Quoting the manual: 6lbr5132eq1
"MAGIC CLEAN* LINT FILTER
Your washer has a MAGIC CLEAN lint filter at the
bottom of the basket. Wash and rinse water flow
over the filter during agitation, separating the lint
from the water. The lint spins out of the system
during the spin part of the cycle.
If your washer drains into a tub, remove any lint
collected in the tub or strainer."
