We recommend to never use an extension cord to connect your dishwasher to an electrical outlet. Yes, using an extension cord will work, but it's extremely dangerous. Your power cord will eventually overheat, causing your cord and anything surrounding the cord to melt.
Correct Plug Type
Most heavy-duty household appliances, such as geysers and dishwashers, use 15-amps three-prong cord. The center prong is the ground plug which prevents electric shock by a device that has short-circuited or loose wire inside it. The cord you buy for your dishwasher must have three prongs.
Large Kitchen Appliances (Refrigerator, Dishwasher, etc.)
These appliances are so high-powered that they'll easily overload a poor, little power strip. Plug your large appliances directly into the wall. Do not use a multi-outlet converter to plug in more things, or you'll risk tripping the circuit.
If the power strip or extension cord feels hot, that is a sign that it is overloaded and may start a fire. Rule two: never plug high power capacity appliances, like space heaters, refrigerators, or microwave and toaster ovens into power strips or extension cords.
Toaster. Here's the clue: It has exposed wires inside those slots that heat up to become red-hot. It takes a lot of current to fire up those wires, which can easily overload a power strip. So, no, do not plug your toaster into an extension cord or power strip.
Dishwashers are hardwired. They consume a relatively high amount of power, so it is not advised to use the same method to connect your other household appliances.
Drill a 3/4-inch hole in the back of the right side of the cabinet where the dishwasher is being installed. Sand the edge of the hole smooth with medium-grit sandpaper. Run the dishwasher wire through the hole and into the wiring junction box.
The dishwasher's hot (black) and neutral (white) wires are the ones going into each wire nut from the left side.
The dishwasher circuit needs to be dedicated to 120/125-volt. A 14/2 NM wire is fed into this 15-amp circuit. You can also feed the dishwasher with a 20-amp circuit using 12/2 NM wire.
According to the electrical code, the dishwasher should be on its own circuit. The dedicated dishwasher circuit can't supply any other appliances, lights, fixtures, or outlets. In addition, the circuit that is servicing the dishwasher also needs to have a circuit breaker with at least 15-amps.
Kitchen dishwashers installed in dwelling units require GFCI protection whether hard wired or cord and plug connected.
A hardwired dishwasher is one that's connected directly to your household power supply without a plug. As a result, the appliance does not receive its power through a wall socket or any other electrical receptacle.
Rule two: never plug high power capacity appliances, like space heaters, refrigerators, or microwave and toaster ovens into power strips or extension cords. These appliances have higher power capacity and need to be plugged into a wall outlet directly.
Refrigerators are expensive upfront but will last you decades if you take care of it right. I highly recommend that you should invest in power protection equipment such a power surge protector to safeguard your investment and to prolong the usable life of your refrigerator.
You cannot plug a fridge into an extension cord. The average fridge draws too much power. Your refrigerator will overload conventional extension cords and power strips. This is why manufacturers encourage homeowners to plug fridges directly into a wall outlet.
Unlike plug-in appliances, a dishwasher must be hardwired and hooked up to the home's plumbing. If you're for the challenge of installing it yourself, you can save a lot of money.
The receptacle for a built-in dishwasher shall be located in the space adjacent to the space occupied by the dishwasher.

Yes, the dishwasher and garbage disposal can run on the same circuit. But they are more preferred to be powered by two different circuits rather than one.
Each dishwasher comes with a junction box (with power cord) to be installed in a cabinet next to the dishwasher cutout. It can be installed by an installer, servicer, technician, electrician or other qualified professional and is intended for hard-wired installations.
Household dishwashers use 10 amps of power, mostly. Having said that, your breaker should be on a higher rating than the appliance being used for safety purposes.
The non-metallic (NM) designation refers to the outer sheathing that bundles individual wires together like a cable. This is in contrast to metallic sheathed cable or conduit wiring, in which the bundle of individual conductors is protected by some form of a metal coil or metal conduit.
Currently, many big box stores have the UF-B marked less than the NM-B cable. That's because the price is not as inflated from demand like NM-B. NM-B is also used more frequently because it is WAY easier to work with.
