Repairing an electric kettle that doesn't always auto shut off

<< < (3/4) > >>

Hogwild:
I'll give it a try, thanks. I like to keep anything and everything I can out of the landfill. Of course, with an item like this, it needs to have reliable auto-shutoff to be safe, so that is my overriding goal.

Hogwild:
Before I get back to working on the kettle, does anyone know where that spring goes?

GLouie:
The spring looks like one of two on the lid hinge on my kettle.

I am confused by the steam tube talk. I took mine apart once, and did not see any connection between the electric mechanism and the water chamber. There is a tube opening for a water level gauge. I confess I didn't look very carefully at the time.

Most kettles have a tube running from the top of the boiling chamber down to the bimetallic strip at the on/off switch at the base. When the water boils, steam flows down the tube, heats up the bimetallic strip, and turns off the kettle.

It pretty complicated - you can search for Strix Ltd. patents on this.  https://patents.google.com/patent/EP2741641B1/en
I thought it was pressure switch, because steam (heat) requires a net flow- but this explains why they get plugged.

OP I noticed the one electrical connection to the stub going to the heating element looks heat oxidized like it's a poor connection that heats up a bit. Check that crimp spade.
Ali has some switch assemblies but a little dodgy looking https://www.aliexpress.com/item/1005005307163145.html
No idea which spring or where it came from, the one you lost.
