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.
Our Cordless Advanced Water Flosser, Cordless Select Water Flosser, ION Professional Water Flosser, and ION Water Flosser models feature a charge indicator light.
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.
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 when the indicator light indicates that the unit needs to be charged.
Fully charge the unit before extended periods of no use. We recommend fully charging every month when the unit is in storage.
Plug the power supply into the wall outlet and connect the magnetic plug to the unit for approximately 4.5-5 hours. When the batteries are in need of charging the charge indicator light will blink 3 times quickly. A complete recharge will take 4.5-5 hours.
Mouthwash or other recommended antibacterial solutions can be used in our Water Flossers. We recommend using no more than a 1:1 ratio of solution to water. After using additives, run at least one-half reservoir of plain water through the unit to flush the water pathway.
Do not use mouthwashes or additives that contain iodine, peroxide, baking soda, or water-insoluble concentrated oils (such as Tea Tree Oil). Use of these items can reduce the product performance and will shorten the life of the unit.
Do not use a salt/saline solution in any handheld cordless unit.
If additives are being used, it is highly recommended that the cleaning procedure is done at least once a month.
The hose and handle assembly kit is available for most models through our online store. To locate your product's model number, look for letters such as "WP", "WF", or "CC" on the bottom of the unit.
