Why does my Bissell vacuum make a loud noise?

Vacuum cleaners are often noisy devices, but you can always tell when one is generating too much noise. Before you discard the machine, attempt to locate the cause of the noise. Shut off the machine to determine whether the noise was produced by something big in the hose. Also, consider using other brush attachments, as a brush attachment with damaged bearings will make a lot of noise. If these troubleshooting procedures don’t work, the engine may need to be serviced.

1st step

Remove the machine’s filter and bag to ensure they are not blocked or full of junk. Replace the bag or clean any filters according to your model’s recommendations. The engine will be noisy if there is a lot of junk in it.

2nd Step

Inspect the vacuum’s hose for any big particles that may be blocking the tube’s inside. A loud noise in the engine can be caused by large volumes of dust, as well as stones or other hard things that bounce.

3rd step

Remove the casing that hides your machine’s engine and check the fan for damage or blockage. Remove any dirt or debris that may be obstructing the fan’s movement. Check for any damage to the fan, such as bent or too sharp blades. Replace the fan blades as needed, and if the fan is broken, contact the vacuum maker. Instructions will be sent with the new item.

4th step

If the fan is loose on the assembly, tighten it with a ratchet. As the motor cranks, a loose fan makes a rattling sound.

5th step

Clean the engine’s frame of dirt and grime. Large amounts of dirt or dust in the vicinity of the motor might cause it to overheat, resulting in vibration and loud noise.

6th step

Examine the engine for corrosion. The engine must be changed if it is rusted.

7th step

If you notice a grinding noise coming from the vacuum, grease the engine bearings. Greasing is frequently done through engine ports or by removing the bearings. The actual greasing process, on the other hand, is model-specific. For this servicing, see your owner’s handbook or send the vacuum to a service expert.

8th step

Examine the vacuum cleaners inside for any other worn or damaged parts. Loud sounds can be made by worn or damaged parts. Remove the broken part and contact the vacuum maker for replacement materials, or bring the unit in for servicing.
