2 Blunt Blades

When used for a long time, it is natural for the blades to lose their sharpness. To sharpen them, you will
have some rock salt into the jar and spin the unit for a few minutes. Alternatively, you can also use rods or
sharpening stones instead of rock salt. Ensure that the lid is closed tightly before starting the mixer grinder.
The rock salt will sharpen the blades of the mixer and will make it as good as new.
3 Tripping

The reset button present under the mixer grinder will trip if you continuously use the appliance for long hours
or grind hot items. It is highly recommended that you don’t use your mixer grinder for too long and wait till the
food is cooled down before grinding it. If the tripping happens due to excessive heat, you need to reset the red
switch located on the undersurface of the mixer grinder. Unplug the mixer grinder, remove the jar, and look
under the appliance to find the switch. This should prevent your mixer grinder from tripping.
4 Broken Coupler
Couplers connect the base of the blender to the jar. They will break or wear after using them for a few. If you
frequently blend frozen fruits and vegetables at high speeds, it will damage the coupler. You can not repair a
broken blender. The only option is to replace it. You need to be very cautious while replacing the blender as
the blades are very sharp. It is not such a bad idea to seek the help of a professional.

5 Stuck Buttons
The buttons in your mixer grinder will get stuck if you spill food or liquid on them. They enter the space between
the buttons and make them defective. To solve this, you need to wipe the buttons with a clean wet cloth. Some
models come with an option where you can remove the face of the buttons. This makes it very easy and
convenient for cleaning purposes.
6 Slow Moving Blades
When food particles get clogged between the blades, they cause the blades to move slowly. This can be
very frustrating because it takes up a lot of time for grinding. If that is the case, you have to remove the blade
assembly and clean it. Soak the blades in warm water and scrub the sides and edges of the blades. Now,
assemble and fit them into the mixer grinder. The blades should rotate faster.
7 Jar Getting Stuck

If the bearings in the jar are damaged, the jar will get stuck on the unit. Corrosion in blades occurs when there
is a leakage in the blades. The food or liquid that is ground will enter into the bearings and cause corrosion. To
rectify this, you need to remove the jar and pour a few drops of oil around the motor coupler. After allowing it
for a few minutes, you have to twist the motor coupler using pliers. Now, fix the jar in the mixer grinder and run
it for two minutes. Then, fill the jar till it reaches half and allow it to run for a minute. Wipe the jar with a clean
dry cloth. After doing this, you should be able to fix and unfix the jar seamlessly.
8 Overload Problem

The mixer grinder will shut off automatically if there is an overload. The overloading of a mixer grinder happens
due to three reasons,
9 Low Capacity Motor

When the motors are not powerful and you run them for a long time, the motor will get heated and the unit will
overload. Run the unit for short durations with frequent gaps to prevent this.
10 Air Circulation
Air circulation will cool the mixer grinder and prevent it from overheating. Some models will have extensions
at specific points or at the edges on its lower surface. This will facilitate air circulation. Alternatively, you can
place the unit on a stand with holes.
11 Thick Materials
When you put too much food into the jar or when the food is very thick, the motor will get heated and overload.
To prevent this, put small quantities of food into the jar. If the food is very thick, add a small quantity of water
to soften them.
