FoodSaver Vacuums - Recent Questions, Troubleshooting & Support

Hair dryer. Remove both tray inserts and dry thoroughly, paying special attention to the sensor area in the center of the upper tray.

Question edited for clarity. Question moved from Laundry Dryers. How on earth did you manage to plug in a 110 volt plug into a 220 volt socket? There is no service manual for these units. Return it to them for warranty repair. There is one video that may help. https://www.google.com/search?q=foodsaver+v3840%2C+service+manual

I am having the same problem.. any answers??

I kicked you out of computers, off topic there. it needs service.

Have you checked to see if the element is intact? if not, http://www.elementsandmore.com/

Perhaps the bags you are using are not suitable. If they are too thin it will not vacuum air out.

Pull out the long rubber piece on the top, clean any debris, replace firmly.

Sounds like the foam seals are leaking. Go to their website to get replacement parts.

Does it try to vacuum but never flattens the bag? Make sure the bag you are using is completely sealed on the opposite end. Otherwise, the seal on the sealer is probably allowing air to leak into the sealer. If it has a foam sealer, I've found it sometimes helps to run the foam sealer under water, squeeze out the excess water, reinsert the foam sealer (make sure it is seated all the way) and then try again to seal the bag.

That could be a bad foam seal not completing suction, A piece of debris that got sucked into vacuum line and or in pump, or in some cases a crack in a elbow or pump housing.

wow when I ran my food business I seemed the only one that could get this thing to seal right every night , Im gonna say it was because I wasn't in a big hurry , these machines work great but there not fast it takes sometimes 5/10 minutes to get a good seal on them , and you cant overload them either , when it comes to these less is more , makes for a easier time using them allow the food to stop about two inches from top edge of bag , and wipe any loose food from the sealing surface (inside) as this will affect the seal as well

press release on top cover , I had someone use mine 1ce and they pressed "seal" with no bag in machine it did exactly that it stuck closed, tight too !! one touch of release button on top cover and it popped open

The heater bar is too hot. Allow it to cool for a while before resuming sealing.

I experienced the same problem yesterday. I somehow stumbled across the fix. I had the unit unplugged and used my thumbs to forcefully pull down the door (didn't use the handle). Once I discovered I could force it down with my thumbs, I plugged it back in while holding the door down and it seemed to reset itself and now works perfectly! Good luck!
