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 ?
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.
So would I. I'm under the impression that dishwasher "detergent" is
pretty caustic stuff . You certainly don't want to hand wash your
dishes using dishwasher detergent...
We need a description of the stuff that is blocking the drain.
Washing machine powder has been mentioned that clogs the pipes with a
hard but crumbly residue. Fat is fat thick softish stuff with not
Any drain that regularly needs to be rodded has a fault or is having
stuff down it that shouldn't go down it, like animal fats. "Fault"
would normally be not enough fall so solids don't get carried by the
water flow or too much fall so the water flows away too quickly
leaving the soilds behind.
Yeah, I've ever noticed dishwasher detergent ever doing that.
Fat does sound more likely, though I'd be a bit surprised if fat in the
dishwasher water did it? I thought it was from people pouring fat down
sink, or from the hand wash water?
Fat can certainly be a problem though. A while after moving into this
house the drain outside the kitchen blocked a bit downstream of the U
bend. (the drain turned 90 degrees as well right after it.)
Eventually cleared it with a drain cleaning attachment on a pressure
washer. Great big lumps of fat floated down from it - the drain must
have been at least 50% blocked with it I reckon

I rinse everything before putting in the dishwasher but had to have drain lines

I never get that effect with mine and I do eat quite a bit of rice.
The rice ends up in the pocket thing in the filter where its completely
trivial to knock out into the bin, with 3 completely different dishwasher
models from 3 completely different manufacturers.
Hell of a lot easier to do that than to rinse everything
that goes into the dishwasher. Stupid waste of time.
All I ever do is scrape off the biggest stuff like say
chop bones into the bin before the plate goes into
I have had 3 completely different dishwasher models but the almost identical
appearance of the inside suggests that they have all been made in the same
factory with just the badge on the front being different
