as the machine fills it increases the force of the water several times than the pressure that is coming in from main house supply within four minutes the water level reachs the overflo, then i open drain valve you can tell by sound of the tub is empty as you hear it trying to suck the water up,for good washing n rinsing the drain valve must be close to increaese the water pressure when the valve is close it also controls the speed of basket by slowing it down a bit ,i leave valve open beginning of cycle for prerinse an rasing the temp. of dishs an tub for obout a minute at this time the basket spins very fast,then close valve an you start to hear the suction of water jets an basket starts to slow down a bit at that time I add the detergent threw the dispenser at the top of the lid after four minutes I open drain n close again for first rinse n again same process for second rinse than I ad jet dry threw the same disp. for two minutes an shut water off first than drain an open lid right away an the basket spin for to more minutes on its own ,when it stops dishs are almost dry carl from the kaiser fraser car club is going to make me a copy of the use n care book I had no book when igot the machine it took me a wlile to understand the concept of this machine an how it worked but its been fun an I love this dishwasher I also love your youngstown dishwasher would love to get my paws on one of those im going to try to make a video but first I have to kidknap a ten year old to show me how its hard teaching an old dog new tricks lol! thank god for peter because he post all the pictures for me well hope this helped you , lou
