We have just bought a Kelvinator Extreme Clean dishwasher. We would like to use a rinse cycle which in all other dishwashers takes 5 to 10 minutes just to rinse the dishes off before you fill the dishwasher to run a full cycle. The only cycle we can find is number 1 which runs for 90 miunutes at full heat! Please help. This is the most difficult dishwasher to use!!!!!!!
