If it worked fine before, chances are the line needs cleaned. If this is a new washing machine it could be pumping faster than the old one. Washing machine drains and traps should all be 2" and if it's 1-1/2" this can be a chronic problem.

Yup that would be a big problem.
Is it backing up only when you are doing laundry? Is is backing up when you run anything else.
