Washing machine without lint filter does not pump
Many modern washing machines do not have a lint filter, but that does not mean that you can not catch all sorts of things in the pump of such a machine (especially bra straps, wire pieces, toothpicks ...). Then simply unscrew the machine at the back (unplug it first). The pump is usually at the bottom (logical) and the rubber parts are relatively easy to disassemble.
Just fish everything that has accumulated (I've learned that as a teenager in a household with notorious trouser pockets-full-lassers ;-))
