Timer or delayed start function does not work correctly; cooking starts immediately or not at all.

Safety first: No special hazards, but always ensure food safety when using delayed start.

Steps:

• Review the T-fal manual for the correct delayed start procedure; some programs do not allow delay.
• Reset the cooker by unplugging for several minutes.
• Test the timer with water only to confirm behavior.

If the timer still misbehaves and other functions are normal, the control board may have a firmware or clock circuit fault and may need replacement.
