Re: the washing cycle takes 2 hours to complete
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.

"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.
Make sure that the water inlet pressure is good and there is no restriction ,
Now it is normal that the wash cycle is long as the dishes are put into and set to be done overnight.
But it will be good to clarify if the ECO wash takes so long as 31/2 hours, which could be fine with a high level wash.
Call LG Dealer to confirm as the set is new.
THAT IS NOT NORMAL!!!!!!! A normal wash and dry cycle will take approx. 2 hours in length including drying cycle.
You should see that water has been present in the machine within the first 2 minutes of the start of the wash cycle, you should also be able to hear the water entering the wash tub.
The fill valve or water supply seems to be the issue, if the water doesn't enter the tub then the controller won't proceed witht the wash cycle. Double check your water supply tube / hose to make sure there is water present at the connection to the dishwasher.
GOOD LUCK !
The water temp thermostat is to blame or the water is not heating.Basically what happens is the washer fills with cold water and starts to wash and heat at the same time.Once the water reaches a certain temperature it moves onto the next stage of the wash program.If the water is not heating or the thermostat is not working the programmer wont get the signal to move on.Hope this helps.
Most probable failure is the thermostat that senses the water temperature. The way to test it to run a cycle with all the options turned off. It it completes the cycle normally, then it's the thermostat (part number 154290204), if it still takes hours, then it's a board/timer
momrules, it could vary depending on the water entering the dishwasher. On a heavy cycle normal time is about 85 minutes not including thermal holds ( pauses that heat the water). On a normal wash, 68 to 75 minutes not including thermal holds. If the water entering the dishwasher is not at least 120 to 140 degrees the dishwasher will pause in cycles to heat the water before advancing. So 120 minutes is not unrealistic. The heaters in the dishwasher are low wattage and will only heat the water approx. 2 degrees every 5 minutes. Catriver.
sounds like a long time. sounds like it will wear out your dishes before it ever cleans them. check the manual for cycle times. could be a bad logic board, too. this happens most often when units are new. talk to the service center for the unit since its new. they will be able to get right to the problem or send a repairman under warranty. new units do fail. good luck mark
