But if you buy the dishwasher from a big-box home improvement center or an online retailer, connecting the dishwasher is usually not included—or it may cost you a substantial additional fee to have this done. Fortunately, connecting the dishwasher yourself is a fairly easy job, once the old dishwasher has been removed.
Connecting a new dishwasher requires three connections: a power-cord connection, a water supply connection, and a drain line connection. DIYers can do all of these if they understand what's required. The power connection may be the trickiest, especially if you don't have experience with electrical wiring.
Dishwashers can be "hard-wired" with an NM circuit cable that feeds directly into the wire connection box on the dishwasher; or, more commonly, they can use a standard appliance cord that plugs into a wall outlet. Either way, the electrical code requires that a dishwasher be served by its own dedicated circuit, and if yours is not wired this way, you may want to have a new circuit installed at the same time you are replacing the dishwasher.
Even where not required, this is the better strategy, since it makes it easier to disconnect the appliance if it needs to be serviced in the future. There is no reason you can't wire the dishwasher yourself.
Both hard-wired connections and appliance cord connections are done exactly the same way, with wire connections made inside an access panel at the base of the appliance. The water supply connection is an easy matter of connecting one end of a braided steel supply tube to the water inlet valve on the dishwasher and the other end to a shut-off valve on a hot-water supply pipe. This supply tube is really nothing more than a longer version of the same kind of supply tubes that feed sink faucets and toilets, so if you've worked on those plumbing fixtures, you'll have no trouble with the dishwasher hookups.
Hooking up the water supply tube to the dishwasher usually requires attaching a special brass fitting known as dishwasher 90 —a degree elbow that allows the supply tube to easily connect to the dishwasher.
This fitting is normally included with the connection kit that also includes the braided steel supply tube. Connecting the drain hose on a dishwasher is an equally simple plumbing job. The drain hose connects to the drain trap under your sink; on the way to the trap, it either loops up to the underside of the countertop under the sink or is attached to an air-gap fitting.
The proper method of doing this depends on the code requirement in your area, but either method is intended to keep dirty wastewater from siphoning back into your dishwasher.
As the drain hose loops back down, it is attached either to a nipple on the garbage disposal or directly to a nipple on the sink drain tailpiece. Most of the working parts—both the electrical hookups and the plumbing connections—are located behind an access panel located on the front bottom of the dishwasher. While it is possible to make these connections while you crouch or lie on the floor, most people find it easiest to carefully lay the dishwasher on its back to remove the access panel and make the preliminary connections.
Start by removing the bottom access panel on the dishwasher. Visually identify the power cord connection fittings, the water inlet solenoid valve, and the drain fitting. Remove the cover on the wire connection housing. Thread the power cord into the housing, and make the three wire connections: green wire from the appliance cord to the green grounding screw, white neutral wire to white dishwasher lead, and black hot wire to black dishwasher lead. These connections are normally made with twist-on wire connectors wire nuts , but some appliances may have different methods for making the wire connections.
Replace the cover on the wire connection housing. You may be able to do this yourself, but it's probably worth hiring a professional, in case you damage other parts of your kitchen in the process.
Next, you need to consider your counters. Steam and water spillage from your dishwasher can damage laminated benchtops, so it's important to ensure the undersides of benches are sealed to minimise the risk of water damage. Finally, most dishwashers particularly built-under models are heavy, unwieldy appliances with lots of sharp edges, so practise safe handling procedures.
Ideally, have a friend or family member help you when carrying it into the kitchen. Skip to content Skip to footer navigation. Top of the content. How to install a dishwasher Whether you're replacing an existing dishwasher or installing one from scratch, these steps will help you get it right. Ashley Iredale. Last updated: 09 December Need to know Replacing an existing dishwasher is a relatively simple job if you're handy with a screwdriver If you're installing a dishwasher for the first time there are some rules to make sure your installation is safe and legal.
