Yes, dishwashers use the hot water heater. The dishwasher uses hot water to clean the dishes and then drains the dirty water out.
If you have a dishwasher, you’re probably wondering if it uses your hot water heater. The answer is yes, but not as much as you might think. Your dishwasher actually has its own heating element that heats up the water to clean your dishes.
However, this heating element isn’t always enough to get the water hot enough, so your dishwasher will use some of the hot water from your hot water heater.
How much hot water does a dishwasher use? It depends on the model of dishwasher and the cycle that you select.
Some models use as little as 3 gallons of hot water per cycle while others can use up to 15 gallons. The average 5-cycle dishwasher uses about 10 gallons of hot water per cycle. So, if you have a family of four and run your dishwasher once a day, you’re using about 40 gallons of hot water just for your dishes!
Fortunately, there are ways to reduce the amount of hot water your dishwasher uses. One way is to only run it when it’s full – most models have sensors that will adjust the amount of water used based on how many dishes are loaded. You can also select shorter cycles when possible – they may not get your dishes as clean but they’ll use less hot water.
Do Dishwashers Use Hot Or Cold Water
One would think that dishwashers use hot water given their name, but most actually use cold water. The water is heated by the dishwasher through a heating element. The average dishwasher uses about two to three gallons of water per cycle and can heat the water up to 140 degrees Fahrenheit.
So, if your sink is full of dirty dishes and you need to conserve some energy, feel free to load up your dishwasher with cold water – your dishes will come out just as clean!

Is Dishwasher Connected to Hot Water?
Yes, dishwashers are connected to hot water. The dishwasher uses hot water to clean the dishes and remove any food or grease from them. The water is typically between 120 and 140 degrees Fahrenheit.
Can I Run My Dishwasher If My Hot Water Heater is Broken?
If your hot water heater is broken, you may be able to run your dishwasher by using the cold water line. However, you will not be able to use the dishwasher’s heating element to dry your dishes. Additionally, your dishes may not come out as clean as they would if you were using hot water.
Conclusion
Yes, your dishwasher does use hot water from your water heater. In fact, it is the second largest user of hot water in your home, after your clothes washer. A dishwasher uses about 12 gallons of hot water per load, so if you have a family of four and run the dishwasher once a day, that’s almost 500 gallons of hot water each month!
