almost nobody turns the water off when they are done.
 
"I would use a braided stainless water supply line."

Funny thing is, though, that "braided stainless steel" supply line is actually a plastic hose with some reinforcing cord in it that's encased in a stainless steel braid and the whole setup is no better than the quality of the crimp at each end (made in "the Land of Almost Right")

I've already had one of them come apart.
 
>I wouldn't use the garden hose type hose.

Stephen, The connection kits sold for this purpose have a braided hose and a 90 degree garden hose adapter. (See my earlier post.) There's no room under a dishwasher to use a hose, anyway. When I installed mine, I just purchased the 90 degree hose adapter and connected it to the existing 3/8" copper line with a compression fitting.

Perhaps I misunderstood what the OP posted. I had a customer have me install a DW and got a hose literally like a garden hose. I talked them out of it and got a braided hose to replace it. Now most all of them today are some kind of rubber hose included the braided hose but that is an improvement over the copper lines that easily kink and break from the units being replaced over the years. If someone would change the line each time they replaced the DW it would help but they usually don't.

I had 2 cone apart I keep a spare on top of the water heater. I concluded they would hold up if it was a straight run with no bend near the crimp so I got a couple 90's so I could get a straight line run. My next move was to get the heater out from under my house and mount it on a outside wall.
 
It is intended to be a more streamlined design and also more leak proof. The reasoning behind this is the use of a repostionable compression type fitting "garden hose end" versus a fixed type "standard pipe fitting". Pipe fittings usually require the use of thread sealant and the knack of getting it tightened just right to match up perfectly with the inlet line or you could have a leak at the fitting or a kinked line, then you have to disassemble everything and start over instead of just giving the garden hose fitting another quarter turn to solve a leak issue. That 3/8 pipe fitting could be adapted/converted to fit i.e. compression, flair, rubber o-ring, various pipe sizes etc. Now the idea is that you go strickly from the garden hose fitting to a 3/8 compression fitting only, thus reducing guesswork on what to replace the line with if necessary without having to already have the dishwasher removed. In a nut shell it is to make installion easier. That is what I was told when I used to sell dishwashers. HTH
 
> In a nut shell it is to make installion easier.

Once you get over your anger at having to make a trip back to the store to get a connector that you've never seen before, the installation IS easier. Using the 90 degree hose-to-3/8 compression adapter, you can bring your copper line in from any direction. And you don't have to turn a wrench in the confined space under the dishwasher, since you can hook everything up before installing the washer.
 
simply use one of those "braided" hoses that go to the comode fitting. 3/8 hand tight on both ends. In the basement I connect to the hot water shut off valve.

The shut off valve could easily be installed under the dishwaher.

Lots of times, the whole house has to be shut down from water, just to fix an appliance.

Care should be considered when laying out the plumbing schematic for any new structure.

Manifold at the incoming water source, mobile home, or standard house could prevent total inconvience to the household during normal routine maintenance of any appliance, including hot water heating systems, etc. Especially on the week-end.

Lots of anziety goes on with the plumbers, household personnel, and others during times of "can't flush".
