1 day to go (then sale of the dishwasher i am looking at is over & my wife is done with me).
so yesterday i changed the water inlet valve. do not believe there was any change in how my diswasher worked. ($30 wasted but oh well).
i have the following details and perhaps it will help a bit more.
Not sure how much water is to be coming in but here is what i have figured out.
There are the following cycles of washing and for each cycle, the dishwasher does not fill all the way (to the max) for any of the cycles. i would say only about 50% of the water comes in. is this normal for each of the cycles or should the water fill until the float rises lifting the switch and turning off the water inlet valve. i tried turning the timing dial all the way around so that the dishwasher would continue filling. (basically giving it 2x the amount of time to fill the dishwasher). in this case, the float rose, activating the switch and turning off the water inlet vlave. (for some reason when i did this though some water came out the bottom of the dishwasher where the float rod comes through. So here are the runs and some info.
Pots & pans wash: only bottom arm runs.
Normal wash: only bottom arm runs.
Light wash 1 (there are 4 different times the unit will fill with water): bottom arm runs and then the top arm runs for a bit. This is where it gets odd, as soon as the top arm starts the drain pump cuts in at the same time and so the top arm wash does not occur very long.
Light wash 2: Bottom arm, top1,bot,top2,bot,top3,bot,top4,bot drain.
Light wash 3: Bottom arm, top1,bot,top2,bot,top3,drain.
Light wash 4: Bottom arm, top1,bot,drain
Drying.
So after running the dishwasher, using an all in one puck with the red ball detergent, and the dishwasher was not overly full, and not having the full amount of water in the dishwasher for each cycle, (not sure if this is required for each one or just certain ones), my dishes came our fairly dirty and there was food gunk on the front door as well. (i did not run the dry cycle.
so i ran it a second time with cascade granualar in both the open door and trap door using pots & pans cycle again. Again the dishes came out dirty.
i use finish or jet dry rinse aide.
my only 2 things i could think of were that there is not enough water in the machine for all or certain cycles, now given that i changed the water inlet valve the only things i could think of were either there is a restriction after the water inlet valve preventing water to come in as fast as it should, or the water line to the water inlet valve is restricted somehow and so not enough water is getting in to the dishwasher in the allotted time.
the other thing i thought could be shot is the timer.
also, how can you tell if the impeller is no longer any good, and if an impeller wears out does it reduce the water pressure resulting in dirty water...
thanks.
