When your washing machine drains or empties the water, it pushes the water out at high volume using its drain pump. When gurgling at sinks or toilets occur, this usually means the shared waste pipe is partially blocked. The blocked waste pipe does not allow the water from the washer to pump out fast enough..
Consequently, what does it mean when your sink gurgles?

Secondly, why is my bathroom sink drain gurgling?

This buildup can cause the water to drain slowly.
