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 series models (HX9330, HX9350, etc.)
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. Watch out if you have a HX6900 series toothbrush as there are some large variations within the series so for the PCB or motor do ensure the parts match your actual brush.
Available Spare Parts
Below we list some of the commonly requested spare parts for Philips Sonicare toothbrushes.
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. New replacement seals are available on eBay from the following suppliers:
- Philips Sonicare Seals – eBay UK
- Philips Sonicare Seals – eBay.com
- Philips Sonicare Seals – eBay Australia
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.
New replacement shafts are available on eBay from the following suppliers:

Motor / Electromagnet / Solenoid
The electromagnet is the heart of your Sonicare toothbrush as when coupled to the permanent magnet on the drivetrain it produces mechanical movement from the electrical energy stored in the battery. Most Li-ion powered Sonicare brushes use the same motor/electromagnet 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 electromagnets generally come with a new shaft attached and sometimes new seals as well. They are available brand new on eBay from the following suppliers:
- Philips Sonicare electromagnets/motors on eBay UK
- Philips Sonicare electromagnets/motors on eBay.com
- Philips Sonicare electromagnets/motors on eBay Australia
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 new on eBay from the following suppliers:
- HX9300 series PCB by Light Blue Digital on eBay
- HX6900 series PCB by Light Blue Digital on eBay (check LED position)
- HX6700 series PCB by Light Blue Digital on eBay

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 new on eBay here:

- Philips Sonicare buttons and switches on eBay.com

The surface-mount momentary switch on the PCB of your brush under the rubber/plastic button can sometimes wear out. These SPST, normally-open switches can be replaced with similar 5mm square, 1.5mm high tactile switches. However, it is more likely that corrosion has damaged the PCB tracks leading to the switch so inspect these carefully. You can test your existing switch by momentarily shorting across two of its diagonally opposite pins. If this powers up your toothbrush then the switch is at fault.

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