Possible Causes

Food residue around float valve, Bent float pin, Excess internal pressure due to blocked release valve, Deformed float valve seal

How to Fix / Troubleshooting

Safety first: Never force the lid open. Ensure the cooker is unplugged and allow extra time for cooling.

  • Release residual pressure: Gently move the steam release valve to the venting position using a long utensil. If no steam escapes and the float remains up, wait an additional 15–20 minutes.
  • Tap float valve: Using the handle of a spoon, gently tap the side of the float valve to dislodge any food particles.
  • Clean after opening: Once the float drops and the lid opens, remove and clean the float valve and its silicone cap thoroughly.
  • Inspect for damage: Replace the float valve or seal if bent or deformed.

If the float repeatedly sticks, replace the float valve assembly to ensure safe pressure release.
