    Default KDTM384ESS Dishwasher 1/4" of slime

    Model Number: KDTM384ESS
    Brand: KitchenAid
    Age: 1-5 years

    Hello all! I am really hoping someone can help me. I have a chronic problem with my Kitchenaid dishwasher (with the window in it). I don't know if it is the dishwasher or not it might be something else. I can thoroughly clean all this brown disgusting goop off of everything. It comes off in sheets like 1/4" thick. Inside of the rails, in the pipes, everywhere and within 4-6 weeks it is back again. I have used every dishwashing detergent in the book including Cascade with Phosphates. Tried every combination of cycles. We rinse everything, stack correctly, do not block any flow, etc, etc, etc.... The drain is working perfect and the loop is where it is supposed to be. I also do not run the dishwasher through the disposal it goes to the main sink drain. I am at my wits end with this garbage and seriously considering to just not use it anymore at all.

    HELP!!!

    Recheck your model number. Nothing comes up with that number. Read it from the tag on the machine. Click here: Appliance Parts follow the link “How to find a model number”

    I suspect the problem is with your water supply or possibly with the rinse aid you're using. With the machine empty, start a normal wash cycle. Do not use any soap. After the machine enters the wash cycle let it wash for about 90 seconds. Then open the door and look for any soap suds on the water. Any further diagnosis I'll need that model number.

    Thanks! How do I tell when it is in the wash cycle? It is very quiet and the top panel is blocked by the countertop when it is running.

    I included below what I have from Sears. I have tried without rinse agent and with using just vinegar as well. I still get the buildup. I am open that this is my water but what in the water could cause this? Should I send a water sample out for analysis? I am on public/city water.

    Can't you see it spraying water out of the spray arms through the window? Most dishwashers start with a 2 minute drain then the fill cycle and then the wash cycle. Turn off all the extras like heated wash, heated dry, or any sani-cycle.

    If you're using too much soap, that could cause it. Check if anything melted on the heating element. Water with high mineral content or salt content turns to steam and then condenses on everything. It could be a combination of your water and soap or rinse agent. If you have a soft water system you should cut the soap back to half.

    Thanks - the window is largely useless. But I can shine a flashlight in to get a general idea what is going on. Definitely not using too much soap. I fill the little cup to 1/2 or less of powdered Cascade Industrial (has phosphates). Heating element is clean and no water softener in the house. Rinse agent is just Jet dry but I used straight vinegar for around 6 months and still got the slime buildup.

    Interestingly, since the last time I cleaned it earlier in the week, instead of trying to get it to the longest cleaning cycle, I have changed it to the shortest cycle. The long cycle is near 4 hours but the short cycle is around 2 hours. With the short I cannot do a sani rinse or use the "scrubber" jets but I am still able to choose heated wash. With this the dishwasher appears to be cleaning better. I can't say for sure since it will be another 4 weeks until it builds up enough sludge to tell if that is better or not. Also while cleaning it last time I managed to break off the top small water spinner. I ordered a new part but right now that is just water coming out which seems to also be helping to clean better.

    This dishwasher just seems to me to be a piss poor design. It is just about the most expensive dishwasher you can buy but cleans so pathetically bad that you are better off washing by hand. I already lost a drain pump for it too after less than 3 years. Kitchenaid was only too happy to tell me all warranties on this POS were over.

    I can't believe that I am the only person that gets a 1/4" of slime buildup every 1-2 months.
