The blender smells like something is burning.

If the blender has not been used for more than a few days, the blade assembly can get stalled and may cause a burning smell when used. To prevent this, carefully use your hands or channel lock pliers if necessary and manually rotate the blades before use.

The drive coupling is the piece attached to the base of your blender that causes the blades to turn. After many uses this part may wear down and begin to slip, this could be causing the burning smell.  Find out how to easily replace the coupling by following the 51BL29 drive coupling replacement guide.

The blender will not operate when turned on.

If the blender shut down during use, it is most likely is due to overheating of the circuits. To fix this, turn off the blender and let it cool down for five minutes before using again.

The blender is leaking out of the bottom of the blade assembly.

If the bottom of the blender is leaking, it may be caused by a loosened nut that holds the blade assembly together. To tighten the nut, follow these steps:

  1. Remove the blades by reaching inside the blender and loosening the nut on top of the blades, using pliers if necessary.

  2. Carefully remove the blades from the blender.

  3. Turn over the blender, exposing the bottom.

  4. Grab the wheel on the bottom of the blender and pull out the axle, exposing a flat nut.

  5. Tighten this nut counterclockwise to seal the bottom of the blade assembly.

  6. Replace the axle into the bottom of the blender.

  7. Turn the blender over and replace the blades and the nut securing them.

  8. Fill the blender with water and test for leaking.

The blades are not dicing properly.

If the blades are not dicing properly, it may be due to dulled blades. To sharpen the blades, follow these steps:

  1. Carefully remove the blades from the blender to rinse and dry them.

  2. Run the edge of one of the blades on a sharpening stone, being careful to maintain the same sharp edge angle of the blade.

  3. Once you have finished one side of the blade, flip it over and repeat with the other side of the blade.

  4. Repeat steps 3 and 4 for all of the blades.

  5. Rinse and dry the blades and replace into blender along with the nut securing them.

Carefully remove the blades by reaching inside the blender and loosening the nut on top of the blades, using pliers if necessary.
