Most people with mixer grinders attest that leakages are a common occurrence on this appliance. Unfortunately, users tend to ignore this issue. Sadly, it can damage the components in many ways. Mixer grinder leakage can occur due to various factors.

  • The most common cause of jar leakage is old age when your mixer grinder outlives its lifespan. When this happens, you may have to budget for a new machine to replace the old one.
  • You may also experience some minor leakage due to loose or weak blades.
  • A crack in the jar results in leakage.
  • It can also happen when the rubber gasket wears out.

You can quickly fix a leakage in your grinder if you have a set of handy tools such as the screwdriver. Here is how to fix a leakage while considering the different scenarios.

  • If loose blades cause leakage, you can tighten them with your tools, but you can call an expert to fix it if the fault is more complex.
  • First, disconnect the appliance from the electric connection and be careful when handling the blades since they may cause bruises to your hands or injury. After tightening, put a cup of water into the jar and test if the jar is leaking. If it is still leaking, contact a technician to inspect the problem.
  • For cracks in the jar, the best solution is to replace it with a new one. It may be costly, but you can always find one that suits your budget.
  • For the case of the rubber gasket, you can take the mixer grinder for repair if the warranty is still valid. However, if the warranty has expired, then you need to buy a new rubber gasket. Your technician will advise on the best option to suit your budget and needs.


2. Unsharpened blades

Even the best mixer grinder blades will lose their sharpness over some time. Once the sharpness vanishes, the quality of mixing and grinding deteriorates drastically.

However, you can quickly identify this problem if the ingredients maintain coarseness even after grinding for a long period. As a result, you may be tempted to grind continuously, leading to high energy use and more bills to pay. It can also lead to the eventual breakdown of the appliance.

Fortunately, this is solvable since you only need to sharpen the blades and restore the appliance to its normal working condition. As a matter of caution, you need to be careful since sharpening blades can lead to injuries if not handled properly.

  • Before you begin, unplug the appliance from the electric connection. Then, put some little amount of rock salt on the grinder and switch on the appliance.
  • Allow it to run for some minutes and then switch off. Clean with water and test whether the blades are now sharp. You can also use uncooked rice and try grinding for one minute. Then remove the rice, wipe off the blades using a damp and soft cloth and then test the sharpness. If the sharpness is not restored, you can buy a new set of blades.
  • It’s an easy task, and you can do it yourself. Furthermore, a manual accompanies such a purchase which you can read and follow the instructions.
  • If you’re not confident enough, you can engage the services of a professional for a quality job.


3. Tripping

As you may already know, mixer grinders are electric appliances and therefore may experience power overload. Luckily, most units in the Indian market have overload protection features to safeguard the unit from damage due to frequent power blackouts.

If your mixer grinder keeps tripping, do not freak out. It’s solvable; however, ensure you fix it asap. It may happen due to loose wiring or an overload. In the long run, it can damage your appliance if you do not put an end to it.

Tripping consumes your time as you have to turn on the power button several times before you are done with the grinding. The impact of this is visibly noticeable since it leads to unfinished or unrefined ground content.

Typically, a mixer grinder uses high power voltage, and like most electrical appliances, it has a circuit breaker. To avoid overheating, it automatically goes off. Many factors can cause tipping or power overload.

  • Overusing your grinder for a long time can cause the problem of tipping. It’s worth noting that the quality of your mixer grinder matters for it to serve you for long without experiencing wiring problems.
  • An overload can occur due to faulty wiring. It can also be due to the accumulation of dust inside the unit or grinding tough objects.
  • Poor air circulation can lead to overheating and cause the appliance to trip.

How to fix this

  • To fix this problem, ensure the wiring is properly done with no loose connections. You need to disconnect the appliance from the electric connection for your safety. Also, you must have a tester and screwdriver to disassemble the unit.
  • The next step is to open the grinder to check its wiring. If you are not sure about how it is done, you can ask a technician to open it for you.
  • Please avoid using the grinder for a long time as it will lead to overheating. When you notice overheating, switch off the grinder to allow it to cool. Keep it unattended for at least 30 minutes before using it again. When grinding, put small-sized materials and add some little water. However, don’t add a lot of water as this can spoil the recipe.
  • Grinding hot food is another contributor to tripping. Don’t be in a rush to put your hot food in the grinder. It is better to wait for it to cool before grinding. In addition, spending long hours grinding non-stop worsens the efficiency of the appliance.
  • If you’re not a qualified electrician or may not have the tools, it’s essential to call a professional to look at the unit and fix it immediately. Regular servicing can ensure your grinder stays clean all the time.
  • Also, the technician can detect a problem with the motor and consider a replacement. The technician may also recommend you change the circuit breaker switch if everything else fails to work.
  • Ensure there is enough space in the countertop, so there’s no interference with the airflow around the mixer grinder.
  • Also, there should be free space between the countertop and the appliance base to prevent overheating.

  • You can leave them overnight and assemble them in the morning. Please turn on your appliance and test whether the blades are now moving faster. If not, contact a technician for assistance.

Another scenario is whereby blades fail to rotate because there’s something underneath that’s blocking, and you can fix this by cleaning or removing the debris. Take care not to harm your fingers as the blades may be very sharp. If you are unsure how to go about this, fix it with professional help only.


6. A broken coupler

  • Start by turning the jar in an upside-down position. Then, apply some oil to the appliance’s motor coupler and leave it for a few minutes.
  • Using a pair of pliers, try twisting the coupler and see if it moves. Then leave it for a few minutes. Plug back the appliance into the electric connection and run it for at least a minute when empty.
  • It will be a good idea to put in some warm water and run for a few minutes.
  • Finish by wiping the jar with a soft and clean cloth. If the problem persists, get in touch with an expert.