Text-only accessible version. Measure your cabinetry to make sure your replacement dishwasher will fit before buying. I did a rough measurement and its like 21w by 27 ht. Under the cabinet was not tile as their is in the rest of the kitchen. I have all electrical and plumbing complete but the dishwasher is having fitting issues. I have a Kenmore with top mounted controls. Are these controls to be visible with the door closed or must they protrude out from the counter top and be visible with the door shut?
I do not seem to have any room to screw in the top metal secure latches. My counter top is laminate and it has a lip that lowers. Right now the controls on the top of the door are visible when shut. Does this need to be pushed further in? When I do push it in the door gets caught on the counter top. How much of a gap should I have from the counter top to the inside top of this dish washer? If you have the installation instructions for the dishwasher they should explain where the top-mount controls should appear probably not visible with the door closed.
Like Danny explains above, dishwashers come with adjustable feet that allow raising it to be flush under the counter. Be sure that yours are turned all the way in so the dishwasher is as low as possible. We are replacing laminate counters with granite counters. We are replacing our old dishwasher with a new dishwasher. The salesman at the granite counter company said we needed to get a side mounted dishwasher and to have it installed prior to installation of the granite countertop.
The dishwasher installer advised us to remove the old dishwasher and install the dishwasher after the the granite installation. These are two different companies. Who is right in this? Should we install the granite countertops first or the side mounted dishwasher?
Please answer soon. We are having issue with installation of new Bosch side mounted diswasher. Does this make sense? We are NOT replacing the floor tiles or the base cabinets. We are installing a new tall-tub dishwasher. The printed instructions say there must be clearance between the motor and the floor, but do not specify how much clearance.
Is this adequate or does this create a safety hazard? When we had a new dishwasher installed to replace an older model, the installer ran the drain hoses through the cabinet next to the dishwasher instead of through the empty space under the cabinet. He claimed that it was because all the new dishwashers are required to use less water and that to make this work the water supply and drain lines need to be above floor level. Is this true or did we get taken again? I lost cupboard space and am not happy about this.
Vicki E. The water supply and drain hoses run through empty space under the cabinet. I wish I could see the hose so I can figure out if the leak is coming from a loose coupling, a split hose, or something else. Can you use a pigtail so you can plug into the wall outlet instead of hard wiring with romex into the outlet box? This was very helpful information,well laid out with pictures showing everything.
I know now this is going to be a easy install. The water line hookup on the dishwasher end now consists of a blue plastic threaded nipple onto which attached is a hose fitting from the supply. Are all dishwashers going this direction — using plastic rather than brass??
Most water inlet valves are plastic and yes they fit up with the brass hose fitting. That is the way of the manufacturers and what is being made for todays dishwashers. Great site! It most likely could be a plugged up dishwasher drain line. My unit would run until the water level float switch kept shutting it off to prevent a flood on my kitchen floor. It was doing what it was designed to do, by shutting itself off. I ended up completely removing the dishwasher drain line, took it outside and blew out some yukky stuff with garden hose water pressure.
The original drain line was not installed properly which allowed food from disposer to back up into dishwasher line and clog it. Using a zip tie to elevate drain line right before connection with food disposer, will help to prevent clogs!
Your picture shows braid covered tubing, next picture has unbraided PVC tied to the water solenoid. What up with that? Since hook-up vary for different dishwashers, we included photos from more than one dishwasher in the article to give readers a different look. We wash by hand usually so it is not often we use dishwasher. I should not have to unclog that line every time i want to use dishwasher, there must be a way to prevent the disposal from pushing food into that hose?
The original water feed was through a copper tube. The dishwasher never finished its cycles. Could the inner diameter of the hose be a problem?
Otherwise, you would get more or less water in the dishwasher depending on your water pressure. Hi, I am going to install a dishwasher in my apartment. The water supply under the sink is made out of copper pipes.
They are like a upside down T. This end is closed so I will have to cut it to open it. Hi Dany, The easiest way to install a shut off valve on copper pipe is to get one that uses a compression fitting.
The other option is to use a shut off valve that is soldered to the copper pipe using a propane torch. Good luck with your project!
