Possible Causes
Damaged or hardened float valve silicone gasket, Debris trapped under float seal, Bent float pin, Incorrect float valve installation
How to Fix / Troubleshooting
Safety first: Keep clear of hot steam. Allow the cooker to cool and depressurize before disassembling the float valve.
- Disassemble float valve: Remove the small silicone cap or nut under the lid that holds the float pin. Slide the pin out.
- Clean components: Wash the pin and silicone gasket with warm soapy water. Remove any food particles or starch.
- Inspect gasket: Check for cracks, flattening, or hardening. Replace with a new Cosori float valve gasket if worn.
- Reassemble correctly: Install the pin from the top and secure the gasket or nut from below, ensuring free up‑and‑down movement.
- Test under pressure: Run a water test to confirm the leak is resolved.
