It is also possible the drain line is too small diameter. I had a friend,
one time. Washing machine would back up the drain and pour all over the
floor. Turns out the PVC drain line was too small dimaeter. The cure turned
out to be replace all that PVC with larger size.

Rooting out the drain does not necessarily say it is clear for the
full diameter all that distance, unless the head of the rooter is
full drain diameter. A laundry tub is the quick and easy way to slow
down the input to the sewer. A full rodding of the drain line with a
full diameter head on the rooter is the only other solution.
