Display shows “ERR5” and the timer or clock functions do not operate correctly.

Safety first: Unplug the coffee maker before performing any extended resets.

• Factory reset: Consult the user manual for the specific button combination to reset the clock and timer settings (often holding the clock and power buttons together). Perform the reset and reprogram the time.
• Power isolation: Unplug the unit for at least 30 minutes to fully discharge internal components, then plug back in and set the clock again.
• Avoid power strips: Plug the coffee maker directly into a wall outlet instead of a power strip with other high‑load appliances to reduce electrical noise and surges.
• Persistent error: If ERR5 remains and the timer cannot be set, the control board’s clock circuit is likely damaged. Replacement of the main PCB is required and should be done by a professional.
