Dreame Weak Side Brush Motor Performance

Side brush spins intermittently or at very low speed without an error code.

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

Partial motor winding failure, High friction from debris, Loose motor connector, Failing motor driver circuit

Safety: Turn off the robot before removing the side brush.

Clean side brush and hub: Remove the side brush and clear all hair and debris from the hub and shaft.
Test motor alone: Run the robot with the side brush removed and observe the motor shaft speed.
Check wiring: Open the bottom cover and verify the side brush motor connector is secure.
Replace module: If the motor is weak or stalls easily, replace the side brush motor module. If the new motor behaves the same, the main control board motor driver may be faulty.
