This is most likely caused by a lack of venting on either your washing machine drain or sink.
The gurgling noise you hear is actually air getting drawn through the water in the sinks trap as the washing machine water drains past the sink drain.
Both the sink and washing machine should be checked for venting issues by a licensed plumber.

It just depends on the way your bath/sinks are plumbed vs the amount of vent air available. If you system is designed with adequate air venting the "gurgle" will be reduced or eliminated.
drain line is partially clogged.
It will eat away the surface of your sink. www.pamperingplumber.com
Gurgle is a noun (a gurgle) and a verb (to gurgle).
Probably because the line is still at least partially clogged.
Because the washing machine drains down the same main drain and it's suction as it goes by is trying to suck the water out of the under sink U trap.
Drink more water then you can pour out of the sink.
By properly sizing the vent by fixture units and developed lengh and pitching it up from the fixture it serves
I enjoyed listening to the waterfall's gurgle.
