Cordless SEBO vacuum stops shortly after starting; red fault indicator flashes twice in a repeating pattern.

Safety first: Remove the battery pack before inspecting the motor or brush head. Do not run the motor with covers removed.

• Check for blockages: Remove the wand, floor nozzle, and dust bin. Inspect the air path from the nozzle inlet through the wand, hose, cyclone, and pre-motor filter area. Clear any clogs (hair, dust bunnies, debris) using a long brush or flexible rod.
• Inspect filters: Remove the pre-motor and exhaust filters. If they are heavily clogged, wash or replace according to SEBO instructions. Never run the vacuum without filters for extended periods.
• Spin test: With the housing open (battery removed), gently spin the motor fan (if accessible) with a plastic tool. It should rotate freely without grinding or tight spots. A stiff or noisy motor indicates bearing failure.
• Check for burning smell: If you noticed a strong electrical or burning smell before the E2 error, the motor windings may be damaged and the motor assembly should be replaced.
• Reset and test: Reassemble, reinstall clean filters, and refit the battery. Run the vacuum on low power first. If E2 returns quickly, the suction motor or motor driver on the PCB is likely defective and requires replacement.
