Everyone enjoys making shakes with their favorite blender. However, no machine is without fault, including blenders. They can start to leak, and that’s something you definitely don’t want to happen. But if you’re using your blender daily to make shakes and smoothies, you may face this issue soon. So, why do blenders leak?

Blenders usually leak because of the rubber gasket (also called the o-ring) that is located at the bottom of the blender housing, under the blade assembly. These gaskets start to wear over time. Since they’re expendable parts, it’s completely normal for them to wear and cause the blenders to leak.

However, this may not be the only reason for your blender to leak. It’s very common nowadays to just throw away perfectly repairable things instead of fixing them. When it comes to blenders, throwing them away may be a mistake. Most leaks are fixable, and it’d be irresponsible and needlessly expensive to buy a new blender. Keep reading to find out all the possible reasons behind the leak you’re witnessing and how to fix those leaks. Let’s get started!

What Causes A Blender To Leak?

As we’ve already mentioned, most leaks are caused by the rubber gasket wear and tear. This is completely normal, as this is an expendable, replaceable part of your blender. It’s completely expected for it to wear out with time.

If you’ve identified that your leak is coming from the bottom of the blender, the most likely cause for this is the gasket.

Another reason behind your blender’s leak may be hidden in the glass. If your gasket is fine (assuming you’ve checked), and your blender is still leaking, then there may be a crack in the glass.

If the leak is not coming from the bottom but rather from the top, then it’s definitely not the gasket. It’s most likely a crack in the glass.

Sometimes, but very rarely, the cause for the leak may be a badly screwed blade. If there’s too much wiggle room between the blade and the bottom of the blender, the leak may come through that.

If it’s not any of these things, then it’d be best to take your blender to the shop as fixing the leak may be out of your hands.

How Do You Fix A Leaky Blender?

The first thing you want to do while fixing a leak of any sort is to take the blender apart. This is naturally under the condition that you’ve already unplugged it. Do not try to disassemble any piece of electronic equipment or machine while it’s still plugged in.

When fixing a worn-down gasket, you need to disassemble the housing from the blender jar (under the blade mechanism) and take out the rubber gasket.

There will most likely be a leak in this rubber ring, and to fix it, you just need to buy another ring and replace the old one. These are usually pretty cheap, and it’s the simplest way to fix the leak.

However, if your leak is coming from a crack in the glass, then you need to replace the jar.

This usually happens if you drop your blender or somehow hit it.

If your blender has a guarantee, then you should contact the shop where you purchased it and take it there. The shop will most likely give you a new blender, and if not, they’ll point you in the direction where you can get a new jar.

You can usually get a new jar from the brand itself, and most likely for free.

Other Reasons For A Faulty Blender

Faulty blades can also be a problem for the blenders. If you turned the blender on, but the blades turn too slowly, then something may be clogging the blade area.

Once again, the way to fix this is by taking the whole blender apart and cleaning everything with a brush. The most common cause behind this problem is a build-up of food in the blade area.

If you don’t want to disassemble your blender, you can also try soaking it in detergent and letting it do the work for you.

Another way to fix this is by adding white grease or WD-40. Make sure not to put it in the area where you’ll be adding your food.

If none of this works, it’d be best to take the whole blender to the shop and let the professionals take care of it.

Now, if you’re having issues with your control panel, then it’s most likely because of the stuck buttons. This problem is extremely frustrating because it seems so simple but requires disassembly. The most often cause behind this is are the food particles that end up getting stuck in the button area. This isn’t your fault, but just the way it’s designed. These particles can clog up anything.

A lot of blenders will actually let you simply pop up the control panel and clean the buttons. If you have this option, just brush all the food debris off. If not, then you’ll have to disassemble the whole blender to clean it.

The trick to clean stuck food particles is to use a toothbrush to get to the really tiny areas. Some blenders will even let you disassemble only the bottom part. That way, you can reach the buttons and the blades. This will help you to fix all the problems without having to disassemble the whole thing.

Whenever you’re fixing any of your electronic appliances, it’s best to consult the owner’s manual.

Most of the problems that you are facing with these appliances are completely predictable, and the designers probably had them in mind when they were making the designs. That’s why so many of the blenders can be repaired more easily.

However, if any difficult problems occur, it’d be best to take your blender to the shop because tinkering around may only make it worse. The professionals will know what to do with it.
