Electric kettle
Also called jug kettle, coffee maker heater.
A sheathed element, a steam thermostat, and a thermal fuse. The base is a cordless connector. Leakage from element to sheath is the test that decides whether any of this goes back near water.
A donor is the dead machine. The parts below are what is still worth removing from it. “Leave it” is a part that is physically in there and should stay in there: too dangerous, too worn, or only useful as part of a repair you are not doing.
Wall power goes through a switch, a one-time thermal fuse, and often a resettable thermostat, then the element. If you remove the fuse because it is open, the element can stay on after something else has already failed. That is how the donor caught fire the first time.
Why it is in the trash while the parts are not
It will not click off, or it will not heat. The steam-stat fatigues. The thermal fuse opens if it boiled dry. The element is often still a heater.
Before you open it
Do this while it is still unplugged, cool, and not leaking. Unplug. Empty it. Do not work on it wet.
Where the dead machine usually is
- Kitchen — In the house
- Bulk trash day — Curb
Cheap and constant. Not worth buying at a thrift store.
How it comes apart
Base screws, sometimes under the foot ring. The element terminals are in the base, not in the water.
Tools: Phillips, Meter, Security bit on some bases.
Words on this page
- thermal fuse
- A one-time safety link that opens when it gets too hot and stays open. It is not a switch you can reset. Replacing it with wire removes the protection.
What to take
The table is the short version. The notes under it describe that part inside this machine, not only the general description.
| Part | Call | How many | How often | Where to look |
|---|---|---|---|---|
| Tubular heating element | Prize | 1 | usually | The floor of the jug. |
| Bimetal thermostat | Worth pulling | 1 | usually | Steam path in the handle or base. |
| Thermal fuse | Worth pulling | 1 | usually | In series, often against the element. |
| Panel switch | Worth pulling | 1 | usually | The click lever. |
| Mains cord | Worth pulling | 1 | always | Base. |
| Indicator LED | Bonus | 1 | usually | Indicator. |
Prize
1–3 kW, mains. R = V²/P.
The floor of the jug.
Insulation to the sheath must be open.
A leak to the sheath is scrap, even if it still boils.
Worth pulling
Trips near boiling when steam reaches it.
Steam path in the handle or base.
The failed one is often this. Test the click.
Fatigued is common.
One-shot, stamped.
In series, often against the element.
Open means it already protected someone.
Often open.
Mains, with the neon or LED.
The click lever.
Test.
Good.
Often a high-flex cord. Inspect it.
Base.
The connector in the base is not a universal jack.
Flex cracks at the entrance.
Bonus
With a dropping resistor, sometimes a neon on mains.
Indicator.
A neon is not an LED and will not run on 5 V.
Good.
