Possible Causes
Corrupted control board firmware, Failed real-time clock (RTC) chip, Low-voltage issue on logic circuit, Button input error during programming
How to Fix / Troubleshooting
Safety first: Unplug the unit before extended handling.
- Factory reset: Consult the user manual for a factory reset procedure (often holding specific buttons while plugging in). Perform a reset to clear stored timer data.
- Reprogram clock: Set the current time again, then re-enter the auto-brew time. Ensure AM/PM is correct.
- Power cycle: Leave the coffee maker unplugged for 15 minutes to fully discharge the control board, then reconnect and test.
- Board replacement: If E12 persists and other functions work normally, the timer/RTC section of the control board is likely defective and the board should be replaced.
