The timer or delayed start function does not work; the cooker starts immediately or not at all.

Safety first: No internal high-voltage work is needed for basic checks; unplug before opening the housing.

• Review instructions: Confirm the correct sequence for setting the delay time in the Binatone user manual. Many models require selecting the program before setting the timer.
• Test keypad: Check if timer-related buttons respond and change values on the display. If not, the keypad may be faulty.
• Reset cooker: Unplug for 10 minutes to reset the control board, then reprogram the clock and timer.
• PCB service: If the timer still behaves erratically, the real-time clock circuit or firmware on the PCB may be defective, and the board should be replaced.
