When dishwasher is set to begin, sensor takes very long period of time. Cycles are longer than minutes indicated. Dishwasher fills with water but does not wash. Water then drains as though cycle is complete and moves to next cycle. Then the process continues. When cycle for drying is reached, much heat is given and occasionally it smells as though there is burning. A 82 minute procedure turns into hours.

Wash pump went out. Drain pump still works.
Not enough water. Improper water fill.

It could be that it takes a long time for hot water to reach the dishwasher so it fills with cold water. the control may wait for the water to warm up before advancing. Try running the water at the sink until warm before turning on the dishwasher. This may fix the problem. Some models have a water turbidity sensor and will wash until the water is clear. Excessively dirty dishes will cause extended run cycles.

There could be a few reasons for this..

Most likely the water temperature is not reaching the optimum temperature required for cycle.
The incoming water supply pressure could be lower which means it takes longer to fill.
The turbidity sensor might not be functioning properly causing the dishwasher to prolong the wash cycle.

Best to run the dishwasher empty with a Finish dishwasher cleaning kit that you can purchase from the supermarket. The instructions are written on the kit.

this should help clean dirt from all the sensors that are located in the tub.

Hope this helps.

Hi,
Yes, many dishwashers now will take at least two hours and some more depending on various things that ti checks as it is washing...
With the newer detergents and cooler water temps. the cycles are getting longer...to do the same job...

It depends on your water pressure. Mine runs a cycle in about 25 minutes, with 92 psi water pressure. Before changing all the pipes in my house, I had about 30 psi and it took about 45 minutes. The longer it takes to fill, the longer it takes to do a wash.

usaully water temperature is the major reason why a dishwasher takes longer this could be due to the water tank.To verify this open hot water valve and let it run on your hand and count the seeconds it takes to get so hot your hand has to pull out. Between 10 to 20 sec normal, 20 to 30 means dishwasher has to heat it up and this takes longer but acceptable. 30 to 60 this would really impact the time of your cycles. Now regarding the sauce pans this surprises me this could be the dishwasher internal water heater which would let be belive that water level is too low or even absent you need to let it fill up and while it is operating stop it open the door and see if water covers the heater. I do recomend that you schedule a technical service expert to verify your unit

is there any error codes showing

most likely the water valves are stuck

find out how the dishwasher is set up to drain. Pour water into dishwasher 4 or 5 gallons, see if water disappears. if so, your drain is ran wrong

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.

I have seen this several times, and all of the times it has a bad control board. usually if you take the control board out, you can see a visibly burnt spot on the back of it wher a connection has melted. Another possible slowrun time problem could be that the water coming into the dishwasher when it fills is not hot. If it isnt hot, it takes the dishwasher longer to heat the water to temp, and therfore it runs longer. Is the water coming out of your tap reasonably hot? if not you may need to turn up your water heater settings. But if nobody has messed with the water heater, or the tap where the dishwasher is attached and the problem just started then thats probably not it. Good Luck!
