Coffee maker powers on but will not start brewing when the brew button is pressed.

Safety first: Unplug the unit before inspecting switches or internal parts.

• Check basic conditions: Ensure the water reservoir is installed and filled, the carafe is in place, and the lid and basket are fully closed.
• Try different modes: Attempt both regular and strong brew (if available). If one mode works and the other does not, the issue is likely in the control logic rather than the button hardware.
• Clean around buttons: Wipe the control panel with a slightly damp cloth. Sticky residue can cause buttons to stick or not register. Do not allow moisture to enter the panel.
• Test safety switches: Open and close the lid and remove/reinsert the basket while listening for clicks from the internal switches. A missing click may indicate a failed switch.

If the brew button never responds, the button switch or control board may need replacement.
