Sous vide running but the water never reaches temperature? A circulator that will not heat is usually stopped by a low water level or a safety cutoff rather than a dead element, and both are quick to check.
Here is why a sous vide stops heating and how to fix it.
This article will teach you:
- How the circulator heats water
- Why it stops heating
- What to check first
- When a part has failed
Why the Sous Vide Won’t Heat
- Water below the minimum line.
- A safety cutoff tripped by low water.
- Scale insulating the heating element.
- A failed element or control.
What You’ll Need
- White vinegar
- Your owner’s manual
How to Fix a Sous Vide That Won’t Heat
- Check the water level. Fill between the minimum and maximum lines.
- Reset it. Unplug for a minute to clear a tripped safety.
- Descale the element. Run a vinegar and water bath to remove scale.
- Confirm circulation. Make sure water flows past the element, not blocked.
Pro Tip: A sous vide will refuse to heat if the water is below the minimum fill line, since that is a safety feature to protect the element. Always check the level before assuming a fault.
When to Look a Little Deeper
Because heating ties to water and circulation, it helps to check those, and reviewing a water error, temperature that reads off, or a circulation problem can reveal the cause.
When to Call a Pro
If the water level is right, a reset does not help, and it is descaled but still will not heat, the element or control has failed, which usually means replacing the unit.
Wrapping Up
No heat is usually water level or a cutoff. Here’s the recap:
- Fill between the min and max lines.
- Reset by unplugging briefly.
- Descale the element.
- Confirm water circulates.
Check the water level first, and heating often returns. You’ve got this.
