hidden inside the large black hose that leaves the bottom of the outer tub.
place the drainage hose into a empty bowl then lower to the floor this allows the water to drain out by gravity. when stopped tip the machine up 45 degrees and support it while you remove the large spring clamp on the bottom of the wash tub with a pair of water pump pliers.clean out then reassemble hoses, put half a kettle of water in the drum test joint for leaks .
