Self-Install Diswasher Question

[EdFNJ]

We live in a 2/2 Colony about 13 yrs old with the "standard" Villages supplied Beige GE appliances that were there when we moved in. Time to replace the dishwasher.

I have to assume someone here has done a DIY dishwasher (hey, Mr retiredguy123) replacement, and I want to make sure I get all the parts for the new one and don't want to pull out the old one first.

Question is IF YOU HAVE REPLACED ONE in a SIMILAR HOME do they "hard-wire" these to an existing junction box or did they put in a standard 110V outlet in the back of the existing opening to just plug it in?


TL;DR
All the BOSCH built-ins come with a standard "plug" for a standard 110V outlet but also (optionally) you need to supply their non-standard junction box kit (see attached) for a hard-wire install. I have a done a couple dishwasher installs over the years but the appliance always had a built-in junction box for a direct romex connection. I could just cut off the plug and connect it to the romex if that is what is there but that ain't kosher (not that anyone would look). Their "special" hard-wire junction box kit is this (see photo and note the non-standard connection for the dishwasher end).

!YES! I could just order then return the Bosch box if not needed but I am curious what's behind the curtain. :D

Thanks

I have not installed a dishwasher, but I think you should be prepared for a plug in or a hardwired electrical connection. It could be either. My disposal plugs in under the sink which implies to me that the dishwasher is probably hardwired because the connection is not visible. It seems as though they would have installed the dishwasher outlet under the sink, near the disposal outlet. I would be especially concerned about protecting the flooring from damage when you pull it out. Good luck.

They’re plugged into a dedicated receptacle behind the dishwasher

The NEC requires a dishwasher have their own dedicated circuit, and it’s receptacle not able to have anything else plug in to it.

That is what I had assumed.

If you have a push-pull shut off valve, it should be replaced with a standard ball valve. Some homes were built with that valve behind the dishwasher.

Mine is under the sink and is accessible. A shutoff valve would be pretty useless if it were located behind the dishwasher.

I would be especially concerned about protecting the flooring from damage when you pull it out. Good luck. For sure. It will roll out onto a sheet of cardboard.

If you have a push-pull shut off valve, it should be replaced with a standard ball valve. Some homes were built with that valve behind the dishwasher. Mine is under the sink so if needed I can get to it. That's the only one in the house I didn't replace because it was tough to get at. The bathroom sinks while tight were still easier.

They’re plugged into a dedicated receptacle behind the dishwasher Excellent! Saves me 20 bucks and is a lot easier. Used to be the DW had a flimsy junction box where you'd just pull the romex in through a cable connector and use wire nuts. This is much cleaner.

Ed, is it possible that you accidently selected a European or other foreign connection, instead of the US standard connection?

I cannot comment on your specific house, but every dishwasher i have ever seen plugged into a standard 120 volt outlet.

No sure what you are referring to in first paragraph. It's a Bosch being purchased from Lowes but thanks on the outlet confirmation. That is what I needed to know as it comes with a standard 3-prong plug or per online install manual the "optional" junction box for a romex hard wire conection which is what any previous dishwasher had that I installed. It seems ALL Bosch models are the same.

The one I replaced in our older house was hardwired. The new one came with instructions to either hardwire it or purchase a kit to install a cord to plug into an outlet. I think all new construction requires a cord to outlet configuration. Since I didn’t want the extra work of putting an outlet under the sink, I just hardwired the new dishwasher. Be very careful to make sure the dishwasher is properly leveled to prevent potential leaking. Also, sometimes the new door gaskets can leak at first until the dishwasher is run through a couple cycles and seals properly. I think they get compressed in their shipping mode and need to self adjust after unpacking. Best of luck with the project.

While spending some time working in floor covering, one of my handiest tools was a 2'x4' masonite panel cut to 2- 1'wide strips. Slip one under each front foot of the old machine, and it will slide out easily. Works on any kitchen or laundry appliances to save damaging flooring. Lowes or Homley Depot sells 2'x4' panels, and will cut in 1/2 for you.

Don’t know if this helps but I replaced a dishwasher (myself) in about 2009 in a Colony patio villa that was built in 2002 . It was hard wired. Easy peasy

[Mhope]

Most of the new systems use a corrugated flexible tube to connect the water supply to the dishwasher. The connections and fittings are plastic with squeeze clamps. Give yourself a little peace of mind when you make the connections with a thin smear of pvc glue inside the connection. A slow leak behind the machine sucks.

[JayDub]

I suggested you Google Dishwasher instillation just to get an idea of what your in store for. You should be able to select a specific model regardless it will give you a good idea of what you will need

I replaced my own GE dishwasher a couple of years ago with a new Bosch dishwasher. I don’t remember having to buy any other additional parts for the install. It was pretty easy to do.

[Randyj66]

The most important thing of any dishwasher Installation is the anti siphon loop that is required so water from the drain cannot back up to the dishwasher. To achieve a anti siphon loop, mearly route the drain hose all the way to the top rear of your cabinet then back down to the drain fitting. This insures no way water can back up in the dishwasher, causing smell!

[CharlesNT]

Yes, this is a recent code change. Our dishwasher was recently replaced as part of a kitchen remodel. They just took the romex pigtail and used it to set up a regular outlet. The parts should cost less than $10, and it brings you up to code.

[Ski Bum]

Correct about the anti-siphon loop. I have seen new dishwashers come with the drain hose attached high on the back of the machine. Of course, do not detach it thinking it is part of the packing process.

I have a Bosch. Never have seen that special wiring either.

You should be able to select a specific model regardless it will give you a good idea of what you will need Thank you (and all that replied). Installation is not my concern. I've done a couple before but yes, Google has everything. My only real question was (or is) does The Villages construction wiring behind the dishwasher have a standard ELECTRICAL outlet in a home built ~2009 or does it need to be hard wired so I can "pre-purchase" needed parts and have everything on hand. :D

[NoMoSno]

You may need the 90 deg. compression fitting installed at the dishwasher water inlet.
Take it off the old one if you need it.

Might not be a good idea....
It can melt a hole through plastic

PVC glue is specifically for PVC...

I can't speak for other brands, but our Whirlpool dishwasher has a check-valve on the discharge hose.

I've replaced the hose once when it went bad.

In case anyone other than myself cares :D (since I started this) to answer the ORIGINAL QUESTION of this topic the 2/2 Colony (in Amelia) built circa late 2009 DOES indeed have an actual outlet behind the dishwasher. :1rotfl:
