Cordless vacuum makes a loud high-pitched whine or grinding noise during operation, louder than when new.

Safety first: Remove the battery and wait for the motor to stop completely before opening.

• 1. Rule out external causes: Remove the floor head and wand, then run the main body alone. If the noise persists, it is likely from the motor.
• 2. Inspect for debris: Remove the dust bin and filters to access the motor inlet. Use a torch to look for foreign objects near the fan and remove carefully.
• 3. Check for play: With the unit open (if possible), gently move the motor shaft or impeller. Excessive side-to-side movement indicates worn bearings.
• 4. Avoid further damage: Do not continue using the vacuum if the motor is grinding; this can lead to complete failure and potential overheating.
• 5. Replace motor assembly: Order the correct Beko motor assembly for your model and replace the entire unit, as bearings are not usually serviceable.
