Food Saver bags don't work with the VP112S, as far as I can tell. (I have the "non-s" VP-112 and it doesn't use them.) The VacmasterFresh site and the first few vendor descriptions I looked at only mention using chamber vacuum bags. The waffling/channels on the FS bags gets in the way of a proper seal.
1 hour ago, PositiveMD said:The issue seems to be that after the timer finishes, I don't hear any air being let back into the chamber. The machine just stops running and the seal time starts. It makes me think that I perhaps installed the black seal pad on the lid and the bottom gasket incorrectly, but as far as I can tell they can only be installed one way.
The machine will seal after the vacuum timer has completed its cycle; air only comes back into the chamber after the seal cycle has finished. If it sealed the bag after air had re-entered the chamber, there'd be air in the bag. Do you hear the air coming back into the chamber when the sealer's done?
