Own a whirlpool dishwasher with six sense.
Kindly advise me if we can reset the timer to ONLY 30mins or 45mins as 2hours is the only time on the machine.
First time user and in booklet don't...
This machine determines the time it will take to wash depending on the load and how dirty the dishes are. It actually looks at the load in the machine and as it washes, it also checks the first and subsequent emptying of waste water, to see how soiled the water is. The machine then adjusts the duration of the wash depending on what it finds as it runs through the cycle. Consequently, you can't adjust the time. However, the 2 hours that the machine is displaying is an estimate, based on the most recent loads that it has done for you (I'm not sure, but I believe it is the average time taken for the last 10 or 20 loads). If the machine is new and hasn't built up a history of the loads you use, the estimated time to wash will be quite high (there may well be a 2 hour default estimate). This does not mean that it will necessarily take 2 hours. You will find that when you put in a load, the time to finish will be revised as the machine goes through its cycle.
Consequently, if you typically do the same sort of load time and time again, you will see that the estimated time to finish will begin to stablise around a more realistic estimate as the machine "gets a feel" for how long the load will really be likely to take.
Bottom line, just let it do the loads and trust the technology to do the best job that can be done. The time to finish will begin to change as it builds up a history and the machine is designed to use as little water and power as possible without your intervention.
