Question

i cant find my manual and my husband took my sentria shampooer apart to clean it.  well, he didn't put it back together. now, i don't know if i've put it back together right.  it seems to be putting the foam out right but it won't suck up the water.  i've turned the water tank off.  i've made sure of that.  could  you please give me some suggestions on what to do.  i've got people coming over for a birthday party tomorrow and i'm trying to clean the carpet.
