How do I install a Bosch Dishwasher? Is there a secret?

This topic is available here on The Repair-Place forum
Yes, there is a secret to installing a Bosch dishwasher. Let's get there together:

First, There is a very small amount of electrical wiring that needs to be done. If you're uncomfortable or unsure how to hook up household electrical components, you should call for help from someone who is experienced to show you how, at least the first time!

These are the steps to installing ANY dishwasher in an existing space, in other words replacing an existing dishwasher:

1) Turn off the electrical power to the dishwasher at the breaker box.

2) Turn of the hot water supply under the sink that goes to the dishwasher, and remove the hose from the supply. Make sure that the hose can freely move out through the hole in the cabinet so that it leaves with the old machine.

3) Locate the screws that are holding the dishwasher into the cabinet. In most cases there are 2 small screws up under the front of the counter, but sometimes they are screwed to the sides of the cabinet, but again, up near the countertop. Remove them!
***Note: I am told that some are screwed down to the floor near the rear feet instead.

4) On most dishwashers, there is a trim panel below the main dishwasher door. Behind that panel there will be a small electrical box closed with a small screw. In there, the electrical connections are made, probably with wire nuts. Open the little box and loosen the wire nuts and disconnect the electrical. The ground may be screwed to the box, or may be clamped together. Use your ingenuity in disconnecting Very Happy.

5) Remove the drain hose from the side of the garbage disposer, or the side of the drain above the trap if there is no disposall.

Slide the dishwasher out.

To install the new dishwasher

1) Install a NEW water supply line from the hot water supply under the sink and feed it into the dishwasher opening.

2) Ensure the wires are also in the correct space. You should probably prepare the electric wires at this time, to get them ready to be attached to some new wires. Cut the old ends off and strip back the insulation as appropriate.

Here is the secret! In the installation manual, there will be precise measurements as to where the channels are for the electric and the water supply. Following those measurements, TAPE THE WATER SUPPLY LINE AND THE ELECTRICAL SUPPLY DOWN TO THE FLOOR IN THE LOCATION INDICATED IN THE MANUAL. This step will save you at least 30 minutes and many cuss words trying to figure out how to fish water lines and electrical lines under your new dishwasher.

3) Slide in the new dishwasher halfway and feed the attached drain hose into the under the sink area, then continue sliding the dishwasher in as you pull the drain hose through the hole in the cabinet.

4) Hookup the drain hose to the side of the disposer or above the drain trap. The drain hose MUST be attached at the back of the cabinet at least at a certain height above the floor. This prevents dirty sink water from entering into the dishwasher through the drain hose. In fact, some localities require an air break on the top of the counter for the drain connection so check with the local inspector.

5) Make the water and electrical connections on the dishwasher.

6) Make your final position of the dishawsher, amke sure that it is flush with the cabinets and then level the dishwasher as outlined in the manual.

7) Install the mounting screws that stabilize the dishwasher in the space.

That's it!
Here is a good question... what if the countertop is not screwable??
I have a granite c-top installed and now I need to install my new dishwasher. How do I attach it up underneath? The granite people say to just glue it with RTV or Silicone. But that can't be right?!
The Bosch dishwashers come with a set of brackets that can be used to secure the dishwasher by either screwing up into a traditional countertop, or to the sides of the cabinets on either side of the opening.

As far as "RTV or Silicone" goes, I have no idea. What do I look like, TheGuru? Laughing
hi, i installed a new bosch dishwasher, and everything went fine until the elbow hookup for the water. i had to keep tightening it to stop a drip, and i eventually ran out of room, as the input connection was facing down. this left no room for the flexible hose to connect. can i safely go all the way around again tightening the elbow? the manual says not to overtighten, so i dont want to break it.

thanks for your help

Hi,

Maybe you could try adding some Teflon tape around the threads of the connection so that it doesn't drip. Wrap the Teflon tape in a clockwise (when looking from the thread end) direction, about 4 winds.
Installing new Bosch SHE44C02UC and the installation manual makes no mention of which of the 2 exterior hoses is the drain hose nor are there any diagrams of either of the two hoses. On the right side of the washer is a flex hose connected dead center in the right side wall (halfway up, halfway back) and was shipped with the hose looped up and back down with the loose end tucked behind a metal panel near the bottom of the right side. What is this hose for? Does it need to be connected to anything?

The 2nd hose is mounted at the rear of the unit and the hose is connected near the bottom of the unit and is the one I assume is the drain hose. It was also shipped looped up and back down and suspended at the top of the loop by rubber band with the loose end just hanging. Is this the drain hose?

I just bought a bosch dishwasher. The hose on the right doesn't get hooked up to anything. It's for air. The drain hose is in the back. As far as the water supply connection, I had the purchase another elbow fitting because the elbow was pointing in the wrong direction when it was tightend. I bought one at a local hardware store. Make sure the threads starts on the opposite side on the one you have.
I just installed a Bosch dishwasher. As for the hot water supply connection here is a tip: use pipe joint compound on the elbow thread then put on several winds of teflon tape..it will guaranteed not leak and you do not need a lot of turns of the elbow.
I hope this will help.
Thanks much for the installation tips. The "secret" of taping down the electrical wire was the one biggie! You were absolutely right, it saved me 30 minutes of and frustration.
Using your guide the install went perfectly and we're now happy Bosch owners!

I've had a bosch shu33a for about five years now. Recently the dishes were not coming out clean and there was clearly a slow drainage problem. The filters were fine and it seemed to be running well. I noticed a lot of slack in the drain hose under the sink, so I pulled the unit out.

The factory adhesive holding the drain hose high on the back had failed and I no longer had protection from sink drain backup (as per your instruction #4). I clamped the drain hose to the wall as high as I could and now everyone's happy.
Installation of Bosch SHE55P dishwasher.
Our new dishwasher should be delivered in about two weeks.

The distance from the dishwasher to the garburator drain inlet is about 10 inches longer than the drain hose that will be supplied by Bosch.

Our present dishwasher (20 year old) has a black rubber hose (of the required length) with an outside diameter of about 1 inch. Could I use a new version of this type of hose rather than trying to get an extension for the hose supplied by Bosch? I can see that the rubber hose can be connected to the garburator drain inlet without any problem. Should I anticipate any problem attaching that type of hose to the dishwasher?

Many thanks
Does anyone know the size of the elbow fitting for the supply line?
