Why newer dishwashers run for an alarmingly long time - washing dishes in river in restaurant kitchen

It’s counter-intuitive.
The new dishwasher tends to run much longer than the old machine, but the advertising for the new dishwasher is to use less electricity and water.
The "normal" cycle is extended to more than two hours
The old machine is about an hour.
Judging from the information on Internet dishwashers and home appliance websites, these longer runs have made people wonder if something is wrong with their new machine.
And, if they're working properly, how can newer technologies be so much slower?
After we bought a new dishwasher, I was curious about the running time of the dishwasher (
Refrigerator)
Replace a 12-year-
Old unit with loud noise.
I checked the explanation on the Energy Star website about the long run time. The U. S. -
The US-based Energy Star program released a new standard that came into effect on January.
2012, require less water and energy for the dishwasher.
Specifically, the title of energy star (
Because it can help promote sales, what manufacturers are eager)
No more than 4 machines must be used for normal circulation. 25 gallons (About 16 liters)
Suppose a machine runs about four times a week, water per cycle and electricity at no more than 295 KW hours a year.
The water entering the dishwasher is expected to be hot enough and does not need to be heated with the machine.
Manufacturers have several years to redesign their machines.
A dishwasher summit was held on October 2010 to discuss details.
The purpose is to keep the dishwasher clean while using less water and electricity.
Manufacturers do this by having their machines run longer.
Spray with less water, longer spray time for the machine, use higher-
Efficiency motor and pump.
I'm not sure exactly how this works.
Details seem to be trade secrets.
In addition to the longer running time, better energy efficiency seems to include improving the way the spray arm works, the design of the disc rack, despite running two or three times the length of the motor in one cycle, but it uses less power than the old motor.
Manufacturers have recognized that it is difficult to sell more concepts.
Bosch is a company that makes more advanced products.
End dishwashers made this comment in the material submitted to Energy Star: "With the running time, cleaning performance can be improved and energy usage can be reduced.
However, consumers associate running time with energy use, and when faced with long runs, they usually choose to wash less loads by hand.
"It's hard for me to understand that, too.
The dishwasher runs twice as long as it used to, but consumes less water and electricity.
Like magic.
But it is still possible to return to the good times of the past with a new machine.
The Energy Star standard is based on the "normal" cycle.
Nothing can stop manufacturers from including shorter cycles, thus consuming more water and electricity to produce more aggressive sprays.
For example, on our machine, there is a quick cycle of washing dishes in less than an hour.
I can hear the difference.
The machine is louder and sounds more like spraying more water with more force.

This is the repeated wisdom on the energy-saving website: wash the dishes and use more water and energy (
For heating water)than a modern-day dishwasher.
In 2004, a study on this was published in the journal Family energy. “ . . .
We convinced 113 people from seven European countries to do the dishwashing experiment.
We compared their use of water and energy and the level of cleanliness they achieved, as well as the consumption generated by two energy-efficient dishwashers.
In order to reduce the variability of test conditions, we have most test subjects wash dishes in a lab at the University of Bonn.
For the test subjects, we chose tourists who have not lived in Bonn or Germany for a long time to ensure that they did not act in Germany.
To ensure that we have a correct understanding of consumer behavior in a specific country, in laboratories in France, Italy, Spain, re-testing with the same equipment, and the UK.
"This study confirms that, compared with humans
The Era dishwasher usually does better while using less water and energy. ---
People who save energy are-rinsing.
Don't waste all the water to rinse your plate before putting in the dishwasher. Just scrape.
If you can't help yourself, rinse with at least cold water instead of warm water or hot water.
Energy Star even has a sign of no flushing.
But many dishwasher maintenance workers say washing can help prevent machine failure.
They said they would rinse before loading their own machine.
All the garbage can hold things up.
There is a discussion about this in angieslist. com.
Our dishwasher's manual lists the schedule for cleaning the filter so that it is not blocked.
It also said that before starting the machine, we should run the hot water on the tap near the dishwasher for a while.
In this way, hot water will enter the machine immediately. ---
