Sonicare Toothbrush Spare Parts & Chargers

There are a wide range of Philips Sonicare toothbrushes and many of them require the occasional spare part to keep them running, particularly mechanical parts such as the seals, drive components and the motor/solenoid.

Below we show you some of the parts used in various Sonicare toothbrushes, and chargers, and show you where to buy replacements.

Which Sonicare Brush Do I Have?

Firstly, you need to determine which model of Sonicare toothbrush you have! The most accurate way is to find the HX number marked on the bottom of your toothbrush handle. In the example below this is marked HX9340. You can ignore the last two digits as these generally only refer to the colour of the handle. So this brush is part of the DiamondClean HX9300 series. Parts are generally interchangeable between any of HX9300 models (HX9330, HX9350, etc.)


Part Interchangeability

Parts for Philips Sonicare toothbrushes are generally interchangeable between brushes that share the first 2 digits after the HX in their part number. So for example, with the original HealthyWhite HX6700 series your brush might be marked HX6710 but it will use the same parts as the HX6720, HX6730, and so on. The HX6900 series has some large variations within the series so for the PCB or motor do ensure the parts match your brush.

Available Spare Parts

Below we list some of the commonly requested spare parts for Philips Sonicare toothbrushes.

Shaft Seals

The shaft seal fits between the metal shaft that drives the motion of the toothbrush head and the plastic casing of your Sonicare. These small seals are all that stands between the delicate electronics inside your Sonicare toothbrush and the water that gathers around the bottom of the toothbrush head. They can go mouldy and perish, allowing water to seep inside the toothbrush handle where it can start to corrode the motor, PCB and electronic components. Below you can see a new flexible seal on the right, with a new solid plastic seal retainer/cover on the left.


These seals are pretty universal across all Sonicare brushes. The replacement seals are available on eBay from the following suppliers:

Shaft Connector Block

This die-cast metal block connects the stainless steel output shaft that moves the toothbrush head to the motor/solenoid of your Sonicare. It can fracture and break causing the motor to disconnect from the output shaft. Remember that when a replacement part is stated as being (for example) for the HX9340 it should fit all HX9300 models such as the HX9330, HX9360, etc. Some replacement shafts might come with new seals included.


Replacement shafts are available on eBay from the following suppliers:

Motor / Solenoid

This is the heart of your Sonicare toothbrush as it produces the mechanical movement from the electrical energy stored in the battery. Most Li-ion powered Sonicare brushes use the same motor to run at 31k (31,000 oscillations per minute), although some models run at a higher speed of 62k (the ProtectiveClean HX6800 series, certain HX6900 FlexCare models, the FlexCare Platinum HX9100 series, the “5 Series” or HealthyWhite+ HX8900 series and the DiamondClean Smart HX9900 series) so these will possibly require a slightly different motor.


Replacement motors generally come with a new shaft attached and sometimes new seals as well. They are available on eBay from the following suppliers:

PCB (Printed Circuit Board)

The PCB or mainboard of your Sonicare is susceptible to moisture damage. Water entering the handle can cause corrosion on the fine metallic tracks of the PCB which can break the tracks. Make sure when buying a replacement that it is from the same HX series as your existing brush as different series have the buttons and LEDs in different positions. Some of the HX6900 series brushes have the LEDs in slightly different positions such as the HX6950 which varies from the HX6920 and HX6930 positions. The brushing modes might be in a different order too.


Replacement PCBs generally come with the charging coil and plastic frame attached, and sometimes even a new battery too! They are available on eBay from the following suppliers:

Power / Mode Button

The rubber and plastic buttons on your Sonicare toothbrush can gradually wear out, meaning that they either don’t allow the switch underneath to be activated properly or they allow moisture inside the handle.


Replacement power button covers and mode selection buttons to cover the switches on your Sonicare toothbrush are available on eBay here:

Rechargeable Battery

With a limited service life at some point you will need to replace the battery inside your Sonicare toothbrush.

There are a few types of charger originally supplied with Sonicare toothbrushes. Each charger has an HX number marked on it to help identify it. When buying a replacement Sonicare charger check that it is rated for the correct electricity voltage in your home and that it has a suitable electrical plug attached.

The most common type of charger is the HX6100 shown below. It is compatible with nearly all Sonicare toothbrushes apart from DiamondClean models. It sometimes supplied with an optional shroud or surround which includes holders for your brush heads. Replacements are commonly available – see below for links.

