Black stuff in the bottom of the dishwasher

Last night I opened our Whirlpool DU920PFGT4 dishwasher after it was done and found black and grey "stuff" on the bottom. I started to wipe it up and found big black chunks wedged up below the door. It didn't look like part of a gasket or rubber. None of it stuck to the dishes. It didn't smell bad (like old food). A lot of the pieces came out of an indent on the bottom of the inside of the door, but again, they were irregularly shaped and didn't seem like part of a gasket. Thanks

Re: black stuff in the bottom of the dishwasher

That black or gray stuff you're talking about is actually a combination of old food particles and soap deposits. The stuff builds up in the corners of the lower front areas of the tub and right under the inside of the door where it closes over the tub front. These areas can develop "scungy" deposits because these are areas that the dishwasher doesn't always clean and/or water remains pooled. A little routine cleaning about once a week around the bottom lip of the door and the door gasket with a damp sponge will prevent this build up. Hope this helps you.

If you have a Wet/Dry Vacuum, then you can use that to **** up any debris you see in the bottom of the Dishwasher. Make sure you remove the paper filter from the vacuum so it does not get damaged from the water in the bottom of the Dishwasher. I use the vacuum trick to clean up the muck from the pump area and it works well.

Not getting dishes clean

Hard to believe but you have to clean the dishwasher. There are various screens and baskets down in the bottom of the dishwasher. Take out the rolling bottom dish rack and you will find the first layer of filter there. Usually there is a handle on it lift or turn and lift that whole rig out and wash the basket and all the filters. There even may be a second layer of filter below that. Then check down in the the very bottom for chunks of stuff or even broken glass. Now the spinner. There is a spinning water sprayer that can also get gunk stuck inside it.. I found rice in mine. There should be a click lock or some kind of release tabs on the side of the shaft. remove that sprayer and look closely at the water jets to see if stuff is in there. run some water thru it too make sure the jets are open. lastly.. you must run the dish washer every day. if you leave them there over night you will need a jack hammer to remove the dried food. Some dried food like egg yolk will never come off in a dish washer.

Standing water in bottom of dishwasher...didn't drain.

hit the cancel drain cycle. Often times the dishwasher drain hose is not installed properly. It must be routed up as high as the dishwasher as soon as it comes out of the unit. May be also that there was a little regular soap or something that made it sudds up. vegetable oil poured into the dw tub will remove the sudds. Try to wash again after cleaning out the sudds and run it again. Thanks

Clean light flashes constanly. Won't clear out to start new cycle

I can't get the light to clear off. I can "cancel" and it goes through the drain cycle, but when done after opening the door to reload, then trying to start, it does nothing.
