Auto-brew (programmed start) does not start at the set time, but manual brewing works.

Safety first: No internal hazards for programming, but unplug before any disassembly.

• Verify clock: Ensure the current time is set correctly, including AM/PM.
• Reprogram auto-brew: Clear existing programs and set a new auto-brew time following the user manual exactly. Confirm the auto indicator icon is lit.
• Test short interval: Set the auto-brew for 5–10 minutes ahead and observe whether it starts.
• Check power stability: If the unit loses power overnight, the program will not run. Ensure it remains plugged in.

If auto-brew consistently fails while manual brew works, the timer function on the control board may be defective.
