How to Fix / Troubleshooting

Safety first: Allow the cooker to depressurize fully before disassembling the float valve.

  • Disassemble float valve: Remove the small silicone cap and float pin according to the manual.
  • Clean components: Wash the float, cap, and surrounding lid area with warm soapy water. Rinse and dry thoroughly.
  • Inspect silicone cap: Check for cracks, tears, or hardening. Replace if any damage is found.
  • Reassemble correctly: Install the float valve in the correct orientation and push the silicone cap firmly onto the stem.

If leaking persists, the float valve assembly may need replacement.
