6 reasons why your blender is stuck to the base

These are some common reasons why your blender is stuck to the base.

1. Leakage in the bearing seals

The bearing seal is located on the bearing of a blade assembly.

It prevents the blender jar from leaking.

But if you have been using this blender for a long time, then chances are that the seal of the bearing can damage or leak.

It can cause the blender to stick to the base.

2. Corroded bearing

A bearing is a ball-shaped metal ring that locates under the blade.

The bearing helps to rotate the blade of the blender.

If the bearing is damaged or worn out from long uses, then it can cause the blender to stick to the base.

If the blender’s seal leaks, the bearing can become wet and corroded.

In all cases, it can cause the blender to stick to the base.

3. Corroded blade shaft

The shaft is a small metal rod adjusted with the blade head.

It helps to rotate the blade.

But if the blender’s seal is leaked, it can corrode the shaft.

You can find rust on the blade shaft.

It can prevent the blade from rotating and also be the reason why the blender is stuck to the base.

4. Broken plastic gear

You can find two plastic gears in a blender.

One is located at the bottom of the blender jar, and another is on the base of a blender.

The base gear spins along with the base motor of the blender.

When you put the jar on the base, the base gear attaches to the jar gear and helps the blade to move when the motor is spinning.

If one of the gears is broken, the blender gets stuck to the base and won’t work properly.

5. Corroded plastic gear

If the plastic gear is corroded and you find rust, the gear gets jammed.

You can find rust if you wet your blender jar and dry it with a dry cloth.

That can be the reason why it is stuck to the base.

6. Jammed blade

There are two reasons why your blender blade is jammed.

The first reason is that debris and food particles clog the space between the blade and the base.

Another reason the blade has rust.
