Background and Identification
Verifying the Kettle Model Number
You can verify that your kettle is the Chef'sChoice® Model 677 Cordless Kettle by examining the sticker on the underside of the kettle (refer to the image to the right). The text on the label should read:
Cordless Electrical Kettle Model 677
Avondale, PA 19311 U.S.A.
120 V AC 60 Hz 1500 W
This same information is available on a similar label on the underside of the kettle baseplate. The baseplate has a cord that plugs into the wall unit and supports the kettle.
The device information provided here, as well as the troubleshooting and repair guides, also apply to the all-stainless steel version of the kettle, Model 677SSG.
As indicated on the label, the kettle is designed for use on a 120 Volt AC, 60 Hertz, electrical system. It uses 1500 watts of power; consequently, at peak power consumption it will draw 12.5 amps.
Basic Description of Operation
The Chef'sChoice® Model 677 Cordless Kettle works a lot like a standard tea kettle, just more efficiently. Unlike the stove burner that loses energy to the surrounding air, essentially all of the heat from the heating element in the base of the cordless kettle is directed into the water.
The block diagram to the right supports the following explanation of operation of the kettle. Components in the drawing are identified below in parentheses.
The kettle is controlled by one switch, the ON/OFF switch at the base of the kettle handle (HAND SW). This switch is controlled in two ways: manually by you; or automatically by the kettle thermostat (THERM), when the water boils. The thermostat is a bimetallic disc enclosed in the switch housing (MANUAL SWITCH UNIT). When heated, one side of the disc expands faster than the other, distorting the disc like an umbrella turned inside out in the wind. This action mechanically operates the ON/OFF switch, turning off the heating element (HEATER ELEMENT). The ON/OFF switch operates an indicating light (LAMP): when lit, it indicates that electricity is being applied to the heating element.
Two boil-dry protection switches (BOIL DRY SW1 and SW2) protect the kettle from damage in the event it is turned on with little or no water in it. Like the thermostat, these switches are bimetallic plates that turn off the heating element at the point where the kettle connects to the base (COUPLING). If these switches are activated, they can be reset by removing the kettle from the baseplate, filling it with cold water, and returning it to the baseplate.
