It isn't the dishwasher detergent that congeals.
Same one I have used for decades now.
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).
