Garbage Disposal Loose Blades

For the garbage disposal to work fluidly, it depends on the two blades. If you look at the disposer you will notice that they are attached to the impeller plate. The impeller plate, on the other hand, rotates with the help of the flying wheel.

Garbage Disposal Loose Blade

But once in a while, you will notice that the blades loosen up. This may arise due to different reasons including wear and tear. The garbage disposal blade, therefore, needs proper maintenance.

When you are sure the garbage disposal is loose, you can do the following to correct it.

Fixing the Loose Blades

  • Step 1- unplug

As with all other garbage disposal repair methods, you need to unplug it from the power source. Remember the power plug is below the sink and often on the wall next to the disposal unit.

Be sure that there’s no power transmitting before you start working on the disposer. If you can break the power from the main circuit breaker.

This assures you that there’s no power transmitting. You need to know that for sure because you will insert your hands into the disposer. Therefore, you should be sure you won’t grind your hands.

  • Step 2- check for any stuck objects

Notice that sometimes, you may be dealing with an obstruction. If there’s an obstruction in the form of a clog or a fork, the blades won’t grind.

You can easily find the obstruction by dipping your hands into the disposer and then moving the blades. If the impeller blades run smoothly side by side, then there’s no obstruction plus the blades are not loose.

However, if it’s moving up and down, it means the blades have gotten loose. Sometimes it could be that there’s an obstruction beneath it.

You can, however, use the flashlight torch to see inside clearly. This will show you where the clog is sometimes, though the food waste may have stuck under the blades. And this may cause the loosening of the blades.

You can use the nose pliers to remove the clog or even your hands now that your hands are in the disposer. You may find it hard to remove the waste sometimes. But using the nose pliers you can push the trash a few times to loosen it.

Next, let the water run through to clean the food waste altogether.

  • Step 3 fixing the blades

Begin by unscrewing the disposal screw that has it mounted on the sink. You can use the pipe wrench for this. Unscrew the nuts and then quickly the nuts will come out. You can go further to part the disposal so that you can see the blades correctly.

Loosen the center and side blades to release the top parts and the bottom parts. This, however, depends on your kind of garbage disposal. Some have these parts while others don’t.

Go to the loose blade’s connection then tighten the two bolts that hold it in place. Once you are sure that nothing is under the blades you can tighten the two bolts that hold the blades. This will tighten them and keep them in place.

  • Step 4 – clean it

To finish off the process, clean the sink flange and get rid of all kinds of grime and dirt. Use the piece of clothing to get rid of the trash.

Go on to reattach the disposer and screw it back to place. Then you can give it a powerful cleaning before you switch on the circuit bleaker. Plug and start it.

The way you restart it is by using the reset button. This will clear the clogs and repair it adequately.

How to Know If the Blades Are Loose

I like to tell people you will know when the blades have gotten loose.

First off, the sound it makes is different from the usual. It feels like the sound of the shrieking metals.

It can grind like the metal when you have loose blades, loose rivets, loose bearing or there’s a clog.

Another thing is that mostly the disposer doesn’t grind when you have loose blades. This is another good indication of loose blades.

How to Replace the Blades

  • Step one- safety

Confirm that you are safe by unplugging the disposal from under the sink. Once you have switched it off, you can give it a final confirmation when you turn it around to ensure it doesn’t turn.

In the process, have a bucket ready to secure the dripping water as you are working on the disposer. It’s harder when you have to wipe the water and the house at the same time.

  • Step 2- unscrew the deposer

You should have noticed by now that most of these operations require you to un attach the different parts that connect to the disposal unit. First off unscrew the dishwasher line and waste line. You want to remove it from under the sink before you can work on it.

Nevertheless, stay safe as you shouldn’t let the disposer hit your legs.

  • Step 3 replacing the blades

Next, you will need to replace the blades. So unbolt the blades in the disposal. Then once you loosen the bolts you can replace the blades. Buy the stainless steel blades and replace the old blades.

But this shouldn’t be the norm, and if you have to replace the blades now and then, you should consider buying a new set of blades.

Although you may opt to replace or repair the blades, I can’t say that it’s good to have the repair as much as you would rather have a new one. Most people assume that once it starts to loosen, it’s soon going to break down.

For the most part, they indicate that the disposer is wearing out altogether. This is unless you recently bought the disposer.


You ought to protect your blades and garbage disposal in all. Try to make sure you only use the disposer for the right reasons.

Don’t grind tough food like bones and fibrous food. These actions will limit its lifespan and therefore follow your guide on the dos and don’ts.
