Are Dishwashers 110 or 220?

A lot has changed over the years. In the past, most dishwashers used o run on 110V. This measures the amount of current required to power a machine and the heat generated when drying the dishes. However, due to changes in customer demand, we have dishwashers that run in 110V and others that run in 220V. 

Despite these changes, dishwashers that use 110V can be plugged into a 110V power outlet. A problem arises when using the 220V dishwashers; they can only be plugged into outlets that produce 220V; otherwise, you cannot use this dishwasher.

Another problem is the limited capacity for appliances that run using 220V. For that reason, most manufacturers lean on the 110V dishwashers. Most power installations at home can accommodate up to 120V. This makes the 110V, known as “mercury-free” dishwashers, ideal for any home. 

Can a Dishwasher Be Plugged into a Normal Outlet?

You can plug a dishwasher into a normal outlet if compatible with your dishwashers. However, if your power outlet does not accommodate a dishwasher, you can take a few more steps to ensure your dishwasher is serving its purpose. 

A device known as a GFCI can be installed to use as a connection for the dishwasher. However, you should know that you cannot plug in this device anywhere. 

Check for a diamond-shaped outline with a line passing through it to check if your receptacle is GFCI rated. If it does not have this symbol, you will need to install a GFCI outlet. 

You should install a GFCI receptacle and an outlet if you use a standard outlet. Ensure the GFCI you have works with your dishwasher. 

Are New Dishwashers Hardwired or Plugged In?

National Electrical Code (NEC) has a rule that all new or traditional dishwashers should be hardwired to a power source. This is because of the high current required by the dishwashers. However, most modern dishwashers are plugged in. 

Manufacturers are making plug-in dishwashers because most home power outlets can power up to 120V. Still, having your dishwasher hardwired will save you from many avoidable accidents. 

When power cords can be unplugged, it can be unsafe, especially when small children are in the home. Dishwasher accidents are dangerous. 

How Do You Tell If an Appliance is 110 or 220?

There are many ways you can use to check the amount of power that powers your dishwasher. 

  • Manufacturer’s manual

The first sure way of knowing the voltage of your dishwasher is by checking what manufacturers have indicated. If they say 110-120V, then with no doubt, your dishwasher is a 110. If it suggests 220-240V, your dishwasher can be powered by a 220V outlet.

  • Check the sign on the label.

Your dishwasher will contain a label indicating the power required to run your appliance. If it stated 110V, you could only plug it in a 110V outlet. 

  • Check the nameplate

A dishwasher comes with a nameplate that indicted the amount of power required to run the device. If it says to use in a 220V outlet, then your dishwasher is a 220, and if it shows 110V, then your dishwasher is a 110.

  • Ask your electrician

Your electrician will know if all the named methods do not tell how much voltage your dishwasher runs in.

Other methods are not entirely but can be used to tell the voltage your appliance runs on. You can plug your dishwasher into a 120V outlet. If it works, it means your dishwasher is 110V. A 120V outlet cannot power a 220V. So, if it does not work, it means the latter. 

Are Dishwashers 110 or 220?

Dishwashers can either be 110 or 220. However, since most home power outlets range from 110-120V, most dishwashers used for residential apartments are 110. 

There are instances like big hotels with loads of dishes to do every day. 220V dishwashers are ideal for such cases. 

What Voltage is My Dishwasher?

You can use the above methods to tell what voltage your dishwasher uses. However, of is easy to estimate that your dishwasher is 110V. Most home power outlets can power up to 120V. Unless your dishwasher is a commercial one, there are high chances it runs on a 110V.

What Type of Plug does a Dishwasher Use?

Different states have different electrical regulations. If your state indicates that all dishwashers should be hardwired, then that is exactly how you install your dishwasher. 

Modern dishwashers come with a cord that can be plugged into a power outlet. Check the specification of the dishwasher before plugging it in. If the dishwasher is a 220V, only plug in a 220V outlet. You can also use some power-cutting devices to aid this connection. 


Due to increased demand, manufacturers produce dishwashers that can either run using 110V or 220V. So, if you want a dishwasher for commercial purposes, you are not limited to a standard dishwasher.
