Where Should the Outlet Be for a Dishwasher?

Your local electrical codes can determine where you place the dishwasher outlet. However, for the sake of this article, we will look into the regulations laid out by NEC about dishwasher installation.

Dishwasher installations require basic plumbing, mechanical and electrical knowledge. If you lack these skills, hiring an installer would be better. However, you should know that most dishwasher brands do not offer a warranty for damages resulting from wrong installations.

The installer should have the NEC installation codes when installing a dishwasher in your kitchen. He should also leave you a copy of the regulations for future reference. Let’s get started.

Since a dishwasher is a heavy-duty appliance, its circuit should be separated from the two courses installed on top of the kitchen counter.

You should read the manufacturer’s specifications to know the type of outlet you will install for your dishwasher. If your dishwasher is rated as 110V, your outlet should be 120V. Most dishwashers require 20 Amps to run. So, your receptacle should be 120V 20 Amps.

Dishwasher Outlet Location

A dishwasher outlet should not be placed behind the dishwasher.

You will need to access the outlet to switch it off and on. Therefore, the dishwasher should be plugged into the power outlet fixed below the kitchen cabinet. How high the outlet should be installed will be discussed in detail.

The outlet should also have a Ground Fault Interrupter (GFI). Interrupters detect when the flow of current changes in case of faults in the system. These safety devices have internal switches that stop current flow when they see an abnormality.

How High Off the Floor Should a Dishwasher Outlet Be?

NEC regulations require the dishwasher outlet to be not more than 20 inches above the counter and 6-18 inches below the kitchen sink. 

I have seen some dishwasher outlets passing through the kitchen cabinets in the garage. No rule prohibits the outlet from being in another room. You should, however, ensure this outlet is connected to GFI for safety purposes. 

Check how long the cord is before choosing to install the outlet. According to NEC, local codes, and ordinances, the power cord should be a minimum of 54” and 61” maximum.

Can a Dishwasher Be Plugged into a Standard Outlet?

You can install a dishwasher into a standard outlet if it has a voltage that can power your dishwasher. Most normal outlets have 120V and 15-20 Amps. If your dishwasher is 110, you can plug it directly into the standard outlet. 

For 220V dishwashers, install a GFCI receptacle and use extensions. 

What Outlet Does a Dishwasher Need?

Many people think you can connect any appliance if your home has an outlet. This is further from the truth as most home appliances require a different amount of current to power the device. Home outlets also have their current rating that they can handle. 

Most dishwashers are rated 110V. You can therefore connect them to an outlet with a 120V. To ensure safety when using this large appliance, install a Ground Fault Circuit Interrupter.

Can You Have a Junction Box Behind a Dishwasher?

Yes. You can install a junction box anywhere so long as it is accessible at all times.

However, putting a significant appliance like a dishwasher in front of the junction box. You cannot also put a wall hiding your junction box. Hide the junction box using a white sheet or any of your kitchen colors for safety and aesthetics. 

What is the Code for Wiring a Dishwasher?

Dishwashers can either be 110 or 220. So, depending on the dishwasher you have, match it with wires and outlets that can accommodate your appliance. 

Most dishwashers require a 120 Volt and 15-20 Amp circuit. The circuit is fed using a 14/2 NM for 15 Amps and 12/2 for 20 Amps. Regarding the NEC revised rules, all kitchen appliances should have a ground. 


Before connecting your dishwasher to an outlet, check if the outlet has the proper standards following the National Electrical Code. Check the manufacturer’s dishwasher specifications to know what outlet you need.

Install the outlets preferably 6-18” inches above the ground for under-sink dishwashers. You can also install the outlet in the garage if the power cord is long enough.
