The drain hose from my Kenmore dishwasher leading to my Kenmore garbage
disposal is getting pretty clogged. Plus the material in the hose is
starting to decompose. (The hose is translucent so I can see it in
there). And there is an odor coming from it that is really bothering my
I would like to try to unclog it, but I've never done it before.
Once I unscrew and loosen that metal clamp that holds the drain hose
onto the garbage disposal, how do I physically remove the drain hose
from the disposal? Does it just pull right off, or do I have to twist
it off? Or is there some other connector that I have to unscrew? (The
only connector I can see with a flashlight is that metal clamp around
the drain nose.)
I figured I could stick an unbent straightened coat hanger into the hose
and just try to dislodge the clogs. Is there a better way?
And most importantly: Once I unclog the hose, how do I get the hose
back onto the garbage disposal in such a way that it won't leak after I
put the clamp back on?
Get a box of TSP in the paint department of your local big-box store.
Use it instead of dish washing detergent and run the empty dishwasher a
couple of times. The gunk should be all gone. Be sure water is hot!

The chemical called tri sodium phosphate, the government
took it out of laundry detergents, years ago. And out of
dish detergent about a year ago.
It's still sold in a few paint sections of hardware
stores. Used to wash walls before painting. Be sure
to read the ingredients, some TSP is silicate, not
It greatly helped the detergent action. But, someone
decided it was harming the environment.
Recently taken out of dish washer detergents, it had been
removed from laundry detergent, years ago. Now, we all
walk around in dirty clothes. And eat off dirty dishes.
FWIW, "Someone" didn't arbitrarily decide to ban phosphates. There was an
incredibly detailed scientific analysis performed on the effects of
phosphates in wastewater. This is not a Federal ban, BTW. Just a handful
of states made the decision to ban phosphate detergents after years of
research. As a result the industry decided voluntarily to remove phosphates
from many of their products.
I don't know who's walking around with dirty clothes or eating off dirty
plates because of the removal of phosphates - certainly not me. If the
choice is a dead lake or bay full of dead fish or putting up with water
spotted dishes and perhaps grayer looking whites, I'll take the spots and
the gray every time. Cleaning up phosphate pollution costs big bucks so it
make sense not to let it get started if there are alternatives.
The issue is quite complex but I think most reasonable people can understand
the science behind the ban (mostly enacted by states with significant large
bodies of water susceptible to algae blooms caused by phosphoric
<<By the late 1960s, nearly 10,000 public lakes had been effected by
excessive nutrient enrichment by human activities (ReVelle and ReVelle
1988). Lake Erie's deteriorating condition was of particular concern, and it
had been said that it had aged 15,000 years in the last 50 (Congressional
Report HR 91-1004 April 14, 1970). The approximately 20,000 lbs of
phosphorus per day going into the lake resulted in about a 2,600 square-mile
area of the lake with no oxygen within ten feet of the bottom (Beeton 1971).
As of 1967, mats of attached algae covered Lake Erie's shoreline, and
desirable fish such as whitefish, blue pike and walleye had either severely
declined or disappeared altogether (Congressional Report HR 91-1004 April
The general feeling around the late 1960s was that the nation's lakes and
streams were getting more polluted each day, and phosphate detergents were
the primary reason. Half the phosphorus input to Lakes Erie and Ontario came
from municipal and industrial sources, of which 50% to 70% came from
detergents. Over half of the phosphorus input to the Potomac estuary also
came from detergents in municipal and industrial effluents (Congressional
Report HR 91-1004 April 14, 1970). It was generally agreed that detergents
accounted for about 50% of the wastewater phosphorus nationwide (Hammond
1971). There was a growing public consensus that in order to save lakes
(like Lake Erie), phosphates must be banned from detergents.
The scientific community made the first real effort to understand the
eutrophication process and problem. In April 1965 the National Academy of
Sciences (NAS) and National Research Council (NRC) appointed a Planning
Committee on Eutrophication in recognition of growing public concern over
eutrophication of lakes, streams and estuaries. This committee recommended
an international symposium, which was held at the University of Wisconsin on
June 11-15, 1967 and attended by almost 600 persons representing the U.S.
and 11 foreign countries. In addition to the NAS and NRC, the symposium was
sponsored by the US Atomic Energy Commission, the U.S. Dept. of Interior,
the National Science Foundation, the Office of Naval Research and the U.S.
Dept. of the Navy. Proceedings were published in Eutrophication: Causes,
Consequences, Correctives in 1969 by the NAS.>>
So that "someone" turned out to be closer to 600 "someones" all with
scientific backgrounds who decided that phosphates were causing real harm to
People tend to forget what some of our lakes and waterways used to look
like. Having lived near Lake Erie and the Chesapeake Bay I can say that
things have improved drastically as a result of the attention paid to
pollutants like phosphates. You can now swim in Lake Erie without
encountering huge mats of phosphate enhanced green slime.
Same here. I liver on the bank of Bow river, one of famous trout fishing
water. Banning that chemical made a difference for sure.
Once I watched president George Bush floating by with a fishing guide
casting a line.
It's another case that if you see the damage caused with your own eyes, you
have a very different opinion of the issue. People living in areas without
large bodies of water have probably never seen a foamed-up shoreline or huge
mats of algae floating in the water.
Phospates have a negative effect on tourism, cost a lot of money for states
like Maryland and New York to clean up and were being dumped into bays,
lakes and rivers in enormous quantities. It's easy to think "What could my
little dishwasher hurt?" but you have to remember to multiply that by the
thousands of people running a dishwasher or washing machine every day.
As for your observations about the Bow River, they are quite correct:
<<The significant improvements observed in the lower Bow, particularly in
the last decade, are directly related to improvements to Banff.s sewage
treatment facility. The extreme coliform concentrations observed in the
early years of the study period (1970s-1980s) have virtually disappeared.
Increasing phosphorus trends, which began before 1989, have significantly
dropped off and average concentrations have been reduced.>>
Your government at work. New formula of the dish detergent no longer
contains phosphate so the lack of it may be adding to your problems.
Be sure you get real TSP and not some substitute with the same name.
There is a good chance that if you go to sears.com and then navigate
to their service,support, parts area you can look up your model
dishwasher. Once you find it there is almost always an exploded view
of it showing all the parts. You might be able to tell on that picture
how the drain hose connects. I'm guessing it uses a simply wire clamp
to keep it tight. I don't think you can just "pull it off" without
using pliers to loosen the clamp and move it down off the nipple
Pliers are probably not the right tool to loosen the OP's hose clamp since
he said "once I unscrew...that metal clamp".
Typically a screw driver or nut driver/socket is used for the type of hose
clamp I suspect he has.
Does it look like this?

The ones I've seen are made of wire - think of the old heater hose
clamps on cars, thick spring wire. I was differentiating between the
screw on type he indicated he saw on the disposal end with what I
think he'd see on the water pump end.
Pliers are the correct tool to use on what I referred to as "wire
clamps". But no, for the other clamp, on the disposal end, which he
obviously has seen, it would take a screwdriver or nutdrivdrer.
Google "wire clamp". Just because it's made of wire doesn't make it a "wire
clamp", especially since there really is something specifically known as a
"wire clamp". Whether it's the screw on type or this type, it's still a
Keep in mind that the OP admitted to being a newbie, so we should make sure
we keep the terms we use accurate.
Of course, I was going to loosen the clamp, slide it down the hose,
before trying to disconnect the hose. I was just wondering if then the
hose would just twist off the disposal or if there was some other
"gotcha" I didn't know about.
