I've had the odd sock come out the discharge hose and plug up the
drain. I thought it was just because the washer was 20 years old, but
I bought a new Kenmore and it does the same thing.

I've never had much luck with lint traps or pantyhose--just slipps off
or gets clogged up quickly.

I have had good luck with a eavestrough gutter strainer stuck into the
laundry tub drain. I take it out and clean it every few weeks. I've
never had the tub overflow since I put it in 3 years ago!!
