Yes a washer does need a dedicated circuit in order to work safely and efficiently.
Dedicated circuits isolate a single appliance from the rest of the house’s electrical system providing it with a consistent supply of power and preventing other appliances from overloading the circuit.
Size of the Washer
The size of the washer is one of the main factors that determines whether or not it needs a dedicated circuit.
Generally speaking a washer with a capacity of 6.25 cubic feet or less can be powered by a standard 15-amp circuit.
However if the washer is larger than 6.25 cubic feet it will likely require a 20-amp circuit.
To be sure it is always best to consult with a certified electrician to determine the proper type of circuit for the size of the washer.
Age of the Washer
The age of the washer is also a factor to consider when determining whether or not it needs a dedicated circuit.
If the washer is from the 1970s or earlier it is likely to require a separate circuit.
This is because older washers have less efficient motors so they draw more power than newer models.
Wiring in Place
Finally it is important to consider the wiring that is already in place.
If the washer is being installed in a new construction home it is likely that the wiring is already in place and dedicated circuits are available.
However if the washer is being installed in an older home it may not have dedicated circuits.
In this case it is important to consult with a certified electrician to determine the best type of circuit for the washer.
How to Tell if You Need a Dedicated Circuit
The easiest way to determine if you need a dedicated circuit for your washer is to consult your owner’s manual.
It should give you the exact specifications for your washer’s power requirements and tell you whether or not you need a dedicated circuit.
If you don’t have the manual you can also use a voltmeter to determine if a dedicated circuit is necessary.
To do so turn off all other appliances on the circuit and then turn the washer on.
Place the voltmeter leads on either side of the washer’s power cord and read the voltage displayed.
If the voltage is higher than what’s specified in your washer’s manual you need a dedicated circuit.
Pros and Cons of Dedicated Circuits
Having a dedicated circuit for your washer certainly has its benefits.
It ensures your washer will get the power it needs without interference from other appliances and it can help prevent overloads and potential fire hazards.
On the downside dedicated circuits take up more space in your electrical panel and cost more money to install.
They also require more effort to maintain because you’ll have to check them more often for signs of wear and tear.
Final Thoughts
A washer does need a dedicated circuit in order to work safely and efficiently.
It ensures that your washer gets the power it needs without interference from other appliances and can help prevent overloads and potential fire hazards.
While they do cost more money and take up more space in your electrical panel they are well worth the investment in the long run.
