Are Dishwashers 110 or 220?

Discover the power requirements of dishwashers: 110 or 220 Volts?

Confused about the electrical needs of your dishwasher? We’ve got you covered.

The direct answer is that dishwashers commonly operate on 110 Volts.

Dive deeper into our article to understand your dishwasher’s voltage options and considerations.

A Bit of History

In the past, most dishwashers used to run on 110 V. This measures the 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 on 110 V and others that run on 220 V.

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

Another problem is the limited capacity for appliances that run using 220 V. For that reason; most manufacturers lean on 110 V dishwashers. Most power installations at home can accommodate up to 120 V.

Can a Dishwasher Be Plugged into a Normal Outlet?

You can plug a dishwasher into a standard 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 it serves its purpose. 

A device known as a GFCI can be installed to use as a connection for the dishwasher. However, you should know 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 must install a GFCI outlet. 

You should install a GFCI receptacle and an outlet using a standard outlet. Ensure your dishwasher works with a GFCI.

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 make plug-in dishwashers because most home power outlets can power up to 120 V. 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 home. Dishwasher accidents are dangerous. 

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

You can use many ways 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 110-120 V, then with no doubt, your dishwasher is a 110 V one. If it suggests 220-240 V, your dishwasher can be powered by a 220 V outlet.

Check the Sign on the Label

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

Check the Nameplate

A dishwasher comes with a nameplate indicating the power required to run the device. If it says to use in a 220 V outlet, your dishwasher is 220 V; if it shows 110 V, it is a 110 V one.

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 120 V outlet. If it works, it means your dishwasher is 110 V. A 120 V outlet cannot power 220 V. 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 110 V. Most home power outlets can power up to 120 V. Unless your dishwasher is a commercial purpose one, there are high chances it runs on a 110 V.

What Type of Plug Does a Dishwasher Use?

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

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


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