Just checking - there is no chance that this is from a washing machine?
Reason I ask is that powder in washing machines can clog up drains if you
put too much in.
One of my least pleasant memories is cleaning out a grid where the washing
machine (previous owner) had filled the U bend with congealed white stuff.
Thanks for responses.
It is not lamb or other meat fats.
It is a congealed, greasy, thin, near white cement type consistency,
but greasy and sticky on the hands and arms. At its worst, the rods
with claw end break free solid, then semi-solid crap.
I keep the dishwasher topped up with salt which should soften the
water. Nasty, very hard Cambridge water.
There is no feed from a washing machine into this drain.
It has a reasonable fall, but does turn a corner, maybe 45 deg as soon
6 inch after it hits the drain pipe.
I'm not the only one. A colleague across town had similar, and so did
his neighbour. The neighbour apparantly paid DynoRod ~£250 to fix !
But mine seems worse than theirs.
I think I'll try the hot caustic soda every 6 months.
The problem with modern dishwashers is that they are designed to use a very
minimum of water.
Maybe not enough to flush away residues in this case.
If a wash hand basin was also connected to the same drain it might help.
Most dishwasher detergents contain a softener.
Could be there is an obstruction in the drain.
More likely if the drain is earthenware.
Or could be missized.
Oversized is as bad as undersized.
Maybe you should get a proper chemical ion exchange water softener.
But don't drink the water.
I wonder if a liquid dishwasher detergent would help?
I'm intrigued as to what the deposit is as I've never noticed such a
thing. But maybe that's because the drain here has the sink feeding it
as well. Maybe it's something about he local water supply?
I run the dishwasher empty every few months, on max temp, with an eggcup
of caustic soda instead of detergent. I figure it flushes out any gunk
in the dishwasher pumps etc, and then flushes the drain.
Not *recommending* this - it's worked for us for a long time, but maybe
the caustic soda is doing something horrible to the dishwasher and it
will blow up tomorrow.
I don't believe that. I am currently running my
latest dishwasher on the 6' wide concrete slab
that runs the whole of the length of that part
of the back of the house, under the 6' eave
there just because I have been too lazy to install
it in the kitchen in place of the previous one.
So the drain is just lying on the ground,
so I can see that nothing congeals at all.
Work out what is congealing.
At one time I used to tip the molten fat out of
the big stainless steel pan I do the legs of lamb
in and then just put the whole thing in the bottom
of the dishwasher. That approach does end up
with a lot of fat in the drain and that does
certainly congeal there.
I don't do that anymore, wipe the pan out with
kitchen paper and that has fixed the fat problem.
I don't believe that is going to make any difference.
The solid pellets of detergent are completely dissolved
during the wash cycle and that dissolved detergent
doesn't ever congeal when its cold.
We do not have a dishwasher, we do not put fat or oils down the drain, but we
wash our clothes a lot with liquid detergent. We have the same problem. I
believe our problem is the cold and that the septic tank does not empty fluids
fast enough when there is heavy use of the washer machine, toilet, showers, etc.
(i.e., when the house is full of guests).
For some time now I have been using Muck Munchers, placing it in the
toilet bowl once a month. I have found it extremely efficient. I had the
tank emptied before starting with the product, though this is
purportedly no necessary. The money you save not having the tank emptied
more than of sets the price of the product. apart from being a customer
I have no connection to the company.

I won't say which brand of powdered dishwasher detergent it was (except tha
t it was a major brand), but I stopped buying it because I noticed it was c
lumping together, sticking to the sides of the dishwasher, and giving our d
ishes a powdery-film appearance.
When the dishwasher stopped draining, I opened up the filter to clean it ou
t and found huge clumps of the dishwasher powder all caked together...subst
antially larger than the filter-holes themselves, meaning it clumped togeth
er inside the filter itself.

some ingredients have changed due to recent federal regulations...especial
ly ingredients previously used to soften hard water).

I don't doubt you, in fact I've wondered why it doesn't happen at times-
having seen the problems you can get with liquid washing fluid in
washing machines. In the past I've noticed quite a serious build up of
'gunge' in the waste. It seems, from what I've read on the net, the grey
gunge is a mix of fat (body oil), washing fluid, and hard water
deposits. Given there will be fat in dishwasher water, while the water
is softened. unless the detergent is very different, why no gunge?
Changing back to washing powder seemed to do the trick with our washing
machine, along with convincing my wife not to use too much.
I have no dishwasher but a plumber told me some time ago that although this
detergent removes grease, the grease and the detergent can clump into what
he termed fat Burgs in sewers which are surprisingly solid, and obviously
filters and plumbing in houses have the same problem.
I've certainly not found any answer, as even hand washing greasy plates with
Fairy liquid seems to result in this congealing effect further down the

I have the same problem. Since we preprinted dishes it’s not grease buildup.
We have a septic tank so all plumbing in in basement ceiling. It is definitely
the detergent. We have been using the he’ll packs but will be going back to
liquid Same thing happened to my daughter’s house. She used powder detergent.
It filled the pipe with a sandy substance, which I assume are the filler
materials added to the detergent
Never seen it with a dishwasher but, in the past, we had problems with
liquid clothes detergent in a washing machine. The outlet and drain
became gunged up with a grey, chalky, paste.
Some research indicated it was a known issue- detergent residue, body
oil/fat (from clothes), hard water deposits, .... all mixed up. We don't
get it with power.
