MDC4650AWW Portable Dishwasher
We've had a similar problem. A banshee screaming noise that's makes the
skin crawl. Since our machine is well out of warranty I took the
insides apart and found only a few cherry pits. (Lesson learned, always
scrape your dishes before loading.) We covered out ears for a few
minutes and the bad, bad noise went away. But the noise came back, it
didn't stay away.. So here's what I found with more tinkering.
1. Problem: Small hard things can get lodged in the food mill/grinder
assembly at the bottom of the dishwasher tub. It's there to cut up the
big chus of organic matter I presume.Today I found a thin piece of
plastic about an 1" long that got caught and was resisting being
ground(even though we know resistance is futile) by the grinder thing.
Anyway, I took the offending piece out, put it back together and the
machine is working fine. I have a hunch that the first instance may
have been one of those stray cherry pits that broke up enough to get
2. Solution: take apart inside assemblies to get down to the "foodmill"
like thingie and see if there's something hard organic or unorganic
causing the noise. Discard. Put back together and hope that solves it.
(It did for our machine)
3. What's needed? Good knees or a decent knee pad and a few simple tools as follows:
A. 1- medium flat blade screwdriver
B. 2- TORX screwdrivers, # T-15 and T-20, or equivalent bits for a portable electric drill/screwdriver.
C. Small pair of regular pliers or simialr tool.
D. Muttering under your breath like Fred Flintstone, or not.
Take out the water jet assembly. It is held by a clip at the back and
top. Use the screwdriver to pry the tabs away from the clips, then pull
the assembly out at the bottom where it connects. It's a simple slide
in/out fit. The bottom whirlygig water jet is fastened with a threaded
cap that can be removed with the pliers. (BTW, this can get clogged
with gunk. while you have it of check for gunk. Then, keeping track,
remove the remaining hardware with the TORX #T-20 screwdriver until you
get to a round black piece. The black piece has to come off before you
can remove the piece with the filter and grinding screen. Use the #T-15
bit for removal of the black piece. Then remove the rest 'till you see
a "blade". Hopefully in that process, whatever was causing "the noise"
will fall out and you can discard it. Observe how gross it is in there,
shudder, and begin the process in reverse.
I do have some pictures of the process in stages if you want. E-mail me

Well, that's it. I hope it helps someone.
Have a Blessed New Year!