The instructions say to put an air gap in for such a case. Two have said to put in an air gap. Can it be mounted within the dishwasher space and under the countertop to avoid visibility? My other question is, how far should the kickplate stick out from the rest of the cabinet kick area? I usually see it flush with the cabinets in the stores, but is that because they are different models?
Can a dishwasher be installed in an island with no sink. The drain line would have to go under the floor of the kitchen no basement and come up through the floor and then into the drain pipe above the trap.
Will this work or should be install a prep sink for the drain line to be closer in the island? Also what is an air gap?
I recently bought a Fleetwood doublewide mobile home. It has no dishwasher. The cabinet next to the sink from what I can gather is for a dishwasher. Can you give some advice on how to proceed? Electrical, plumbing…do I have to get a carpenter to remove the cabinet, an electrician for the electrical work and a plumber to install?
Any help would be greatly appreciated. I havent seen this solution to the problem of water left in the dishwasher,But if the garbage disposal is not completely empty, the pump on the d. Try running the disposale befor useing the dishwasher. If your dishwasher is not draining completly your drain line for the dishwasher is probably clogged and not allowing all of the water to drain out. In other words the water draining from the dishwasher has nowhere to go because of a blockage in the drain so its coming back up into the washer… I would check the drain hose of the dishwasher for any blockages, and if thats clear maybe have the line that the washer drains to snaked out.
It cannot be shortened given the design. Can I loop the hose under the sink before attaching it to the air gap connection? How far should you push back your dishwasher when installing it?
Is it ok for the dishwasher to touch the drywall behind? My problem is the space for the dishwasher is not long enough so If i leave about an inch behind, the dishwasher will protrude a little. Will there be mold or rotting problem if I push the dishwasher all the way and it touches the drywall behind. I am worried because dishwashers run really hot temperature. I live in a building app.. Hi, I just installed a dishwasher and the connection to gargage disposer is leaking.
I tried to tighten up as much as I can as well as well adjust the clamp too, still can not get rid of a small leak around the hose connection to garbage disposer.
Any idea what I can do the prevent leaking? Danny, This is a Great source for info. Much appreciated! Our dishwasher has water that keeps building up at the bottom when we wash dishes. We just moved into the house and are thinking the previous owner installed the dishwasher incorrectly. All of the hoses are down low under the sink and we read somewhere that said they should be higher up. Is that true?
If so, what can we do to fix it? Some local building codes also require the installation of an air gap in the countertop or sink to further reduce the chance of siphoning.
But the new unit says:. Is my quarter-inch supply line too small? Your descriptions have me feeling confident again. We just installed our old built-in dishwasher and the water is spraying both into the dishwasher but also all out the side of the dishwasher where the fill hose is… Any ideas on what is wrong??? Just installed new dishwasher. Hooking up the drain connection, I noticed there is a small plastic sleeve on the inside diameter of the drain connector, that looks like a potential blockage.
Instructions make no mention of the plastic sleeve. I pulled in out once but put in back in, Unsure…? Water coming out of the air-gap. I have installed 2 dishwashers in two different locations, one had no problems but the other keeps spilling out the water from the air-gap onto the sink. I asked a couple of plumbers and they said it has to do with either a clogged drain or the drain hose needs to be above the trap. New drains and both are above the trap.
If that is the case then there is nothing I can do short of tearing out the drain from the wall and lowering it. If there is anyone out there that has another opinion please let me hear it. When installing a new dishwahser in an older house that currently has a copper line as opposed to a wetal line. Will the valve connected to te coppper line be compatable with a metal line?
Now the whole is stripped. Once glue is dry , you will be able to put in screws , and it will hold. I personally would pre-drill a small pilot hole before screwing in new screws. I just installed a Whirlpool dishwasher for my son.
This model has a garden hose connection for the supply line. When supply was turned on there were no leaks. About 5 min into the wash cycle the GH connection to the supply solenoid started to leak. I am thinking I should have used flexible hose connected to GH elbow. What is your opinion of what may be causing the leak. Are the threads on a Bosch dishwasher water inlet valve metric? I am getting ready for the change-out. I bought a kitchenaid. Will it still be able to be installed?
