Rice is overcooked or mushy. Too much water or incorrect cooking setting. Reduce water slightly next time. Select appropriate cooking mode.
Rice cooker does not start. Power cord not plugged in, inner pot not properly seated, or lid not closed. Check power connection. Ensure inner pot is correctly placed and lid is fully closed.
Unusual noise during cooking. Normal operation sound for Pressure IH (steam release, pressure adjustment). This is typically normal. If the noise is excessively loud or accompanied by other issues, contact support.
