Probably blocked on the intake pipework. You'll need to get the Saniflo out, clean out all the build up from the inside and try again. It is probably an idea to try and clean the pipes as well.
Not really advisable to use Mr.Muscle or other drain cleaners on the Saniflo range as it can eat the seals.