Also compatible with the same models as the HX6100 above, are the HX6150 and HX6160 chargers which include a built-in UV sanitizer to sanitize your toothbrush heads. The compartment on the charger opens up for you to place your toothbrush heads in for sterilization/disinfection. Spare UV bulbs/lamps are also available.

The Sonicare DiamondClean toothbrushes have their own special charging base, which can also hold a glass or clear surround for your DiamondClean to sit in. This is known as the HX9100 model of charger.

The DiamondClean Sonicares were also available with a charging travel case (HX9210) which allows you to store your toothbrush with its heads and easily recharge it whilst travelling. The travel case is available in various colours, including grey, black, purple and pink.

  1. My hx6930 brush could not be turned on after turned on itself for several times, even battery was full. Need an on/off switch.

    1. It could be water getting inside the toothbrush handle. Open up the casing (use our guides to help) and let the internals dry out for 24 hours. Then replace the seal at the top.

  2. I need the rubber on off switch cover for a HX6930. Does anyone sell those small parts?

    1. We’ve now added power switch covers and mode buttons to the article above.

  3. my Sonicare DiamondClean does not charge. Instead it vibrates and flashes lights in the following pattern: 2 short green, 1 long amber. Any thoughts what this might mean?

    1. It might have moisture inside the handle casing. Open the handle using our DiamondClean repair guide and allow the innards to dry out for 24 hours.

  4. I cannot find the replacement toothbrush handle to fit model FC/A110-120 V a.c 50-60 Hz 1.5W

    1. Hi Barbara, are those markings off a Sonicare charger? And have you lost the whole toothbrush?

  5. I need a charger for my Philips sonicare
    Is this possible?
    I left mine overseas😔

  6. Help! My dog actually ate the little cone piece that is between the main body and the toothbrush. My toothbrush is an HX685T. Is there a replacement part I can but or will I have to walk around with a nasty smile until I can afford another Philips Sonicare?

    1. The rubber seal or plastic stopper? Yes these are available as spares – see the article above.

  7. I need the start button for a Sonicare HX6530.
    Is this part available?
    Thank You

    1. Only if someone is selling one. Have a look at the eBay link for buttons/switches. Any sellers will be listed.

  8. Just bought travel sonic care at CVS pharmacy and was wondering where to buy replacement heads (comes with one extra in package).

    1. What is the full name and model number of your toothbrush?

  9. Dear reader, Philips send me two times a wrong Sonicare type HX938B (black model) but no charging case. My son has a model HX939B(also black) and a charging case HX9210. Don’t want to dispose them as they are brand new so want to charge them but don’t charge in the glass and either in the travel case of what came with the HX939 model. Would expect it would work as they are in the same HX93.. serie but it doesn’t so I assume I need another charger but any idea which model or charging power ( Volts, Watt) is needed and where can I purchase one?
    Thanks in advance for your feedback and help.

    1. I would expect the HX938B DiamondClean brushes to charge in the standard DiamondClean glass charger and in the charging case. If they are deeply discharged they might need a few hours on charge before showing any lights. Did they come with their own charger?

      1. no, as the original one the HX939B made a lot of noise so they only send the brush without the chargers. Will put it in the charger glass or travel case and see what happen. Will let you know.

  10. I have the Philips sonicare HX3220B. It has a slightly bent shaft. Which replacement heads are compatible?

    1. The HX3220 CleanCare+ and other Sonicare brushes with a wavy shaft have a ‘click-on brush head system’ which is featured on these Philips Sonicare toothbrushes: PowerUp Battery, Essence+, Elite+ and CleanCare+
      The Cleancare+ HX3200 series brushes (HX3210, HX3220, HX3230) were supplied with a brush head marked C1, and replacement Sonicare C1 toothbrush heads are available new on eBay here.

  11. The stainless steel shaft came out of the aluminium block on my HX 6390. Reinstalled it but it comes out too easily now. Do I need to drive the shaft in harder, or is there a replacement assembly, or another solution?

    1. It’s probably best to get a new shaft assembly unless you want to experiment with 2-part epoxy glue. This might affect the head alignment, however.

  12. Hello,
    I’m looking for the seal kit for an HX6920.
    I seen a link to the top seals but can’t find the bottom black o-ring seal.

    Thanks in advance

    1. You’ll be able to use a generic thin o-ring for the seal around the bottom cap. Your local hardware store might have a suitable one, or buy a selection pack.
