Introduction
Go to step 1 ↓This guide demonstrates how to replace the control switch in your Chef'sChoice M677 tea kettle.
What you need

-
-
-
Using your hands, pry the base off the kettle.
-
Open the kettle like a clamshell; the ON/OFF switch will be the hinge point.
-
-
-
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.
-
-
-
Remove the connectors (spaded lugs) from the circuit components as shown in the second image.
-
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.

SECOND IMAGE: Roll the kettle over so the handle is now on your left. Use the 7/32" nut driver to remove the 7/32" nut from the final stud, which is now located counter-clockwise from where the power supply was attached.

OK, now I can look from the bottom. But why the switch does not keep down when I press it down I can not see or repair.
