Many homes in the 60's had 1.5" galvanized waste lines for the washer. My parents had something like that and it flooded often. I replaced theirs in the 70's.
Here is a Lake Hills home from 1960 with the old galvanized trap and standpipe, which was also flooding. At the concrete level I found a 2" cast iron hub which allowed me to use a rubber bushing to transistion to ABS.

Just a little space at the top where the washer dropped into the santee.

The pipe gets cut out, and then wrestled out of the lead packing. The packing I pry out.

New rubber bush, and a Mission coupling where the two sections of 1.5" meet on the vent.
Now it's a 2" p-trap and standpipe.

Nice space under the stairs to make the changes.

Some modern washers have a high output from the drain pump, and will flood with an 1 1/2 in. drain even if the pipes are
in excellent condition.
