How to Fix / Troubleshooting

Safety first: Allow pressure to release naturally or use the steam release valve. Keep hands away from hot steam.

  • Disassemble float valve: After the cooker is cool and depressurized, remove the float valve pin and silicone cap from the lid.
  • Clean components: Wash the float pin, silicone cap, and surrounding lid area with warm soapy water. Remove any stuck food or starch.
  • Inspect silicone cap: Check for cracks, hardening, or deformation. Replace the cap if worn.
  • Reassemble correctly: Reinstall the float valve pin from the top and the silicone cap from underneath, ensuring a snug fit.
  • Test under pressure: Run a water test to confirm the float seals properly.

Warning: Do not operate the cooker if the float valve components are missing or damaged.
