Washing machine backs up into Kitchen sink.

My washing machine and kitchen sink are on opposite sides of the same wall. They share inflow which splits underneath the sink. They apparently share a drain, as the sink has been filling up as the washing machine empties. I don't know when it started, but a couple nights ago, it nearly overflowed the sink. The only thing that I have tried is to turn on the garbage disposal. I thought that might help if the problem is airflow. Instead the water backed up the washing machine drain pipe and overflowed onto the floor. Where do I go from here?

Clogged drain lines are common with kitchen sinks as grease and oils solidify and stick to the pipe. It will probably be easiest for you to snake the drain line from the kitchen side as the washer should have a trap that will be difficult to get past.

If your kitchen sink has a garbage disposer, quit using it.
