Fixing Leaking Electric Kettle

<< < (2/2)

wraper:
There must be a rubber seal around the heating base which leaks. To fix it long term you will need to replace it and clean all of the calcium build-up underneath it. If you just clean it and leave the old seal, kettle will start leaking again after a few months.

Gyro:
I suspect that these days, it's a one time crimp seal around the rubbler. I've never had any success getting one apart to that level.

There is a round plastic part around the edge which holds the heater in place, IMHO looks removable.

You mean that dripping is supposed to turn off kettle and redirect voltage to ground by tripping residual-current device?

What if leakage is not actually a leakage but accumulation of a condensation caused by escaping steam from within like someone pointed out?

The normal turn off is not from the dripping water conducting current. This would be a possible failure mode to than trip the GFI.

The normal turn off is from steam condensing and this way heat a thermal sensor (bi-metal) to switch off. Without water is in kettle, the higher temperature and normal heat conduction should make it turn off too.
It does not need much condensed water to heat up the sensor enough, but it would be some. This water needs to flow off somehow and may leak out.
