Hitachi Mechanical Noise / Bearing Wear

Vacuum is excessively loud compared to normal operation.

This repair may involve working with high voltage components or water connections. Always unplug the appliance before removing any panels.

If you are not confident in your ability to perform this repair safely, we strongly recommend contacting a professional technician.

Possible Causes

Worn motor bearings, Debris contacting the fan impeller, Cracked fan blade, Loose internal mounting screws

Safety first: Remove the battery before inspection.

Check for external causes: Remove the nozzle and pipe, then run only the main body. If the noise decreases, the issue is in the nozzle or pipe.
Inspect nozzle: Check the brush roll and wheels for debris or damage that could cause rattling or scraping.
Listen to motor: If the loud noise persists with only the main body, the motor bearings or fan may be damaged.

Internal motor or fan damage requires replacement of the motor assembly and should be handled by a service center.
