Dishwasher runs for a long time

Sometimes a dishwasher will run for hours especially new ones. Newer dishwashers use very little water but run much longer. There are some things you can do to shorten the time. Turn off the options. These extras will add time to the cycle. Sani rinse, Heavy wash, Hi temp, Pot and pans, Tough cycle. If you have a normal load of dirty dishes it’s unnecessary to add options. A normal load without extras can take 3 or 4 hours alone.

"Fisher washer stays on clen for over 3 hours" ???
I think you mean the "Dishwasher stays in the clean cycle for over 3 hours", right? First question is "What cycle?" If it's the Pots and Pans cycle, or "Pro-wash cycle" , or "Normal cycle with extra wash heat or sani-rinse options selected, then yes, this is normal! A Normal cycle (without added heat) will take about 2 hours. And a short or quick or 1-hour cycle will take less.

You can also reset the breaker that supplies power to it and see if that helps. This sounds like the control panel is going out.

Similar Kenmore Dishwasher 665.18664000. Time saver and Quick rinse were the only programs that would run. I pressed "high temp scrub" then "air dry" then "high temp scrub" then "air dry" and the machine went into a diagnostic mode and counted down from 10 while running a series of tests. After about 10 minutes and various test cycles the machine reset and the "normal wash" light had come back on. If this doesn't work then you may have a problem with the controller which other threads have mentioned replacing yourself for about $120.

Open and close the door to make sure the door latch is securely fastened

Hi-Temp Wash, Hi-Temp Rinse, or Sanitize options.
Some models have options that may require a water heating delay, such as Hi-Temp Wash, Hi-Temp Rinse, or Sanitize. Additional time may be required to heat the water to the proper temperature. The dishwasher will continue to circulate water during this heating delay but the timer will not advance until the proper temperature is reached

Hi,

This may sound strange but that is a normal cycle time for today's dishwashers. They use much less water and the water is 'recycled' within the filtration system in the pump.

By reusing and filtering this water they save on heating energy and water consumption. The motors are not as powerful so they use less power even when running longer. Many machines will alternate the wash between the upper and lower arms, this type uses much less water and energy but again the trade off is long cycle times.

If you were to select a heavy or pots and pan cycle with hi temperature wash and a sani rinse your times can be up to 4 hours in some machines today.

The reason behind these savings are mostly due to the energy standards that the appliance manufactures have to abide by today.

I know this may not have been what you wanted to hear but it is how they work today.

Make sure the sani cycle is not selected, or pots and pans, also with the dry cycle most will take about 2 hours, if your dishes are not that dirty use the short cycle. Be sure your water is at least 130 F. Run hot water at faucet before starting the machine.

Try this solution first
Push the Hi-temp and then push the Sani-rinse. Go back and forth multiple times on these two buttons. I found that after a handfull of pushes that a "1" came up on the display. I continued to keep rotating the two buttons and then a "2" came up on the display and the dishwater started it's "drain" phase. I then hit cancel to clear and then I selected the cycle I wanted. The washer started up just as normal at this point.

press back and forth between hi-tempwash and sani rinse several times to get all lights to come on if not then press sani rinse and heated dry back and forth several times. one of though combos will start the test mode

bellman, on this model I believe you can clear the fault by pressing high temp scrub--air dry--high temp scrub--air dry in that order. Your normal cycle on this dishwasher is approx 97 minutes without the thermal holds, (pauses to heat the water to proper temps.) So of course it's going to go over 97 minutes. This is for heavy soil. Light soil, approx 89 minutes. Some models have a soil sensor, some don't. If the sensor is out of specs..it could add to long wash times. The heater may in fact be the problem, he needs to check it. The heater runs through the nuetral side of the door switch so you want to make sure the switch is closing and the dishwasher is level and secure. He also wants to check out the resistance of the thermistor, should read 48 to 52K ohms at aprox. 75 degrees. Catriver..post back.
