Bought a Nutribullet from US and accidentally ran it with 220v supply. Later bought a step down transformer and tried, it’s not powering on, what could have gone wrong? Disassembled the unit and the motor windings etc look fine, is there a fuse or a reset? Update (07/02/2017) Is there a wiring circuit diagram for Nutribullet? The motor windings are rated 120v, so it would not run on 230v, this would require re-winding of the motor to match the voltage. Are the power boards sold separately?
Use a multimeter and test for continuity on the motor and other wiring. See if you can locate a possible fuse (that should have blown first).
Chethan Anand, it is very likely the power board has been damaged. Replace it. You can likely use a 220V supply with it. I believe that’s what the board is with “some circuit with couple of transistors, capacitors, resistors and diodes.” Hope this helps!
