LG WD-12331. Front load washer and dryer machine
since it is a washer-dryer, the lint trap is in line with the drain. you have to empty the drain basket. there's an access door on the bottom left, first take the little tube out and drain the remaining water, then open the large drain cap to the right and clean out the trap. once you're done put it all back together and it should work. you're supposed to do this every few months. It was too much for me to deal with so i ended up buying a separate dryer and just use the washer .
