water weighs 10lb to the gallon ( engilish measurement-calculate amount for us gallon)
so get your self a jug and place it on the scales empty adjust the scales to zero
fill the jug with a measured amount of water (example 1 pint will weigh 1.25lbs
then set the scales to the reading of 1.25lbs
to check the scales accuracy you can add extra water to the jug (say 4 pints ) and the scale should read 5lb

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 had this problem recently; I think my kettle have accidentally been turned on empty. The kettle has a safety for that, described as follows in the manual:
"The kettle is fitted with a safety device, which protects against overheating should the appliance be operated with insufficient water. If this occurs the kettle will stop heating. Switch 'Off' at the power
point and allow kettle to cool before refilling. The safety device will automatically reset when the kettle has cooled down."

Then they go on to tell you that there is an additional thermal cut-out, and if that is tripped, you have to send it back to Breville for servicing. However, it might not be that bad-- it wasn't in my case.

The heating connector and control is made by Otter, here's information that I was able to find about it on their website (Otter A1 and CS7 control and connector-- I think the kettle actually uses a CS4 connector, but the thermal cut out isn't described on that data sheet):
"The A1 control integrates to 360° cordless plug with element
dry boil protection. Two bimetals spring loaded against the
element surface make a fast response during dry boil. One
bimetal disconnects the live side of the electric circuit and the
other disconnects the neutral. A latch out function prevents
dry boil cycling. This automatically resets when the kettle or
jug is lifted from the cordless base."

So what does this mean to you? If you look at the bottom of the kettle jug, there is a circular indentation that slots into the base. There are two white plastic things which I believe are part of the "latch out" described above in Otter's documentation. If you see them sticking out, they may be stuck in position instead of resetting as they should. Use something like a pencil eraser to gently poke them so they unstick, then put the jug back on the base. That should cause them to retract, and at that point your kettle should work again.

Some types of kettles use a separate power base to heat up the kettle jug. If this is the case with yours, turn the jug upside down and look. Also look at the parts on the base that touch the kettle jug contacts. If you can see the electrical contacts; mine were built on spiral rings for differing temperatures; try cleaning them with Brasso and a Q-tip (cotton swab) wiping the contacts several times to remove any tarnish and then use clean swabs to remove all traces of Brasso metal cleaner. Fill the kettle jug up to the maximum fill line and put the boiler on the maximum setting... boiling water. If the water doesn't boil... you have a more serious problem. Buy a new boiler as it isn't worth having someone fix it. Mine worked like new after I cleaned the contacts. Never immerse the jug contacts in water!!!

You are correct in suspecting the element. You need a Torx bit to undo the screws.

Yes I would say its had its time now
