Steps

Goal: Confirm the symptom, rule out power and head attachment, then isolate the drive fault.

  • Press the power button. Confirm the brush turns on but the head does not spin or vibrate.
  • Good: The brush responds but the head stays still—drive fault. Proceed to Check charge and head.
  • Bad: The brush does not power on—see charging guide.

Check charge and head

Goal: Rule out low battery and loose head before cleaning or replacing.

  • Place the brush on the charging base and leave it for several hours. Try again.
  • Remove the head and reattach it firmly until it clicks or locks. Check the owner’s manual for the correct attachment method.
  • Good: The brush is charged and the head is secure. Proceed to Clean head connection.
  • Bad: The brush is dead or the head will not stay on—fix charging or head first.

Clean head connection

Goal: Remove debris that blocks movement.

  • Remove the brush head. Wipe the stem and the inside of the head with a dry cloth. Use a toothpick or soft brush to clear any stuck material. Reattach the head.
  • Good: Connection is clean. Test again. If it spins, debris was the cause.
  • Bad: The stem is damaged or worn—replacement may be needed.

Replace head or brush

Goal: Try a new head first; replace the brush if the motor has failed.

  • If you have a spare head, try it. A new head that spins means the old head was faulty—replace it. If no head spins, the motor or drive has failed—replace the brush.
  • Most electric toothbrushes have sealed motors; repair is not practical. Replace the brush with a compatible model.
  • Good: The head spins or vibrates after replacement.
  • Bad: No spare head—replace the head first (often fixes it), then the brush if it still does not spin.

When to get help

Electric toothbrushes are typically inexpensive. If cleaning and replacing the head do not fix it, replacing the brush is often more practical than repair. Call a technician only for a high-end unit where professional diagnosis may be worth the cost.

Verification

  • The brush powers on and the head spins or vibrates when the button is pressed.
  • The head stays securely attached during use.
  • No unusual noise or overheating from the handle.

Escalation ladder

Work from the device outward. Stop when the problem is fixed.

  1. Confirm symptom Verify the brush powers on but the head does not spin; rule out power-on failure.
  2. Charge and head Check that the brush is charged and the head is locked on correctly.
  3. Clean connection Remove debris from the head connection; clean the stem and head.
  4. Replace head or brush Try a new head; if it spins, replace the old head. If no head spins, replace the brush.
  5. Replace unit If the motor has failed, replace the brush—most units are sealed and not repairable.

What to capture if you need help

Before calling support or posting for help, have these ready. It speeds everything up.

  • Whether the brush powers on (indicator or sound)
  • Whether a different head spins
  • Steps already tried

Does the brush power on but the head not spin?

Press the power button. If the brush turns on but the head stays still, the drive or head has failed. If the brush does not power on, that is a charging problem.

Press the power button. Good: brush responds but head does not spin—drive fault. Bad: brush does not power on—see charging guide.

You can change your answer later.

Is the brush charged and the head locked on?

Low battery and loose head can cause no movement.

Charge the brush for several hours. Remove and reattach the head firmly until it clicks or locks. Good: charged and head secure. Bad: head will not stay on or brush is dead—fix charging or head first.

You can change your answer later.

Is the head connection clean?

Debris in the connection can block movement.

Remove the brush head. Wipe the stem and inside of the head. Clear any debris. Reattach. Good: connection clean. Bad: stem damaged or worn—may need replacement.

You can change your answer later.

Clean connection and retest

Clean the stem and head, reattach, and test. If it spins, debris was the cause. If not, try a new head.

Does a different head spin?

A worn head can fail while the motor works.

Try a spare head or new head. If it spins, the old head was faulty—replace it. If no head spins, the motor or drive has failed—replace the brush. Good: you identified the fault. Bad: no spare—replace head first (often fixes it), then brush if needed.

You can change your answer later.

Replace the head

Replace the brush head with a compatible model. The brush should spin. Replace heads every 3–6 months per manufacturer guidance.

Replace the brush

The motor or drive has failed. Most electric toothbrushes have sealed motors—replace the brush. You should see the brush spinning after replacement.

Replace or call a pro

If charge or head attachment cannot be fixed, or if cleaning and a new head do not resolve it, replace the brush. Electric toothbrushes are often low-cost—replacement is usually more practical than repair. Call a technician only for high-end units.
