KitchenAid Start Circuit / Safety Interlock Not Engaging

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

Safety Warning

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

Brew button switch failure, Lid or carafe safety switch open, Control board logic fault, Brew basket not fully inserted

How to Fix / Troubleshooting

Check all interlocks:

Ensure the water reservoir is full and properly seated.
Verify the carafe is fully on the warming plate.
Confirm the top lid and brew basket are fully closed and latched.

Try a reset:

Unplug the unit for 5 minutes, then plug back in and attempt to start a brew cycle.

Inspect buttons:

Press the brew button several times; if it feels loose, stuck, or does not click, the internal switch may be faulty.

If all mechanical interlocks are correct and the unit still will not start, the brew button switch or control board may need replacement.
