How Many Amps Does A Dishwasher Use

How Many Amps Does a Dishwasher Use?

The average dishwasher uses around 10 amps of power. This means it needs its own dedicated circuit of at least 15 amps.

In some households, both the dishwasher and garbage disposal are connected to a 20 amp circuit. However, the National Electrical Code now mandates a dedicated breaker for a dishwasher in all new circuitry.

Can a Dishwasher be on a 15 Amp Circuit?

A dishwasher should be on at least a 15 amp circuit. 15 amps is enough for most dishwashers on their own dedicated circuit.

A dedicated circuit is a plug used for just one appliance, with nothing else plugged into it.

Some dishwashers draw more power than most, and may need to be placed on a 20-circuit breaker. If your dishwasher does not work when hooked to its own dedicated circuit, this may be the case.

Hire an electrician to replace the circuit with a 20-amp or purchase a dishwasher that uses less power.

Does a Dishwasher Need to be on its Own Circuit?

A dishwasher should be on its own 15 amp circuit, meaning nothing else is plugged into the outlet.

This is essential to avoid a short circuit, which poses a danger to your appliance and your household. Short circuits are a fire hazard.

Always be aware of how much power your appliances draw so that you don’t overwhelm the outlet. Some dishwashers use more power than is typical and may need a 20 amp circuit.

What size breaker do I need for a dishwasher?

The size of your breaker will depend on your dishwasher, but most run smoothly on a 15 amp circuit.

Some dishwashers may need a 20 amp circuit, but this is not typical for a household dishwasher.

How much power does a dishwasher use?

A dishwasher uses an average of 10 amps and 1,800 watts. Some use up to 2,400 watts, while others use as little as 1,200 watts.
