Lid will not open after cooking; float valve appears stuck in the up position even after cooling.

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

• Check pressure indicator: Wait until the float valve drops fully. If it remains up after 30–60 minutes, proceed carefully.
• Gently tap lid: Using a wooden spoon, gently tap around the float valve to free any stuck residue.
• Use a long tool: If the design allows, gently nudge the float valve from the top with a non-metal tool to see if it drops. Do not pry the lid.
• Once open, disassemble and thoroughly clean the float valve, its channel, and gasket.
• If the float frequently sticks, replace the float valve assembly and gasket.
