Why does my sous vide stick react slowly after I add cold food?

A temperature dip after adding cold food is normal, but the bath should recover within a reasonable time if the setup is correct. This model’s temperature control is accurate to 1 °C, so a slow recovery usually points to too much food at once, a very large water volume or poor circulation. If the unit cannot recover at all, or if it switches off while trying to reheat, stop using it.

1. Check how much cold food was added. Large, dense portions can lower the bath temperature quickly.
2. Look at the water level and circulation space. If the container is overcrowded, reduce the load and allow more space around each bag.
3. Confirm the appliance is still set to the correct temperature and has not been interrupted by a timer or protection signal.
4. Wait and observe whether the temperature climbs back steadily. If it does, the unit is likely coping normally with the heat loss.
5. If the temperature stays low for an extended period, or the appliance becomes hot without recovering, stop using it.

What the result means

• If the bath recovers slowly but steadily, the load was probably heavy rather than faulty.
• If one bag cools the bath dramatically every time, cook in smaller batches.
• If the appliance cannot recover in a simple setup, there may be a performance fault.

When to stop using it

Stop using the sous vide stick if it cannot recover temperature in normal use, if it overheats, or if it behaves unpredictably after food is added. If the issue remains unresolved or safe use is uncertain, contact the retailer or store where the product was purchased.
