Reasons Why Your Vacuum Sealer Is Not Vacuuming

These appliances, as we know, can be extremely sensitive – even the smallest, seemingly seemingly most unimportant requirements can prevent good vacuum flow and cause an obvious fault.

Interestingly, the device is not usually to blame. Most frequently, the problem is the result of user error, or other outside elements that you haven’t thought about yet.

In order to find the best solution without spending a lot of time or money, it is crucial that we approach this procedure in a precise and organized manner.

Now, let’s analyze the primary causes of your sealer’s potential improper sealing:

Wet Bag

As mentioned above, vacuum sealing is strongly dependent on a variety of requirements that must be completed, even though it may not appear like a very hard operation. You must have a dry bag, for one.

Your device must come into touch with a dry surface in order for your bags and the food they contain to be vacuum sealed effectively.

Even while it may seem paradoxical, given that the heating bar’s temperature should be able to readily ward off any surplus moisture, even that heat is unable to compensate for the moisture in the bag.

Most likely, the food you were trying to preserve got wet on the sealing end of the bag, which is why your vacuum sealer may not be sealing properly.


When you are finished placing your food into a bag, gently wipe the sealing end of the bag with a napkin or a disposable damp cloth. This will enable your appliance to properly seal, possibly resolving your issue.

Overfilled Bag

If your bag’s closure end is entirely dry, and you still find yourself asking, “Why is my vacuum sealer not vacuuming?” Chances are that your bag is most likely overfilled.

The majority of vacuum sealer bags are made to store a particular volume of food items. A proper seal won’t be created by your unit if you go beyond this limit.

This is likely the cause if everything on your machine is functioning correctly and you’re still not obtaining the desired results.


Reread the instruction manual. The highest suggested filling volume for each bag you own can normally be found there.

As an alternative, if you frequently need to freeze and preserve larger amounts, you can always think about purchasing a larger appliance or larger bags – they are widely available and come in many sizes and forms.

Broken Bag

We can safely assess the likelihood of tearing your bag now that it is both dry and sufficiently full.

The bags that come with your vacuum sealer are less brittle than the ones you can buy at the grocery store, but they are still far from unbreakable. If you utilize them often (or if they have been around the block a few times) inevitable wear and tear should be predictable.

As you can guess, even a tiny rip on the bag of your unit will prevent the creation of a vacuum seal, so please handle your accessories carefully.


You could always try patching up the holes with sellotape or any other glue, but this is not what we recommend.

First off, any adhesive you choose might not be able to seal your bags, since the material they are composed of is meant to shrink in a particular specific way. Second, utilizing these adhesives is absolutely not a long-term solution, as they cannot guarantee a flawless seal.

Although it’s irritating to waste cash on repairs or replacements, you’ll eventually have to do it.

Bad Gasket

Vacuum sealing is not possible without an effective gasket.

Your appliance’s lower lid portion is surrounded by a rubber gasket, as you are probably aware, which ensures a tight seal and permits regular operation.

It’s likely that this tiny part is either dusty or damaged if your vacuum sealer isn’t sealing properly.


The gasket should really be easy to remove. All you have to do is locate it and slowly but firmly pull it from your device’s lid. There shouldn’t be any resistance to it coming off.

Following that, you can examine it for damages. If there aren’t any and the part is simply dirty, you can wash it in clean water, let it air dry fully, and then reattach it to its original location.

On the other side, you will need to replace it if it is broken or ripped.


Temperatures that are too high can damage your appliances.

Even though your vacuum sealer is not a living being, it can become overworked.

These devices are made to run continuously, although going beyond a particular threshold can be harmful.

Your device uses heat to liquify its bag’s closing ends. While this generally produces no problems, constantly carrying out this procedure could cause the device to overheat.

A few instances of this might not cause too much damage to your device, but allowing it to happen repeatedly might drastically shorten its longevity.

Your vacuum sealer definitely needs a rest if it isn’t sealing correctly.


Put your machine on hold, give it some time to recover, and then start using it again normally.

Although overworking is not the primary cause of overheating, it is typically the most frequent.

Poor Heating Bar

Lack of heat means no sealing! Your sealer wouldn’t be able to melt the closing ends of your bags together without this component.

A little part known as a heating bar is found within every vacuum sealer and is in charge of converting the electrical power obtained from the wall outlet into useful heat.

When it fails, there are two possible outcomes: a machine that doesn’t produce any heat, or one that does so excessively.

If your sealer isn’t sealing properly, chances are that your machine is struggling to produce heat.


First, slowly disconnect your equipment and give it time to cool. Next, using a screwdriver, find the screws at the bottom of your unit and remove them.

Then, take off the top plastic case to reveal the interior of the machine, giving you easy access to the heating bar, so that you may change it if necessary.

The Benefits of Food That Is Properly Vacuum Sealed

There are numerous advantages to vacuum-sealing your food properly. If you think that the only advantage of vacuum sealing is simply to place your food in the fridge without producing mess around, it is only one of its perks! Additional advantages of a well sealed bag of food include the following:

Time Saver

Individual servings of snacks or veggies, or family-size portions of meals, should be sealed and frozen. Fix the portions you’ll need when it’s time for dinner and you’re all set!

Although some people would prefer a freshly prepared lunch, this is the greatest choice for those with a busy schedule!

Keeps Your Food Safe

Food is preserved by vacuum sealers, which stop the development of microbes or mold its track. Your food loses oxygen when vacuum sealed, and mold and bacteria cannot develop without oxygen.

Additionally, sealing food shields it from freezer burn and dryness.

Money Saver

Any food you have leftover from your meal should be vacuum-sealed soon away to save money!

By doing this, you won’t need to throw away any food and will have access to another quick lunch in the future. You won’t have to eat the same dinner several nights in a row if you just freeze it!

Final Thoughts

A broken vacuum sealer can be incredibly frustrating! You purchased this device to simplify your life rather than make it more difficult.

Fortunately, as you’ve discovered in this article, fixing the majority of vacuum sealer problems is pretty easy and quick. Most of the time, all you have to do to return things back to normal is make a small adjustment to your usage patterns, as well as double-check your bags before using them.

Please always prioritize your safety, and if you ever feel unsure or dangerous, don’t hesitate to call a professional.
