How much water a dishwasher uses
How much water a dishwasher uses depends on many factors including size (due east.g. Compact or Standard), cycle blazon and efficiency.
Former inefficient dishwashers can use up to sixteen gallons of h2o per cycle, while modern efficient dishwashers use 3.22 gallons on average.
Mod dishwashers are much more efficient than older models every bit they use more efficient jets, rack designs and have many other water saving features.
Energy STAR certified dishwashers use 1.64 gallons to 3.five gallons of water per cycle.
Given their operation, and the increasingly free energy conscious consumer, Energy STAR certified dishwashers are condign the standard on the market place.
For this reason, in guild to more accurately assess today's dishwasher water usage, I'll just focus on Free energy STAR certified dishwashers in this commodity.
So, let'southward take a look at how much h2o these dishwashers use in more detail.

How much water does a dishwasher utilise per bicycle
Modern dishwashers use iii.22 gallons of h2o per cycle, on average.
Overall, dishwasher water use ranges from 1.64 gallons to 3.5 gallons per bicycle.
The most common dishwasher water usage is 3.5 gallons per bicycle.
The table below summarizes how much water, in gallons and liters, dishwashers use per cycle.
| Water usage category | Water use per cycle in gallons | Water use per wheel in liters |
| Average | 3.22 gallons | 12.17 liters |
| Most common | 3.5 gallons | 13.25 liters |
| Highest | three.5 gallons | xiii.25 liters |
| Everyman | ane.64 gallons | 6.21 liters |
How much water a dishwasher uses increases the more than information technology's used. The U.S. Environmental Protection Agency'due south ENERGY STAR assumes 215 dishwasher cycles per year when estimating dishwasher power consumption. And so let'southward follow arrange to piece of work out dishwasher water usage per calendar month and year.
How much h2o a dishwasher uses per month
On average, dishwashers use 57.6 gallons of water per month.
The most common water usage per month by dishwashers is 62.71 gallons.
Dishwasher water usage ranges from 29.38 gallons to 62.71 gallons per month.
The table below shows how much water dishwashers use per month, in gallons and liters, splitting results into various usage categories.
| Water usage category | Water use per month in gallons | Water use per calendar month in liters |
| Average | 57.6 gallons | 218.05 liters |
| Most common | 62.71 gallons | 237.38 liters |
| Highest | 62.71 gallons | 237.38 liters |
| Lowest | 29.38 gallons | 111.23 liters |
This assumes 215 dishwasher cycles per year, which is close to 18 cycles per month.
How much water does a dishwasher employ per year
Per year, dishwashers use 691.24 gallons of water on boilerplate.
Overall, dishwashers employ betwixt 352.6 and 752.five gallons of water annually.
The most common yearly dishwasher water usage is 752.five gallons.
To summarize, and to include water usage in liters, the table below shows how much water dishwashers use per yr.
| Water usage category | H2o use per year in gallons | Water use per twelvemonth in liters |
| Average | 691.two gallons | 2,616.64 liters |
| Most common | 752.five gallons | 2,848.52 liters |
| Highest | 752.v gallons | 2,848.52 liters |
| Lowest | 352.6 gallons | ane,334.74 liters |
Over again, this assumes 215 cycles per year.
The figures in a higher place are based on standardized testing completed to attain ENERGY STAR certification. To achieve this certification, dishwashers must utilise less than or equal to 3.five gallons of h2o per cycle. Meaty dishwashers must use less than or equal to 3.1 gallons per cycle. Certain load capacities must also be reached. More information is available from energystar.gov, which is the primary source of dishwasher water usage information that has been compiled for this commodity.
Dishwasher h2o employ by cycle
Dishwashers use 3.22 gallons of water per cycle, on average. This can driblet to a low of 1.1 gallons on the Rinse Only cycle to a high of 7.37 gallons on the Heavy bike.
The Normal cycle tin can utilise between 81.58% and 189.47% (i.e. two.63 to 6.ane gallons) of the dishwasher's listed water usage.
Auto cycles can use 128.95% to 221% of the listed water usage, which works out to iv.15 – 7.12 gallons.
So, dishwasher water use is highly dependent on the wheel blazon.
The below goes into more particular about this. If you're not interested in how these figures were worked out, skip to the next section which puts dishwasher water use into perspective.
Dishwasher water use varies, not just by dishwasher, but also by cycle blazon and cycle phase.
Mod dishwashers have various cycle types, such as Heavy, Limited, Rinse, Fragile and Normal. An Auto bicycle type is becoming increasingly mutual.
Each of these cycle types apply a different amount of water. Limited and Rinse cycle types will employ less water than Frail, Normal and Motorcar. The Heavy cycle type uses the about amount of h2o.
The h2o amount used by each cycle type varies because each cycle goes through unlike washing stages, such every bit Pre-launder, Main wash and Rinse.
Each of these stages uses different amounts of water and they can run numeros times, depending on the cycle type.
The Rinse cycle blazon uses the least corporeality of water because it goes through the fewest stages – only ane Rinse stage.
The Heavy cycle type uses the virtually amount of water considering it goes through all washing stages, usually more than once.
Permit's demonstrate this with an example (using the same model used to give a breakup of how many watts each key dishwasher component uses).
This image shows the manufacturer provided cycle nautical chart for the Samsung DW80K5050 Series dishwasher.
Every bit you can come across, dishwasher h2o use depends on the cycle blazon due to the diverse cycle stages.
