Cordless vacuum shows E06 and will not start or immediately stops, often after the battery has been recently replaced or removed.

Safety first: Remove the battery and unplug the charger before inspecting contacts.

• 1. Confirm battery type: Ensure you are using a genuine Beko battery pack designed for your exact cordless model. Third-party packs may not communicate correctly and trigger E06.
• 2. Clean contacts: Inspect the metal contacts on both the battery and the vacuum body. Use a dry cloth or cotton swab to remove dust or light oxidation. Do not use water or abrasive materials.
• 3. Check for bent pins: Look closely for any bent or recessed pins in the battery bay. If a pin is bent, carefully straighten it with a small non-metallic tool. Avoid shorting pins together.
• 4. Reseat and reset: Reinsert the battery firmly until it clicks. Press and hold the power button for 10–15 seconds to reset the control electronics, then try again.
• 5. Test with another battery: If possible, test with a known-good Beko battery. If the error disappears, your original battery pack is faulty and should be replaced.
• 6. Main PCB fault: If multiple good batteries all show E06, the main control PCB may have a communication fault and will likely need replacement by a technician.
