Im John I will help you with the d/w problem.
How much water is left in the tub after a drain cycle please.
Is it this flapper valve you checked .
Any food particles in front when the door is open ?
Yep, that's the valve.
Not so much on obvious food particles sitting in the basin toward the front, but the tub is routinely dirty looking and when i pull the distribution header (up the back to the top) I find fair amount us food junk lodged behind.
I would try this product after you have wiped down the inside of the tub.
Its specially made to clean all the inner parts of the water system , it works really well.
You seem to have concluded that the machine is likely OK, but just having accumulated crud. Not sure I am there yet.
A consistent thing we see is food particles in the tops of our coffee mugs. I would assume food junk is pumped around duirng the wash cycle, but then it is supposed to be pumped out when the wash cycle drains. Then the rinse cycle would be clean hot water that would flush any remains away. If that is the case, how can it be present on the mug tops? Is the rinse water recycling too so if the wash cycle drains incompletely the rinse water ends up being pretty contaminated?
The only running check I have done is to see if the arms are moving (saying the pump is putting out), but have not checked to see if drain cycles are draining fully. Any recommendations on running checks I can do to see if all looks right?
Ran most of a Smart Cycle. Both prewash and wash cycles drained fully. Then a purge drained fully. Now running a rinse and waiting to see, but looking mostly normal so foar.
Have kept a periodic eye on the arms during these cycles. The larger low and center arms move for all cycles, but the little guy up on the very top has not moved for either the wash or rinse cycles. Does that indicate a problem?
That upper wash arm could be clogged up, remove the upper arm and clean it out, if the lower arms turn so should the upper.
looks like its draining ok
