It could be that you have a mechanical or electrical problem that is causing your machine to run longer. Check the water temperature. If you don't get hot enough water to your dishwasher, it will run longer as it burns energy to heat water for each cycle. See if you've added functions to your cycles.
While it depends on the cycle you choose, most dishwasher cycle times can last anywhere from 1.5 to 4 hours. The average dishwasher running time can vary based on sensor readings, how dirty your dishes are or how long it takes to heat water between cycle phases.
So if you truly believe there is a problem with your dishwasher, then you need to replace the control board below the dishwasher. Again, 3 hours is normal for a normal cycle. It can go as short as two and a half hours, or as much as three and a half hours, and there is nothing wrong.
The Delay Start feature allows you to set the Dishwasher now but have it start later. Our newer Dishwasher models call the feature Delay Hours. Most models allow the start of the Dishwasher cycle to be delayed up to 8 hours although some models can be delayed up to 12 hours.
HOW LONG IS A NORMAL CYCLE? The Normal cycle cleans dishes with 130-140℉ water and usually takes 1.5 to 2.5 hours.

On average, most dishwashers use 1,800 watts of electricity, so if you run it for an hour, that's 1.8 kWh. In the U.S., the average cost per kWh is 14 – 16 cents, so running your dishwasher for one hour, five days a week, would cost you about $1.44 per week.
The running time is affected by the water temperature, the quantity of dishes, the level of soiling and the additional functions selected. The running time will also change if the rinse aid system is switched off or on.
It's normal for a regular dishwasher cycle to last for two-hours or more, but the age and model of your dishwasher matters. The standard dishwasher cycle on modern machines tends to be longer than the typical cycle on older machines. This is because modern machines have been designed with energy efficiency in mind.
To cancel a delay:
When the delay is counting down, press the Delay pad again. The indicator light will go out, and the cycle will immediately start or resume. If you would like to download or view product literature for your appliance, please visit our Manuals and Literature page.
The reason your new dishwasher is taking 3 hours to finish a wash is likely because you have eco-mode activated! Eco-mode lowers the temperature of the water.
In short, try unplugging your dishwasher for a short while to reset it if it is running nonstop. Check for any clogs in the drain hose, spray arms, or filters if that doesn't work. Ensure that the sensors, like the float switch and door switch, are undamaged.
Electronic Timer is Faulty
A dishwasher's timer governs when power is sent to a particular function of the wash cycle. If you find your dishwasher not draining water properly or not starting as it should, it's possible the timer or its connection to the control panel has failed.
Check the Timer Motor First
Your dishwasher's cycles are controlled by a timer. It regulates everything from start to finish and switches the machine at proper intervals for filling, heating, washing, rinsing, and drying. If your appliance won't turn off, it may mean you've got a faulty timer motor.
Using more water, energy and heat for fast results, a quick wash cycle, sometimes called a 1-Hour Wash, can be completed in around an hour depending on your dishwasher model. This is a good choice for quickly cleaning up a load of lightly soiled plates, bowls or other essentials you need in a hurry.
When certain cycles and/or options are selected, a longer cycle is normal. Additional time is needed to heat the water to the proper temperature for cleaning and/or sanitizing your dishes.
The benefit of the Delay Start option is that it allows you to run your Dishwasher when its hot water demands will not conflict with those of the family. It also lets you take advantage of off peak utility rates.
HOW CAN I REDUCE THE TIME ON MY DISHWASHER? If you'd like a short cycle, choose quick wash or 1-hour wash. If your dishes are very dirty, the dishwasher sensors will allow for a longer wash cycle to ensure they're cleaned properly.
A standard dishwasher cycle typically takes 1.5 to 2.5 hours, but the exact time can vary depending on the model and the selected cycle.
Possible Problem: Clogs or Obstructions
Clogs in your self-cleaning filter, drain hose, or air vent can slow the fill and drain cycles, which means it will take your dishwasher a longer time to complete the wash cycle.
The objective was to have dishwashers clean just as well despite using less water and electricity. Manufacturers accomplished this, in part, by having their machines run longer. With less water to spray, the machines spray longer, using higher-efficiency motors and pumps.
At an unprecedented 20 minutes, the Star Speed® hot water cycle makes the Star-Sapphire® the fastest* Dishwasher available.
Typically, one load will cost you around 0.17 cents, so running your dishwasher every day for a week will end up costing you a little over a dollar. Of course, this cost can vary. A countertop dishwasher or a smaller dishwasher will typically use less electricity than a larger one.
Using your dishwasher is 'more efficient and beneficial' than washing by hand, plumber says. Running the dishwasher saves you time, but it can also save on water and keep your water bill low, experts say.
For most people, using a dishwasher is more energy-efficient than hand washing dishes because it uses less hot water. Is it cheaper to hand wash or use a dishwasher? In most households, the dishwasher uses less hot water than hand washing and is, therefore, a cheaper alternative to washing dishes by hand.
