Did you soak the scrubbies really well first before you put them in?
If not, it could just be trapped air inside the scrubbies that's only now being pushed out.

Make sure nothing is clogging the impeller intake down at the bottom of the canister.
Break it down completely and try again. If that still doesn't work and you know for a fact everything is seated right, remove the pump and give that a check.
