Einleitung

This guide will walk you through the following steps:

Reassembly is as simple as reversing the steps!

FIRST IMAGE:
- The red circles identify the five (5) Phillips screws.
- The green square identifies the ON/OFF Switch.
SECOND IMAGE: Remove the five (5) 3/8" Phillips screws from the base of the kettle using a #1 Phillips head screwdriver.

Using your hands, pry the base off the kettle. Open it like a clamshell: the ON/OFF switch will be the hinge point.

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.

FIRST IMAGE: Remove the power supply. Align the kettle as shown, with the handle to your right. Use the 7/32" nut driver to remove the 7/32" nut from the stud that is located clockwise from where the power supply was attached.
Use tweezers to remove the split-ring lock washer located under the nut.
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.
Use tweezers to remove the split-ring lock washer located under the nut.

Grasp the control switch with one hand and the kettle with the other.
Gently rock the control switch while simultaneously pulling it away from the bottom of the kettle.
Pull the switch completely off the kettle.

This image shows the alignment of various kettle parts.
- The yellow arrows show how the studs align with the switch brackets.
- The blue arrow shows how the steam tube aligns with the steam chamber on the switch thermostat.
