F5 appears, vacuum runs but main brush does not spin even though suction is present.

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

Open-circuit brush motor, Broken wiring in floor head, Faulty brush motor driver transistor on PCB, Overheated brush motor winding

Safety: Turn off and remove the battery.

Check for jams: Remove the floor head and brushroll. Ensure the brushroll spins freely by hand.
Inspect wiring: Look for visible damage to the cable between the wand and floor head, and at the swivel joint.
Test with another head (if available): Attach a different motorized head or mini power brush. If that spins, the original floor head is faulty.

If F5 persists with a known-good head, the main body’s brush motor driver circuit may be defective and requires PCB-level repair.
