Display shows a water-related warning (e.g., "H2O" or "Add Water") and the cooker will not start or stops heating.

Safety first: Always cook with the inner pot in place and with adequate liquid as specified in the Aroma manual.

• Check water level: Ensure there is at least the minimum required water or liquid for the selected program. Add more liquid and restart.
• Inspect inner pot: Confirm you are using the original Aroma inner pot. Check that the bottom is flat and clean. Replace the pot if it is warped or heavily scratched.
• Clean heating plate: Wipe the heating plate to remove any residue that could interfere with heat transfer.
• Re-seat pot: Rotate the inner pot slightly while pressing it down to ensure full contact with the heating plate.
• Test with water only: Add 2–3 cups of water and run a basic cycle. If the warning still appears quickly, the bottom sensor or control logic may be overly sensitive and require service.
