I need to put rods through my drain about every year or so due to
dishwasher detergent congealing and clogging the drain.
Using "Finish" (top brand ?) tablet detergent.
We rarely use the sink which drains to the same path, so it doesn't
get much "flush though".
I'm assuming when the dishwasher drains, it re-congeals when the
expelled "liquid" gets cold.

Any suggestions ?
Maybe a liquid dishwasher detergent ?

Thanks.
More likely either (a) fatty solids from the items being washed or (b) a
problem with the drainage.

I would have thought that dishwasher detergent would be most unlikely to
congeal. As Nick says, most likely to be greasy plates. Lamb fat in
particular is great at setting in drains.

Get a dog to prewash all your greasy plates and pans.
