Cordless vacuum stops shortly after starting and E1 appears on the LED display or battery indicator blinks in a repeating single-flash pattern.

Safety first: Turn the vacuum OFF and remove the battery pack from the Sencor cordless vacuum before any inspection. Never work on the brushroll while the unit is powered.

• Check for jams: Lay the floor nozzle upside down. Remove the brushroll cover (usually a latch or a few screws). Pull out the main brushroll and cut away hair, threads, and pet fur from the bristles and end caps.
• Inspect end bearings: Spin the brushroll by hand. If it feels tight, gritty, or does not spin freely, clean the end caps and bearing seats. If melted or cracked, replace the brushroll assembly.
• Clear air channels: Check the suction channel in the floor nozzle and the connection tube for blockages (toys, paper, gravel). Remove any obstruction.
• Cool down the motor: Leave the vacuum off with the battery removed for at least 30 minutes to allow the brush motor to cool. Overheated motors can trigger E1.
• Reassemble and test: Reinstall the brushroll and cover, refit the battery, and test on a hard floor first. If E1 returns immediately with a free-spinning brush, the brush motor may be failing and should be replaced.