Rinse goes through the least amount of bike stages, followed by Express, which goes through 3 stages that use water.
Many other factors tin impact dishwasher h2o utilise, such equally the temperature and pressure of the h2o supply.
Withal, let'south apply the above example to become a percentage estimate of dishwasher water utilize past cycle type.
One central thing to note is that the manufacturer'due south listed water usage is not likely to line up with water usage listed by Free energy STAR. This is because dissimilar testing has been done. Manufacturers simply exam a specific cycle and identify its water employ, while Energy STAR examination procedures include several test cycles (meet exam methods on energystar.gov, here , and the DOE test method definition in 10 CFR 430, Subpart B, Appendix C, here ).
In proverb that, it looks like the water usage of the Express bike type lines up best (3.eight gallons vs iii.5 gallons from Energy STAR tests), and so let's utilize this equally the baseline.
The tabular array beneath estimates how much water dishwashers utilize compared to the h2o usage listed on the device.
| Cycle blazon | Water use (every bit a % of gallons listed) |
| Heavy | 228.95% |
| Auto | 128.95% – 221.05% |
| Normal | 81.58% – 189.47% |
| Delicate | 131.58% |
| Express | 100% |
| Rinse only | 34.21% |
Every bit yous can encounter, Heavy and Automobile cycles can use over double the amount of the listed water usage.
The water apply during the Normal cycle type tin range significantly, depending on stages used (these can be programmed manually past users in many cases). As a result, this cycle tin can use under or over the listed water usage.
The Frail cycle uses a surprising corporeality of h2o – I didn't expect this to use more than the Express wheel.
As expected, the Rinse cycle uses the least amount of h2o.
For context, the tabular array below takes the boilerplate dishwasher h2o usage effigy of 3.22 gallons and shows the estimated h2o consumption by cycle.
| Cycle type | Estimated water use based on the three.22 gallon average |
| Heavy | vii.37 gallons |
| Auto | four.fifteen – vii.12 gallons |
| Normal | 2.63 – half dozen.ten gallons |
| Frail | 4.24 gallons |
| Express | 3.22 gallons |
| Rinse Only | 1.1 gallons |
OK, now we know how much h2o a dishwasher uses by bicycle. But is it a lot?
Exercise dishwashers use a lot of water
No. Mod dishwashers do not use a lot of water. However, old dishwashers do utilise a lot of water – virtually five times more than modern dishwashers.
Also, if you're non conscientious even modern dishwashers tin can use a lot of water. If you don't fully load your dishwasher, yous'll need to run it more than often.
According to epa.gov, 1 dishwasher load per calendar week tin can be eliminated if you fully load your dishwasher every fourth dimension you lot use it.
This tin save the average family shut to 320 gallons of water per yr.
To help reply the qusetion, "Do dishwashers use a lot of water?", let's add some perspective past comparing dishwasher water usage with the amount of water other common household appliances use.
ane dishwasher cycle, which uses 3.22 gallons of water, is equivalent to:
- 1 toilet flush (or half a flush if you have a modern toilet).
- 7.8 loads of laundry (or 12.four if you utilize an old wearing apparel washer).
- Running a newer kitchen faucet for roughly i.5 to 2.5 minutes.
These figures are based on h2o consumption data available on h2o.usgs.gov.
To add some more than perspective, epa.gov (referencing usgs.gov) notes that 82 gallons of water is used every day by each American at home, on boilerplate.
With modern dishwashers using an boilerplate of 3.22 gallons of water per cycle, dishwashers can account for nearly 4% of your daily water usage.
If you accept an older, less efficient dishwasher, you can look it to account for nearly xx% of your daily water usage.
Ultimately, modernistic dishwashers do not apply a lot of h2o if you use them effectively, while older models tin use quite a lot.
Only how do dishwashers compare with hand washing?
How much h2o does a dishwasher utilize vs hand washing
Modern dishwashers use 1.64 – 3.5 gallons of water per cycle, while manus washing uses 9 – 27 gallons.
Modern dishwashers can save a lot of h2o than paw washing.
Withal, older dishwashers can use over 16 gallons of h2o per cycle. This makes the h2o savings less likely.
Related: see the FAQ, "Dishwasher vs hand washing water cost".
On average, modern dishwashers employ iii.22 gallons of water per wheel, which is equivalent to running a newer kitchen faucet for roughly one.5 to two.5 minutes.
If you can't paw wash dishes inside this fourth dimension period (I know I tin can't), then a modern dishwasher is a more efficient option in terms of water usage.
There are means that you can brand your mitt washing more than efficient. For instance, install an aerator on your faucet, scrape food off the plate before washing, fill the bowl and don't let water run continuously.
You might also exist thinking that you'll relieve on electricity also. However, it'south not as much as you might think.
Dishwashers are surprisingly efficient when it comes to electricity. This is considering, regardless of how you wash them, most electricity is required to heat h2o when washing dishes.
I go into more than detail well-nigh dishwasher energy efficiency, here. I'll use the aforementioned infographic again as information technology's relevant in this mail likewise. Also, simply to highlight, the sources of data used in this section are: usgs.gov, energystar.gov.
The following infographic compares dishwasher water usage with hand washing h2o usage. Water costs are in orange and energy costs are in white.
As you can encounter, dishwashers are more efficient in terms of both energy and water usage.
However, the range of h2o usage by modern dishwashers is actually quite significant – ranging from one.64 gallons 3.5 gallons per bicycle.
With this in mind, let's compare dishwasher water usage by make.
