My Foodsaver vacuum won't shut off nor does it get the air completely out. I have to manually seal the bags by pushing the seal button & when I do it seems to loose some of the vacuum that it does have. I really like the unit when it works, but it's frustating when it doesn't. Hopefully you can help me solve my problem. Pat

I had to take mine apart and clean the vacuum line out. It got tiny amounts of liquid in it over time and did the same thing. Before you take it apart, try setting the adjustment screw on the back. It's for altitude but, a slight turn could get you the results you need.

Check the altitude adjustment. Also, check for food debris in the intake hole, tube or path. Check for debris on the rubber seal around the sealing strip.

This is likely happening because the unit cannot detect that a vacuum has formed, and the gaskets around the vacuum channel are the probable culprit. The Foodsaver gaskets will deform and/or dry out with time, just like in any device, but you don't necessarily have to replace them. I've tried this inexpensive solution on my own Foodsaver V2490, and it works perfectly.
Buy some food-grade silicone grease and apply it to both the upper and lower gaskets. I remove the gaskets and coat both sides with a thin layer of grease before replacing them in their respective channels. And since this grease will be absorbed and/or dry out with time, you will have to do this occasionally, so I also flip the gaskets (i.e. turn them over) whenever I apply the grease.
You can buy a 2 oz container of silicone grease at any dive store, or you can buy it over the Internet by searching for "Trident silicone grease".
This is a link where you can buy it for around $7.00:

I do not work at this dive center, but I am a scuba diver and already had some grease that I use for the numerous rubber gaskets in my gear. The 2 oz. jar will last you several years, and you will find many other uses for it around the house since the grease will last longer than a spray.
