we had aplastic tub washer that liked odors and lint with odors:
if the lint fibers are built up between the inner perforated tub which
holds clothes and the outer water holding tub, you'll want to bleach
them. if you have a plastic instead of stainless tub it may seem to
hold more odors. turn on an exhaust fan and follow washer instructions,

run a full load of water, agitate to mix in the bleach, and let it
soak.
