Were does the drain hose go to?
Does it go under a sink? If so then pull the drain hose off and check the spigot end has been cut off.
If that's fine then unscrew the spigot and check there isn't a blanking cap in here as if you have just moved and installed the washer it sounds like the waste spigot is blocked off so clear that and that should sort it.
Let me know how it goes.
