Yes

Are you kidding?  Water spilling out and even in your basement and you're asking if something 'could have been ruined'?  You're way past that point.

Freezing water breaks things.  It probably destroyed the pump in your dish washer and any fittings near by.  

PROTIP: Don't let the next one freeze.
