Food is consistently undercooked or overcooked compared to the selected Toshiba program (e.g., rice too hard or too soft).

Safety: Allow the cooker to cool before internal inspection.

• 1. Verify correct pot and settings: Use only the original Toshiba inner pot and confirm you are selecting the correct program and water-to-food ratio from the manual.
• 2. Clean sensors and heater: Remove burnt-on residue from the heater plate and ensure the bottom of the pot is clean and flat.
• 3. Compare with water test: Run a plain water boil test on a standard program. If the cooker fails to reach a vigorous boil or boils excessively on low settings, sensors or control board may be miscalibrated.
• 4. Sensor replacement: If other symptoms (like E1/E2) occasionally appear, replace the relevant NTC sensors. Persistent cooking inaccuracy may require main PCB replacement.

Do not modify internal components to change cooking behavior; this can compromise safety and void warranty.
