    • Now that you have removed the bottom from the kettle, identify all of the parts. The ORANGE arrows point to the posts for mounting the control circuit components. The RED arrows point to the following parts:

    • A: The power supply.

    • B: The two boil-dry protection switches, one on either side of the central black ring.

    • C: The power coupling. This fits into the baseplate when you place the kettle on it.

    • D: The thermostat. This is a little metal ring, half hidden by the switch cover.

    • E: The manual ON/OFF switch.

    • F: The indicator light.

    • G: The steam chamber. This heats the thermostat, which turns off the kettle automatically.

    • Take note of how the wires connect to the components to aid reassembly.

    • Remove the connectors (spaded lugs) from the circuit components as shown in the second image.

    • DO NOT pull on the wires, as you might pull them out of the connectors.

    • You should be able to remove each connector easily by hand. Pinch the lug between your fingers and pull in the direction of the attached wire.

    • If necessary, use needle-nose pliers to grasp the lug shank firmly. Gently pull the lug in the direction of the attached wire.

    • Gently bend the disconnected wires back and out of the work area.

    • Using a 7/32" nut driver, remove the hex nut that secures the power supply to the base of the kettle.

    • Using a pair of tweezers, remove the split-ring lock washer located under the nut. (It may be hard to see in low light.)

    • Using your hands, grasp the wire that is still connected to the power supply. Carefully lift the power supply off the threaded stud to which it was coupled.

    • At this point you will have removed the following parts from the kettle:

    • Five (5) screws.

    • The kettle base.

    • One (1) 7/32'' hex nut.

    • One (1) 7/32" split-ring lock washer.

    • One (1) power supply unit.

I had a Kettle like this. A little different internally. One of the problems was the center power pin had got so hot it had melted the plastic. Cant really fix that. So it hit the recycle can. Will not buy this type again.

The photographs and schematic were very helpful, but the problem was not with the Power Supply; the on-off switch lit up. I needed to remove the two other nuts at the yellow arrows and look more closely at the Boil Dry Protection Switches. I removed and replaced the metal plates and noticed that two white plastic pieces swung out into the space around the Power Coupling. Had I reset something? Regardless, after reconnecting wires and reattaching nuts and screws, the pot is back to working order. Thank you so much for posting this Fix It!
