Vacuum cuts out when using the motorized floor head; E3 appears on the display, and the handheld unit alone may work.

Safety first: Remove the battery pack and detach the motorized floor head from the wand or handheld unit before working on the brushroll.

• Clear brushroll: Turn the floor head upside down. Remove the brushroll cover (usually secured by a clip or a few screws). Cut away any hair, threads, and fibers with scissors, taking care not to cut the bristles.
• Check brushroll rotation: Spin the brushroll by hand. It should rotate freely. If it feels stiff or seized, inspect the end caps and bearings for debris or damage.
• Inspect for melted plastic: Look for heat damage around the brushroll ends or motor area. Melted plastic indicates prolonged stalling and likely motor damage.
• Check wiring and connector: Inspect the electrical connector pins between the wand and floor head for bent pins, corrosion, or looseness. Clean them gently with a dry cloth.
• Test without wand: Connect the floor head directly to the handheld unit (if the design allows) and test. If E3 still appears, the floor head assembly is likely faulty.
• Replace floor head: If the brushroll motor does not run or stalls immediately, even when clean and free, replace the complete Logik motorized floor head assembly or the brushroll motor module if sold separately.
