The kettle turns itself of before reaching the boil.

If your Bosch electric kettle is leaking and stopping before reaching boiling point, there are a few steps you can take to troubleshoot the issue:

1. Check for Obvious Leaks: Examine the kettle for any visible cracks, holes, or signs of damage. Ensure that the water isn't leaking from the base or any seams. If you find any leaks, it's likely that the kettle needs to be replaced, as repairing leaks can be challenging and may compromise safety.
2. Inspect the Power Base: Examine the power base of the kettle to ensure that there are no electrical issues. Make sure the power cord is securely connected and that there are no exposed wires.
3. Check Water Level and Boil-Dry Protection: Ensure that you are filling the kettle with an appropriate amount of water. Some electric kettles have a minimum and maximum water level indicator. Additionally, many kettles are equipped with a boil-dry protection feature, which automatically turns off the kettle if it detects insufficient water. Make sure you are not accidentally triggering this safety feature.
4. Descale the Kettle: Mineral deposits from hard water can build up inside the kettle and affect its performance. Descaling the kettle can help improve efficiency and prevent issues. You can use a mixture of equal parts water and white vinegar to descale the kettle. Follow the manufacturer's instructions for descaling.
5. Contact Customer Support: If the issues persist, and your kettle is still under warranty, contact Bosch's customer support or the retailer where you purchased the kettle. They may provide guidance on troubleshooting or offer a replacement if the product is defective.
6. Consider Professional Repair: If the kettle is no longer under warranty and you cannot resolve the issues yourself, you might consider taking it to a professional appliance repair service. They can assess the problem and determine if it's worth repairing.

• Remember to prioritize safety when dealing with electrical appliances. If you are unsure about any troubleshooting steps or if the issues persist, it's always best to consult with the manufacturer or a qualified professional for assistance.

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.

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.

Our first Smart Kettle was great and worked well for years, finally died so we bought another. Right from the first boil it seemed to boil for about 2 or 3 minutes before turning off and then either didn't boil or made beeping sounds when not being used so after a couple of weeks we returned it and it was replaced. Great. But now this new one seems to boil and boil before turning off so maybe they are just faulty now. Any suggestions?

this same thing happened to me

There is no do it yourself fix for this problem. However, placing a folded cloth on top of the kettle (covering the spout) will cause it to switch off quicker, as it increases the pressure inside the kettle.

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.
