Cordless vacuum shows F3; LED on the brush head may flash and the brush roll does not turn.

Safety first: Remove the battery and detach the brush head before cleaning contacts.

• Clean contacts: Inspect the metal pins and pads on both the wand and brush head. Wipe with a dry cloth. If there is light oxidation, gently rub with a pencil eraser, then wipe clean.
• Check for bent pins: Straighten slightly bent pins carefully with small pliers. Do not force them.
• Test without wand: If your model allows, connect the brush head directly to the handheld unit to bypass the wand. If it works, the wand wiring is likely faulty.
• Try another head: If you have another compatible Rowenta motorized head, test it. If F3 disappears, the original head is defective.
• Replace faulty component: Replace the wand or brush head assembly if continuity is lost or the PCB is faulty.
