Why is my Sonicare Toothbrush Beeping While Charging?

Sonicare Toothbrush Beeping

Electric toothbrushes, like the Philips’ Sonicare brush, are time-proven to get into hard-to-reach places in your mouth. However, the beeping the brush makes while charging can get irritating pretty quickly, especially if you don’t know why it’s happening.

Although the beeping noise is generally attributed to the device charging, it can also mean there’s a problem. From an issue with the base to using an incorrect attachment, there can be several reasons for the beeping noise. You may even be entitled to a replacement from the company at no cost to you.

In this guide, we’ll cover our bases on all the common causes for beeping that aren’t from general charging. We’ll also give you some helpful information about maintaining your electric toothbrush.

Reasons why my Sonicare Toothbrush is beeping

1. There’s a problem with the base

If the toothbrush itself doesn’t look like anything is faulty, and it seems to work just fine off the base, you may be experiencing issues with the base itself. The device’s charging cord may be having trouble sending an adequate amount of power from the adapter to the charging base.

When this is the issue, you can call Philips’ customer support team, purchase a replacement charger, or try plugging the charger and base into a different outlet. Before resorting to purchasing a replacement, it’s always helpful to check your outlets at home and reach out to the company first. In many cases, your product may have a warranty that constitutes a free replacement mailed to you.

2. It needs a reset

Like any other electronic device, the beeping noise could be due to some type of electrical glitch. To fix that glitch or any other technical issue, you can simply reset the toothbrush. To hard reset your toothbrush, all you need to do is set it on the charger and hold down both the intensity and power buttons for five seconds.

You should hear three beeps and the green light should turn on. Walk away and wait a few seconds before checking on the brush. If resetting helped, you shouldn’t hear beeping anymore.

3. You need to replace your toothbrush head

If the beeping is happening and it’s been at least three months since the last time you changed the brush head, it’s probably time to change the head out. Depending on how often you brush and how you store the brush, you may need to replace the head sooner than the recommended three months.

It’s also possible that your Sonicare toothbrush is one of the models that comes with a reminder function. This reminder will go off whenever it’s time to replace the brush head with a new one. Although you can turn this function off, it’s helpful to keep it on to keep you accountable.

When it comes time to replace the head, you need to pull the old one away from the handle and slide on the new head in its place. When attaching the new head, make sure the metal prongs correctly line up so the head fits entirely onto the handle.

4. Attachment installation is incorrect

When the attachment head is installed incorrectly onto the handle, it means the connection between the two is compromised and you may not get full power. If the beeping keeps happening, try removing the brush head and reinstalling it again while carefully ensuring all parts line up evenly.

5. You are using the wrong attachment

Although Sonicare toothbrush heads are interchangeable, older brush head models may not work well with the sensors of a newer Sonicare brush. The beeping may also occur if you try using an attachment from another brand on your Sonicare toothbrush. Oral-B, for example, is explicitly advised against because it can mess with the integrity and performance of your toothbrush.

Brush maintenance best practices

1. How often should I replace my brush?

Philips recommends replacing the toothbrush head of your Sonicare toothbrush at least once every three months. However, if you use the brush more often, or you don’t always store it properly, you may need to replace the brush sooner than that.

A solid indicator that it’s time to replace your brush head is if you notice the blue indicator bristles are wearing out. These recommendations come with the assumption that a person is brushing their teeth regularly, at least twice per day.

2. Warranties and Sonicare toothbrush lifespan

Of course, it’s always possible that the product just happened to arrive at the store faulty and you were the unlucky one to purchase it. When this is the case, there’s a warranty promise in place that generally allows you up to two years to make a warranty claim about a faulty product.

If the warranty is approved, Philips Sonicare will send you a replacement toothbrush at no additional cost to you. Keep in mind that to file a warranty claim with Philips, you’ll need to have proof of purchase in the form of a receipt or the original packaging.

The following indicators are usually pretty clear if the product is faulty.

Look out for these signs paired with a consistent beeping while charging:

  • The inability to hold a charge
  • Turning off after a few uses
  • Uncharacteristically loud beeping
  • Not reaching full range of motion

While you can file a faulty product claim for up to two years from the date of purchase, it’s best to send in your claim as soon as possible to ensure the company will accept it. The longer you wait, the less likely it will make it through acceptance in time.

Parting thoughts

The reason behind your Sonicare toothbrush’s excessive beeping can be tricky to pinpoint. However, once you figure out the source of the problem, it’s generally pretty easy to solve the issue. Whether it’s just charging or it’s an entirely faulty product, knowing what is up with your toothbrush will help put your mind at ease.

We hope this article has helped you better understand why your Philips Sonicare toothbrush is beeping while charging.
