Chefman Auto-Brew Logic / Programming Fault

Auto-brew (programmed start) does not work even though the time and program are set.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Incorrect AM/PM or time setting, Program not actually enabled, Control board logic error, Faulty real-time clock circuit

Safety first: Unplug before cleaning or moving the unit.

Steps:

Verify the current time and AM/PM are set correctly.
Reprogram the auto-brew time following the user manual, ensuring the program indicator icon is lit.
Test by setting the auto-brew time a few minutes ahead of the current time.

If auto-brew still fails while manual brewing works, the control board may have a logic or clock fault and may need replacement.
