Its a multi-variable problem. Time, temperature, initial concentration of germs, tolerable final concentration, and if spores must also be killed(requires more extreme conditions), must all be factored. 49 to 60 C ( 120 to 140 °F) is considered cool enough to promote bacteria growth in a dish washer. Water can be pasteurized by heating to 65˚C/149˚F. Pasteurized is not as effective as total sterilization.

∙ 12y agoBacteria that are harmful to humans are killed by temperatures of 140 °F (60 °C).
Other bacteria can survive, even thrive at much higher temperatures.
According to the accepted standard for making water potable, it must be boiled, which I believe is 212 degrees at sea level and it must be boiled for 10 minutes.

Water temperature for washing dishes?
Dishwasher should only connect to the hot water line. Here is no additional heater for the water so tt should be the same temperature of the water boiler of the house.
Why is the temperature needed to freeze ocean water lower than the temperature needed to freeze a surface of a fresh water lake?
The ocean is larger than a lake. Therefore, being larger it can absorb more heat. That is why a lower temperature is needed to freeze it.
What does it take for water to freeze?
For ultrapure water a temperature of 0 oC is needed.
Why is the temperature needed to freeze the ocean water lower than the temperature needed to freeze the surface of a freshwater lake?
Dissolved salts in water contribute to a decrease of the freezing point.

Do all dishwasher sanitize the dishes?
No. A dishwasher will not sanitize dishes unless the option is turned on. A normal cycle will use very hot water to wash and it’s good enough. A sanitary cycle heats water to 170 degrees. You should have a good reason to use this cycle.
How hot does the water have to be to sanitize dishes and laundry and how long does that temperature have to be maintained?
The wash water temperature in a dishwasher should be 140oF to 160oF to avoid baking the food on the dishes. The rinse water needs to be 82oC (180oF) for 60 seconds.
What should the wash-water temperature be when washing dishes in a dishwasher?
Between 60 and 71˚C for washing, and 82 or higher for at least ten seconds to sanitize. You can also sanitize at low temp if you use chemicals (e.g. 100ppm chlorine).
What temperature should water be to sanitize laundry?
185
Why does a dishwasher make a banging sound?

What are the process used to manually clean and sanitize dishes?
Bleach. Read the instructions on the bottle. I think it's a 1/4 cup of bleach to a gallon of water.
What information is needed to calculate the amount of energy needed to heat of volume of water to some temperature?
You need the amount of water, the temperature of the water, and the desired temperature.
How do you sanitize a sponge?
SOAK IT IN BLEACH WATER
Does temperature always need for vapourisition of water?
Yes, a high temperature is always needed for vaporization of water.
