Electric toothbrush won't charge

Symptoms

• No light comes on when placed on the charger
• Charging light blinks but brush won't hold a charge
• Brush runs for only a few seconds before dying

Likely causes

• CommonMoisture or toothpaste residue on charging contactsBuildup on the base or brush contacts can block the charging connection.
• CommonBattery reaching end of lifeRechargeable batteries in toothbrushes typically last 1–3 years before losing capacity.
• PossibleCharging base not getting powerA dead outlet or faulty base can look like a brush problem.
• Less commonWater damage from prolonged exposureEven water-resistant brushes can fail internally after years of shower use.

What to do

1. Wipe both the brush's charging contacts and the base's contacts dry and clean.
2. Confirm the outlet works by plugging in another device.
3. Let the brush sit on the charger undisturbed for a full 12–24 hours.
4. Try a different outlet in case the original one is dead or on a switched circuit.
5. Check if the charging light behaves differently after cleaning contacts.
6. If the brush runs briefly then dies, the battery likely needs replacement, which most models don't support at home.
7. Contact the manufacturer if it's within warranty since many brands replace failed units.

Tools and parts

• Soft cloth

When to call a pro

If cleaning contacts and a full charge cycle don't help, most electric toothbrushes aren't user-repairable and are best replaced or handled under warranty.
