Switches off before full boil

Hello Tobi. Is it still under warranty?
If yes send it back (don't tell them about the milk thing!)
If not I sugest you bin it... You've knackered the thermostat me thinks... :-(

Yes you got it . Try cleaning the pin if not its done .

Sounds like the thermostat has gone out of calibration. If you're handy with appliance repair it might be possible to purchase (internet) and replace that part - they're usually not adjustable. Otherwise it's a new kettle.

There can be several causes. In many cases the power switch is thermo or current tripped, It is like a thermo circuit breaker.

The power switch itself may have to be changed.
The element is pulling too much current.
The thermostat may be defective.

Contact the manufacture to find out where you can buy spare parts to try. You will require the proper connectors, and crimp tools to work inside of these. Also, you will require a sound knowledge of how these appliances work, and the safe way of servicing them.

Because of the way you asked the question, I would think you are not familiar with how to service these devices. I would suggest to give the kettle to a service rep, or to purchase a new one. There are safety issues when servicing appliances.

Unfortunately the problem is in the switch mechanism, and will need to be replaced to correct the problem. My sense is it would be cheaper to replace the kettle than trying to find somebody to repair it.

I think you would only solve this problem by cleaning the thermostat contacts, or replacing the thermostat which wouldn't be worthwhile as it's likely to be cheaper to buy a new kettle.
Besides this , just getting into the kettle needs special 3 tongue screwdriver and then a certain technique to open it up without damaging the plastic parts. Im'e afraid its a throw-away world now and its not good .

this is more likley to be the switch its just a bimetallic type,when it gets hot steem on it it flicks the switch to turn the kettle off try giving it a realy good clean up inside around the switch it may just be lime scale blocking the vent hole
however normaly when the switch playes up its a new kettle

this same thing happened to me

I had a similar failure. Switch it on and the lights flicker and go out before it boils. Took it apart (Tamper Proof TORX, available from Snap-On, Canadian Tire, probably most auto parts places that also sell tools). The On-Off switch has a mechanical lock out for the lid being open and also for when it is not mounted on the base. The kettle also has three bi-metallic temperature switches. One shuts off the kettle after it has boiled long enough. The other two sit up against the element assembly adjacent to each end of the heating element.They protect against boiling an empty kettle by sensing the higher element temperture when there is no water to conduct away the heat. In the case where the lights flicker and go out, but the switch stays 'On' these are the likely culprit.
In my kettle the contacts did not line up correctly. Instead of making good contact they were only partially overlapping like a couple of the olympic rings or a couple of rings from the Audi logo. This resulted in a localized increased resistance and high heat in one of the contact holders which eventually melted the surrounding plastic. At that point the wires going to the element behaved a bit like springs which forced the contact holder further out of alignment until it all became hot enough to trigger the thermal switch.
I fixed it by bending the contact holder, which is fused into the now hardened plastic, to the optimal position and hopefully it will not generate enough heat to remelt the plastic or trip the thermal switch.
I have boiled a couple of kettlefuls; so far so good!

What ticks me off about this is that I don't mind getting 'Made In China' ****; everything comes from China anyway. But don't charge me a ridiculous amount of money and try to pretend that I am getting a superiour product. If I had paid twenty dollars or less for it I would just chuck it and get the same one again because it looks nice, pours well, doesn't burn the hands, worked OK for couple of years, etc. Instead I walk away from this feeling really ripped off. I have a house full of Braun products(shaver, kettle multiple tooth brushes) but now I won't buy any more.

Oh and if you take your kettle apart and your house burns down it is not my fault. There, now I feel better.
