There are several reasons for your chopper’s blades to get stuck. Please see if one of the following will solve the problem.
Check that blades are attached properly
If the blades are not attached correctly, they might wobble inside the bowl or get stuck while running. Unplug your appliance before checking the blades and do not handle the them with your bare hands.
Remove and reattach the blades by turning the shaft clockwise and counter-clockwise. Tighten the blade shaft until it holds.
For more information on installing chopper blades, consult your user manual. If you’re having trouble finding your manual, download it here using your product’s model number.
Avoid overloading the bowl
Overfilling the bowl might cause your chopper’s blades to get stuck. Do not exceed the MAX limit marked on the bowl.
Place it on an even surface
Your appliance should be operated on even surfaces. Make sure that you have placed it on a flat, even surface before using it.
