I'm on my second (Sent the first back) Vacuum Sealer and both will not complete the Normal VAC cycle, the machine forms a vacuum and just keeps sucking, after a while it stops but doesn't seal the bag. On Soft VAC it works, pulls a vacuum then seals the bag. I've used vacuum sealers since they first appeared. I've tried different bags and even double sealed them but Normal VAC does not complete...
