    As it turns out... it seems like it actually not. The first time we ran it seemed fine. We ran it yesterday and there was a significant amount of water left at the end of the cycle. At least an inch above the pit. We ran the cancel/drain cycle and it did drain all but the little bit that I guess is supposed to remain but it is still mildly dirty. Not really sure what to do now.

    Confirm the d/w is empty. Fill the sink up with water, pull the plug and once the water has drained out of the sink see if any water is now in the d/w.

    Tried filling up the sink and letting drain and blasting the faucut right down the drain (is the kind that pulls out at the end) and no water seems to be going into the dishwasher, aside from the water that is left standing after the draining cycle... It almost seems like when the water is attempting to be pumped out, its not all going down the drain and some being pushed back in...

    That is good, this is one common way to get dirty water into the d/w.
    Fill valve not 100% shutting off will fill the d/w, but with clean water.
    Intermittent drain out or incomplete drain out can keep a little water after each drain out and at the end of the cycle has enough left over to be above the filter and such. This is often not overly dirty water but maybe more slightly dirty.

    I believe this is the best next step. Nice thing about RC is if the part does not correct the problem the part can be sent back for a refund minus the shipping.

    So I tried replacing the pump, no dice. I also snaked the drain... nothing. Same issue, after the cycle is done, the remaining water, maybe 3-4 inches (still all below the grate so out of sight), is filthy. It does pump out all but the last say 3-4 inches of water which still seems to me like more than there should be.

    I disconnected the hose from under the sink and just let it pump out right into the sink to have a better look. The pump still runs for maybe 40-50 seconds beyond the point where water stops coming out of the drain hose during this time, the pump just kinda spashes the water around...

    any other ideas? thanks again for all your help...

    Water under the filter and in the cup is normal....even after no more is draining out.
    the remaining water, maybe 3-4 inches (still all below the grate so out of sight)
    Water above the filter would not be normal, water below is normal.....primed pump is always full of water, even when no more is coming out the drain.

    is filthy.

    Take a couple of pics so we can see the water.

    So, I should say it is "sometimes" draining all but the last bit. Here is a picture of what the water looks like always regardless of how much it drains.

    The water that remains is above the sensor if that helps even when it does drain but no matter what, the water always looks like this.

    Definetly drain water and not fill, definetly too much left after the cycle.

    See #16 Dishwasher Flowback-k0911170-00004-png

    Dishwasher Flowback-drain-hose-wpw10545278-01080196-jpg Dishwasher drain hose loop with check valve.

    Check that the check valve is working and preventing water from flowing backwards back into the d/w.
    I forgot -some- have a valve that will only allow flow in one direction.

    So I tried replacing the pump, no dice.
    Parts purchased at RC that do not help can be returned for a refund.

    Here is a photo of the trap area. I don't believe mine has a check valve?

    To clarify, the amount of water in the photo above is more then normal. although the color is consistent. Usually is drains down to the top of the reservoir / filter area.

    in the photo below is how much water if any, I would expect to see left over.

    However, the only way to get it this low is to press the cancel/drain button after the cycle is finished. Otherwise, it is never lower than the top of the reservoir.

    actually... I guess I've reached my limit for uploading photos Cant seem to delete any my old ones...

    Parts breakdown says it is suppose to be there...should be on one end or the other.

    I didn't know there was a limit!
