Why does my sous vide stick stop during cooking?

If the stick stops part-way through cooking, the most likely causes are low water, blocked circulation or a safety cut-out. Do not continue using it if the appliance has been running dry, has been splashed at the electrical parts, or if you cannot confirm the water level is safe.

1. Check the water level immediately. The appliance has boil-dry protection and a water level indicator, so a low bath may cause it to stop. The expected result is that the water remains above the minimum line. If it has dropped too low, refill carefully before any further use.
2. Look for anything obstructing circulation around the stick, such as a crowded container wall or bag pressing against the unit. The expected result is free water movement around the heating section. If the flow is blocked, reposition the food and appliance.
3. Check whether the room is very warm or the appliance has been running for a long period. Even a silent circulator can pause or cut out if conditions are not ideal. The expected result is that the unit restarts once it has cooled if a temporary protection has activated.
4. Inspect the display for any unusual indication and confirm the timer is still set as intended. The expected result is the timer continuing to count down. If the timer has ended, the appliance may have shut off normally.
5. If it stops again with a correct water level and clear circulation, unplug the unit and stop using it. Contact the retailer or store where it was purchased for further advice.

Do not keep resetting the appliance repeatedly if it stops without an obvious cause. If there is any sign of overheating, unusual smell or damage, stop using it at once.
