What should I do if my Oral-B Pro 100 Precision Clean toothbrush won't turn on after changing the batteries?

If your Oral-B Pro 100 Precision Clean toothbrush is not working despite installing fresh batteries with the correct polarity, please try the following troubleshooting steps based on the manual:Check the Brush Head Attachment: Ensure the brush head is pushed down firmly until it clicks into place. If it is not seated correctly, the motor may not engage properly.Inspect Battery Contacts: Even if the toothbrush is clean, check the metal contacts inside the battery compartment and on the bottom cap for any signs of residue or moisture that might prevent a solid electrical connection.Verify Battery Type: Ensure you are using two standard AA (1.5V) batteries. Do not mix old and new batteries or different battery types.Test Without the Brush Head: Remove the brush head and try turning the handle on. If the metal shaft vibrates, the issue may be a jammed or defective brush head rather than the handle itself.If these steps do not resolve the issue, the device may have an internal fault. Since the product is relatively new, you should contact the manufacturer for support or warranty claims:Manufacturer: Procter & Gamble - HABA HubAddress: P&G Plaza, Cincinnati, OH 45202Website: www.oralb.com
