Cordless vacuum displays E14, and the LED on the motorised floorhead flashes; the brush stops intermittently.

Safety first: Remove the battery and disconnect the floorhead before working on it.

• Allow to cool: Allow the floorhead to cool for at least 20 to 30 minutes before further use.
• Clean brush bar thoroughly: Remove the brush bar and clear all hair and fibres from the bristles and end caps. Ensure the brush bar spins freely.
• Inspect air channels: Check the underside of the floorhead for blockages in the suction channel and around the brush motor housing.
• Use appropriate power setting: On very thick carpets, use a lower power setting or reduce pressure on the floorhead to avoid overloading the brush motor.
• Replace floorhead if needed: If E14 recurs quickly even after cleaning and cooling, the brush motor's thermal protection may be tripping due to an internal failure. Replace the motorised floorhead assembly.
