Peter!
The mains voltage in China is 220v which is twice the voltage that your Cuisinart was built for. It is no wonder that it is making a lot of noise and turning itself off. You need a voltage converter to reduce the voltage to the 110-120V which is that of the USA.
I hope it still works
Your blender should be about 500w. A 500w capable converter from 220v to 110v costs around
30 USD e.g. from aliexpress at the non-affiliated link below. But you should be able to get a converter cheaper in China.

They are sold on aliexpress and ebay but the price of battery and postage is not that different from the price of a second hand 3ed Gen Kindle. But then the second hand Kindle will probably need a new battery too so, I am going to get a battery from ebay.

I am a year or more too late but, as I just wrote to Lynn, these Cuisinart devices are designed to require that one push the on button down, rather than be switched on and off, as a safety feature and to protect the motor from overheating, I think. Mine can't be switched on either; I have to push.

Three months later. As far as I know that is the way they work. They are not designed to be switched on but you have to push the button down to make the blade turn. It is another safety feature. Also I think that the motor is only meant to run for 30second at a time and might overheat if left on for longer periods of time.

I have always found that by making sure that the bowl is twisted on properly and getting the alignment right (which I have many times failed to in the first instance) I have been able to get the rod to align up.

I have recently removed the safety mechanism by divesting the plunger of the sheathe that activates the rods as shown in this video where I explain how to sharpen the blade with a file

It is dangerous but in my humble opinion, no more so than my sharp kitchen knive and far less so than a car. So, in theory at least, you could take the whole thing apart and remove the electrical switch that requires the rod to be pushed down altogether.

"Downshift" I think means to shift down to a lower (i.e. bigger) gear, but on a bicycle the smaller higher gears are further "down". I was going to take you at face value but a YouTube video says "shift down to the smallest cog".

I find that it is usually because the bowl, lid, and safety sleeve thing has not been put on properly so the safety mechanism does not allow the button to turn the electricity on. As diowryir mentions above if the rod is bent then it can be more serious. I have adapted mine so that it turns on even when dangerous.

Dear Gary Sallans

It may be a manufacturing flaw as you say but bear in mind that people sell these things thinking that they are non functional (I bought one described in that way) when in fact they are fully functional, due to the over-zealous, imho, safety mechanism.

The container (which is the only part that has a “pin”), the lid which locks into the container, and the plunger attachment which locks into the lid and keeps the container’s pin pressed down to its fullest extent, all have to be correctly aligned and locked for the blades to spin.

However, if it is the safety mechanism, the motor should not hum. The only time I get that hum-but-no-spin symptom is when some food is jammed in the way of the blade.

Someone filled their machine with ice in order to unfix something that was stuck. Heat via hot water then ice might help too since the shaft and pusher are made of different types of plastic that should expand and contract to a different extent. </br> I would like to turn off the safety mechanism by adding a safety mechanism override switch so that I can take my chances disconnecting and using the oval (not the small round) pusher. True I would be able to cut my fingers off but….I can chop myself up with my brush cutter and drive my car into wall.

Thank you. I purchased a “non functioning” Cuisinart DLC 10 cheaply on auction, which turned out to have been incorrectly aligned, and was in fact fully functional. It was thanks to this article and others like it that I took the chance.
