Learn how to install a dishwasher with this video I made for you. Installing a dishwasher is not hard, nor is it rocket science. If you have to remove an old dishwashwer, see my video on dishwasher removal. The hardest part might be buying a new dishwasher and then reading the installation instructions.
How to install a dishwasher, the GardenFork way
To remove the old dishwasher, you'll need a screwdriver, a pliers, and an adjustable wrench. Be sure to turn off the water supply and make sure the power to the dishwasher is turned off or disconnected. Most new dishwashers plug into a wall outlet under the sink, older models may be hard wired.
Hard wired means there is that metal cable attached to the dishwasher or it may be what is called Romex, the vinyl covered electrical wiring. Either way, turn off the circuit breaker that the dishwasher power wire is connected to, then disconnect the power wire. Put wire nuts on the bare wires. If the machine is plugged into a wall outlet, usually under the sink, just unplug it. Simple!
One thing to keep in mind: Have a bowl handy, as when removing the hoses, they may need to be drained. You don't want dishwasher water draining all over the floor.
If the floor has been tiled after the cabinets and original washer was installed, you may have problems getting the old washer out. The new tile floor is higher than the original floor, so the dishwasher can't slide out.
Make sure the insulation wrapped around the new machine is intact and goes in neatly, this is key to reducing the noise of the washer.
A common misconception I see is people using teflon tape or pipe sealant on the compression fitting from the water supply line. You should not use tape on that joint. You will need to use teflon tape on the right angle fitting that comes out of the dishwasher. See the photo below for how to hook up the water supply line. Make sure the right angle fitting points toward the back of the dishwasher. Remember that the dishwasher is hooked up to the hot water supply.
It helps to have a friend help when figuring out how to install a dishwasher, and remember, if all else fails, read directions.
Great video. Wish you had shown how to connect and disconnected dishwasher from the disposal. I've been wrestling with our kitchen sink and dishwasher, and am trying to diagnose the problem. The dishwasher backs up in the sink when it empties during the wash and rinse cycles. I'm wondering if there is a problem in the drain connections. Our sink drain overall is not vented properly, so I installed an air admittance valve, but it still drains slowly and the dishwasher still backs up.
I've snaked the kitchen drain and found no obstruction. I guess I should make sure the dishwasher drain hose is not clogged. When I run the disposal, nasty stuff pushes up through the sink, too.
Plumbing -- can't live with it; can't live without it.
portable dishwasher hooked up to one handled faucet can possiblly get both hot & cold water supply in separate ways when need be?
