Which brands of electric tea kettle last the longest and are the easiest to use?

try vinegar neat white or brown its less corrosive than the branded descalers which do work quicker i admit but my kettle started to leak
because of these strong cleaners now i use vinegar its cheap.
place 500 ml to 1 litre in kettle switch on just warm vinegar and switch off leave in for 30 minutes swilling round empty and you can keep in a bottle and repeat every month if you wish or use in cleaning solution if you don't want to waste it look on internet 1,000 ways to use vinegar.
wash kettle with copious amounts of water inside and then use kettle cleaned and sparkling

I've seen mixed results across the internet on this one. From personal experience, for some reason, my glass teapot left some sort of stain on my ceramic stovetop. It also took longer to heat. I then went out and bought a simple metal one and have been pretty satisfied. If cosmetics are a concern, it's not too difficult a step to pour the water into your teapot after the fact, right?

anon.nick-20625 was right.

Opened the bottom of the kettle, not the charging base, using the three odd screws.

Found the white trip switch, which was a white line in the socket which connects the kettle to the charging base. Pressed it with a screwdriver and it came out more. Tested the kettle, works!

Your tea kettle has a thermal fuse inside that more that likely got over heated, it happens all the time with irons, coffee makers, most small appliances that are electric. you have to take the bottom off to find it and replace it. does it have an indicator lamp?

Mark,
what brand is this kettle. is it a tea pot?

If the kettle was bought with a credit card, then you are in business because the statement will back up the purchase and the store would have a record and would have to comply. But! if the gift was bought with cash it will be difficult to prove, still I would bring it back to the store and ask for the manager, the last thing they want is bad publicity, especially when you show the condition of the electric tea kettle and what it could mean for the store's reputation, you may be surprised with the results.

Vinegar is very good at removing scaly deposits. Heat white/clear vinegar just as you would normally heat the water for your tea. After heating the vinegar, pour out and rinse thoroughly with water. If there are still deposits after this first attempt, use vinegar once again. Once you are satisfied that all the deposits have been removed, heat water in the tea pot 2-3 times to remove any smell or taste from the vinegar (before using for tea).

It is possible the reed valve broke.

Thanks for the offer, but i no longer require help. I found out that the model tea kettle of mine is no longer made and they do not have filters for it.
