My grinder is not similar to the ones in the instructions. It's the same model, but it looks different inside. The blades are fasten with something that looks like a plastic nut on top. I´ve tried pulling on the blades, but it doesen´t seem to work. I´ve also tried to undo the nut, my tools are causing damage to the nut.

Do anyone know if this is a nut, or pulling harder is the solution? And if so, do anyone know if it is a right or left threaded nut (normal or lynx)?

My problem with the grinder is that the blades wont turn. The motor is working, but of some reason, either the rotor in the motor or the blade assy is stuck.

Thanks!

I think I've "burnt out the motor," or whatever the technical term is, on my burr coffee grinder, by plugging it in to a 240v plug.

Is the solution replacing the motor, the wiring, or what? I assume many appliances operate the same when having and issue like this, so any advice from similar kitchen appliances are welcome!

Thank you for your time!

I finally opened up the coffee grinder to examine the issue (btw, my grinder is an OXO one that doesn't have a guide yet on fixit.)

I think I found the problem(see images where components have burn damage)..but I have no idea what I'm looking at.

I'm quite keen to fix it. Especially since I emailed OXO for help and they said "just buy a new one."

Here’s some images of the board there are no discernible burn out issues as far as my untrained eye can see even the popped fuse looks normal 🤷🏻

I saw comments saying to remove 4 screws or clips, or remove the paper label to expose the slot in the bottom of the shaft. They don't all necessarily have those.

It does have what looks like two #2 Phillips screws retaining the base. They have about 40 years of rust on them, but it looks like that's all that retains the base.

So depending on the vintage of your grinder, the parts may not be exactly the same. Luckily, these devices are simple, with little more than the motor, blade, switch, and body. You may just need to do a little more work to figure out how yours comes apart.

I only came looking to see what I'm getting myself into before I break something. I kind of assumed that the blade was pressed on, rather than screwed on. I'm glad I looked, before I broke it, trying to pull the blade. :)

I plugged my grinder to wrong outlet (the correct one is 120v-60hz) and then somthing burned, do you know if the grinder has some fuse for such cases or that my grinder is dead? Do you know how to fix this?

Now when I try to make coffee, it stops pouring water too soon. I tried resetting it. I tried to unplug it, hold the Lungo button, and plug it back in. The Corto light blinks a few times. But when I try to make an espresso cup of coffee, and it still stops too soon.
