Common problems and fixes
Weak seals
Moisture or food on the seal area. Wipe the bag rim dry and use the moist setting for wet food.
Air leaks back in
A failed seal or a punctured bag. Double-seal the ends and check bags for holes.
Liquid sucked into the machine
Seal wet food with the moist mode, freeze liquids first, or use a chamber sealer.
Bags cost too much
Buy rolls and cut to size, and reuse bags that held dry food after washing.

The winner is insideRepair or replace?
Repair when the problem is a single worn part, a cleaning issue or a settings mistake — most vacuum sealers problems are. Replace when the core structure, coating or motor is failing, when spare parts are unavailable, or when repair costs approach the price of a new unit. Safety faults — damaged cords, cracked housings, electrical smells — always mean stop using the item and replace it.
Frequently asked questions
How much longer does vacuum-sealed food last?
Several times longer than ordinary storage, in the fridge and especially the freezer — but it does not make food last forever.
Can I seal liquids?
Yes, with care: freeze liquids first, use the moist mode, or use a chamber sealer.
Are bags reusable?
Bags that held dry food can be washed and reused. Bags that held raw meat should not be reused.
