Husqvarna Overly Sensitive Brush Overload Protection

Brushes stop when the unit encounters slight resistance, even on normal carpet

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

Weak brush motor, Excessive friction in brush bearings, Misadjusted overload sensor, Worn drive belt slipping

Safety: Unplug the Husqvarna carpet cleaner before servicing the brush system.

Service brush roll: Clean and lubricate brush end caps if serviceable. Replace the Husqvarna brush roll if bearings are worn.
Inspect belt: Replace a stretched or glazed belt that may be slipping under load.
Check motor: Test brush motor current draw; if high at no load, the motor may be failing and should be replaced.
Sensor calibration: If available in service mode, recalibrate the overload threshold per Husqvarna service instructions.
