Waterpik Flosser Spare Parts

There are a wide range of Waterpik cordless dental water flossers available and many of them require an occasional spare part to keep them running, especially parts such as replacement tips, the battery and the motor.

Waterpik WP-450 battery replacement guide

Below we list some of the parts used in various Waterpik water flossers and show you where to buy replacements.

For instructions on how to open your Waterpik to fit replacement parts see our online repair guides here.

Which Waterpik Flosser Do I Have?

First you need to determine which model of Waterpik you have. The easiest way is to find the WP- model number marked on the flosser. In the example below the flosser is marked model WP-450 behind the reservoir. Below that is the serial number and a localised part number (WP450UK in this case.) You can generally ignore any letters after the numbers as these refer to your geographic region.

Part Interchangeability

Parts for Waterpik flossers are generally interchangeable between flossers that share the first 2 digits after the WP- in their part number. The third digit usually only indicates the colour. So, for example, within the WP-460 series your flosser might be a WP-462 but it will use the same parts as the WP-463, WP-464 and so on. Bear this in mind when looking for spare parts for your flosser.

The WP-440, WP-450 and WP-460 series are generally identical apart from colour. Listed below are some of the Waterpik Cordless Flosser series available:

Available Spare Parts

Below we list some of the commonly required spare parts for Waterpik water flossers, including spare tips, water tanks, replacement motors, replacement flosser batteries and new chargers.

Tips/Nozzles/Jets

The water jet tips for your Waterpik are pretty universal across all Waterpik water flossers. The replacement tips are available on eBay from the following suppliers:

Water Reservoir Tank

The plastic reservoir tank on your Waterpik flosser can often start to go cloudy and can also suffer from a build-up of limescale or mould from the water. The plastic can also crack meaning that the water reservoir leaks. Lids can also break. You can replace your reservoir with one of a different colour as long as it is from the same model series to make sure that it fits.

Replacement Waterpik reservoir tanks and lids are available to buy on eBay from the following suppliers:

Reservoir Tank Plug

The filler door/stopper cap that covers the water filling hole in the reservoir tank can easily break or snap off and get lost. This cover plug seals the reservoir to stop water leaking out during use.

Replacement reservoir tank plugs are available to buy on eBay from the following suppliers:

Motor

The motor is the heart of your Waterpik as it drives the pump using the electrical energy stored in the battery. This Waterpik WP-450 was fitted with a Mabuchi FC-280SA-3540 motor:

Make sure that your replacement motor comes with the correct gear attached. Otherwise you will need to use a miniature gear puller to remove the gear from your old motor and press it onto the shaft of your new motor. Replacement motors are available to buy on eBay from the following suppliers:

Rechargeable Battery

Rechargeable batteries have a limited service-life so at some point you will need to replace the rechargeable battery inside your flosser. We have a comprehensive battery replacement guide for the Waterpik WP-400 series (including WP-450 and WP-460 models) available online here.

Charger

There are a few thing to consider when buying a replacement charger for your cordless Waterpik flosser.

The easiest way to get the correct replacement charger is to buy one with matching part number marked on the charger. This is generally a model number starting YL or U marked on your existing AC adaptor.

North American spec charger for Waterpik flossers

If you do not have your original Waterpik charger because it has been lost and you need to find a new one then make sure you buy a new charger with the following specifications:

  1. It must have the correct physical mains plug for connecting to your domestic electrical supply, and the correct input voltage.
  2. It must have the correct output plug or induction connector for connecting to your Waterpik flosser (there are several types)
  3. It must have the correct output voltage, current and current type (AC or DC)

The most common charger type in North America is the YLA-03010. This is an AC/AC adaptor. It has a 2-pin mains input plug to suit US/Canadian wall sockets. The rated input is 120V AC at 60Hz with an output of 3V AC (∿) at 100mA current. The output plug on this charger is known as the D type and has two separate prongs to fit the “o D” shaped connector in the flosser. This charger will fit most WP-400 series Waterpik flossers apart from some older versions of the WP-450 which had a triangular connector socket known as the M type on the front.

D Type connector used on most Waterpik cordless flossers:

M Type connector used on some older versions of the WP-450 flosser:

m-shape-waterpik-charger-plug

Other charger part numbers for North America include YL-35-030100A and U030010A12, the latter of which comes with a triangular M type plug to fit the flosser. These both have an output of 3V AC at 100mA.

In Europe the chargers are AC/DC rather than AC/AC adaptors and are rated at 220V to 240V AC input voltage at 50Hz and have a 3V DC (⎓) output at 100mA current. For example, the part number for the UK model Waterpik charger is YL-35-030100D. Below is a photo of the continental European Waterpik charger with 2-pin AC input plug.

  1. Hello. I can’t find the D Type connector I bought my waterpik flousser in Florida but I need an European charger to connect my product in France. Can you send me a link? I can’t find something in eBays.
    Thank you.

    1. Try contacting waterpik.nl for a European 2-pin charger.

  2. Cuanto tiempo tarda en cargar la bateria

    1. The original battery takes 24 hours for a full charge. Our upgrade 1800mAh battery takes 30 hours. You can interrupt the charge to use the Waterpik.

  3. Hi. I need a charger that is compatible with New Zealand power supply.

    Thanks

    1. Hi Jenny, are there NZ contact details on the box or instructions? If not, try sales@pharmabroker.co.nz

  4. Where do you find the serial number on a 460m

    1. The serial number for the WP-460M is marked on the back behind the water reservoir. Unclip the reservoir at the bottom and slide the reservoir down to reveal the serial number and model number.

  5. Do you sell replacement M type sockets? The pins on mine have corroded.

    1. Sorry, we don’t sell the Waterpik charging sockets. You might be able to clean up the pins using cotton buds (Q-tips) and alcohol.

  6. Hello Good Morning!

    I`m from Brazil.
    I bought one WP 450 and the motor is damaged . I need the one spare parts.
    The model motor is FC-280SA-3540.
    Could you tell me, how I can buy the new motor ?\

    Than you
    Best Regards
    Leandro

    1. Hi Leandro, You need to find a seller who will send to Brazil, or a friend or relative in a country that they will send it to. Alternatively, a hobby shop (model cars, model planes) that is local to you might have a suitable replacement motor, for example a 3V 280 motor with flat sides.

  7. Hi

    2. Hey Tsachi,
      Did you manage to find a charger in IL?
      have a link to share maybe?

      Thanks!

  8. Hi,
    I’ve got the waterpik model WP-450 purchased in the US. I need to use it in Israel (220v 50hz)
    I see that the EU version of the charger is ac\dc adapter rather than the ac\ac adapter that came with my device. are they interchangeable? can I use a 3v dc input to the device?

    Thanks!
