Common problems and fixes
Water evaporates on long cooks
Cover the container. A lid, cling film or even ping-pong balls cut evaporation dramatically.
Bags float
Air trapped in the bag. Re-seal with the displacement method, or weigh the bag down.
Food tastes flat
Sous vide preserves moisture but adds no flavour. Season well and sear hard afterward — the sear is where flavour comes from.
Temperature drifts
Too large a bath for the circulator, or a draughty spot. Insulate the container and size the bath to the machine.

The winner is insideRepair or replace?
Repair when the problem is a single worn part, a cleaning issue or a settings mistake — most sous vide machines 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
Is sous vide safe?
Yes, at the right time and temperature for the food, with fresh ingredients and proper chilling afterward.
Do I need a vacuum sealer?
A zip bag with the water-displacement method works for most cooks. A sealer helps for long cooks.
Why sear after sous vide?
Sous vide cooks evenly but does not brown. A fast, hot sear adds flavour and texture.
