Water Flosser comes with a 12 months warranty from the date of purchase. A dated sales receipt and eWarranty Registration Acknowledgement are required for warranty validation, Click HERE.

We do not cover warranty for water flossers that are not purchased from the local authorised distributor or resellers.

For first time use, prime the unit:

- If your unit has a black rubber valve in the water reservoir, ensure that the black valve is installed with the dome side facing up and the four-pronged side facing down to connect with the base of the unit.

- Fill reservoir at least half-full of water. Ensure the reservoir is firmly seated onto the base of the unit. Press down firmly to engage the reservoir to the base of the unit.

- Confirm the unit is plugged into an active electrical outlet.

- Set the Water Flosser to the highest pressure setting, and if the handle has an on/off slide switch, make sure it is in the ON position. Then point the handle downward towards the sink and turn the unit on; this generally starts the flow of water within 30 seconds.

- If this process fails to start the flow of water, insert a jet tip and gently draw on the tip as you would a drinking straw.

Drop in pressure or flow:

- It is recommended that when applicable, you replace tips every 3-6 months. (Consult the instruction manual for specific replacement information for each tip.)

- Add 2 tablespoons of white vinegar to a full reservoir of warm water.

 > If your tip is removable, remove the tip, set pressure control dial to high, place the handle in the sink.

 > With the unit in the OFF position, allow gravity to drain the vinegar solution through the Water Flosser.

 > Rinse by repeating with a full reservoir of clean warm water.

Water Flosser products are not intended to store liquid between uses - ensure your product is emptied after each use.

If your unit has a black rubber valve plugging the bottom of the reservoir tank:

- Remove the black rubber valve from the water tank by pushing it out from the bottom.

- Run the valve under warm water and massage with your fingers.

- Return the black valve to the tank. Ensure the dome side is facing up and the four-prong side is showing on the bottom.

The most common reason for little or no water flow is a clogged jet tip. You can troubleshoot this condition by removing the jet tip and observing if water bubbles up from the top when the device is powered on.

- To remove the tip, press the Tip Eject button (refer to your owner's manual if needed).

- To clean the tip, soak it in a container of hydrogen peroxide or white vinegar for 5-7 minutes. Rinse the tip under warm water.

Our Cordless Advanced (WP-563) Water Flosser models feature a charge indicator light.

For Cordless and Cordless Plus models:

To maximize the capacity and life of the rechargeable batteries, give the unit a full charge (24 hours) prior to the first use. Do not use the unit with the charger pin engaged. For extended battery life, the battery should be charged at least 8-10 hours after 7-10 reservoirs of water. Do not allow the product to completely discharge.

Fully charge the unit before extended periods of no use. The battery will bleed down its charge in 6-9 months. We recommend fully charging every month when the unit is in storage.

For Cordless Advanced model:

To maximize the capacity and life of the rechargeable batteries, give the unit a full charge (4 hours) prior to the first use. The unit should be charged 3-4 hours (until the battery charging light stops blinking) when the indicator light indicates that the unit needs to be charged.

Fully charge the unit before extended periods of no use. The battery will bleed down its charge in 6-9 months. We recommend fully charging every month when the unit is in storage.

If additives (such as mouthwash) are used, rinse the system with a reservoir full of clean water after each use. Failure to rinse the unit may result in loss of product performance and/or function. Growth of bacteria could also be enhanced.