I just installed a dish washer for my nephew. My first in about 8 years. He has Granit counter tops. I reminded him to be sure they put in the threaded incerts to mount the unit. OK live and learn. I used a screw and washer for a temp. I have a old dishwasher -installed in still works, but is not secure and when both top and bottom rack are pulled forward, the dishwasher tilts forward.
There is no place on the top to secure it. Any suggestions??? Is their special screws for this and are their spacers available that go between the dishwasher and cabinet for these mounting screws.? Just had a new whirlpool dishwasher professionally installed to replace the one which was installed when the house was built.
The new washer is not quite as wide as the old one and there is a half inch gap on the side between the cabinet and washer. What can be done to hide this opening?
My wife wish to install the dish washer on high level, I mean to be installed 1 meter above the kitchen ground, is this correct? Thanks to advise. This website is great! I checked other sites but they were not as detailed for my needs.
Hi Roger, Glad to hear our article was helpful. Good luck with your dishwasher installation project! Instead of mounting to the counter top with screws. Once can also mount it through the floor. Many dishwashers have drilled holes on the metal feet for that purpose. Very stable and quiet! After getting new granite countertops put in, the plumber broke the install brackets to my LG dishwasher.
I need new ones. Any help on finding some? LG was no help. We had a complete kitchen renovation done, including having our old Smeg dishwasher installed under counter and plumbed in. Previously, it was on wheels and we would roll it to the sink and screw it to the tap installed under the sink.
The new installation was done by a plumber who extended the drain hose. Does the drain hose need to be from a specific material? To me, what was installed looks like a clear reinforced garden hose.
I am installing a dishwasher into my home. There is a spot for the dishwasher to go and I have all of the equipment to actually hook the thing up. The dishwasher has a plug, however there is no outlet where the diswasher belongs; just wires hanging out of the wall with wire nuts on them.
Should I install an outlet, or cut the plug off, strip the wires, and install? Any suggestions would help. The dishwasher cannot fit near the sink and the sink is essentially on an island or short wall.
There is a vent stack in the wall behind the proposed dishwasher area that has nothing draining into it it was for the old sink. My kitchen sink has 4 holes, so I bought a new faucet set that would use the 4th hole for a pull out sprayer. My handyman says the 4th hole should continue to be used for the dishwasher thing that is already installed there in the 4th hole for overflows? Is it really necessary or prudent to keep it?
The dishwasher is a very basic General Electric PermaTuf that was installed in Thanks for your thoughts. Sink has four holes,one which is used for the dishwasher drain air gap.
Will this cause any problems in DW drainage??? A few months ago, we had a new dishwasher installed. Due to the layout of the kitchen, the dishwasher couldnt be installed flush with the cabinet. It had to be installed at a slight angle and the installers had to bend the brackets at the top in order to angle the washer to where it needed to be.
We had to sign a waiver acknowledging that they were unable to properly install the unit. Is there a way to reinstall this? We dont have any brackets up at the top anymore. My husband wants to screw a metal bracket into the front of the cabinet and I wont let him. Please help.
I have the answer to my November 16 question. No sprayer for me, because the local building code requires my dishwasher to have the air gap.
Too bad. Hi Dana, Thanks for the followup. Do you think it will fit? It did not have a dishwasher before and was a super easy install, but I have water coming out the air gap when the dishwasher is draining. I see that a number of people have posted the same problem, but no one has posted a solution. What can be done to stop the water from coming out the air gap? The only spot I have available is between the sink and the stove. Can I tap into one leg of my electric stove for power?
I have recently moved into a house that already had a dishwasher installed. I wondering what is wrong with the dishwasher it runs but no water is coming into the appliance was wondering if something is missing off the dishwasher and is something wrong with the dishwasher.
Bob, The gasket should come out pretty easy, then you would need to get a matching one from an appliance store. Hope that helps, Ben. Where is the information concerning the vent on the top of the door being blocked by the countertop? Proper venting is needed for both dishwasher performance, and so that steam does not ruin the countertop. People have rationalized the placement of the control buttons, but how does one explain the placement of the vent?
