Food is consistently undercooked even though the program completes normally.

Safety first: Unplug and cool before internal inspection.

• Verify recipe and quantity: Confirm you are using correct water ratios and not underfilling, which can affect pressure.
• Check for minor steam leaks: During a pressure cycle, observe if small amounts of steam escape around the lid or valve. If so, replace the gasket or valve.
• Inspect inner pot bottom: Ensure it is flat and clean for good heat transfer.
• Run a water boil test: Time how long it takes to reach a vigorous boil on a sauté mode. If very slow, the heater or sensor may be weak.

Persistent underheating usually requires testing and possibly replacing the bottom sensor or heating element.
