Float valve does not rise during pressure cooking, and the cooker never indicates it is at pressure.

Safety first: Do not attempt to force the float valve up with tools while heating.

• Check liquid level: Ensure there is enough liquid in the pot for pressure cooking.
• Clean float valve: After cooling, remove the float valve and silicone cap. Clean the valve, its channel, and the cap with warm soapy water. Ensure the valve moves freely in its bore.
• Inspect silicone cap: Replace the cap if it is cracked, hardened, or missing.
• Test with water: Run a short pressure cycle with water only to confirm the float now rises.

If the float still does not rise despite adequate liquid and a clean valve, the heating system may not be generating enough steam and should be checked.
