  1. Water Reservoir

  1. Water Flosser Tip

Cleaning the reservoir is another main task to consider. In essence, you will have to pour antibacterial solution to it, direct the Waterpik water flosser tip to the sink and turn it on, to the maximum pressure.

Leaking Problems

The most common type of issues is related to water leaking. In general, it can come from the tip, handle, hose, base or a reservoir. Don’t forget that all Waterpik water flossers operate at high pressure, meaning that all of the components we have just mentioned must withstand it at all times. This type of fixing is more than just simple.

Fix: Depending on where the leaking comes, make sure to remove that component. Usually, you will need to perform Waterpik hose repair. Obviously, all you have to do is to replace an old hose with a brand new and you are done. Needed time is under 10 minutes if you are a beginner. In a case you see leaking from the reservoir, make sure the black valve is properly installed. If it isn’t, then you will have to purchase a replacement unit. Just in case, remove the old one, clean it and put it back to place. It should do the trick. Addition: You cannot repair Waterpik hose using duct tape, it simply won’t last!

If your reservoir or the entire unit dropped to the floor, the reservoir may have cracked. Repairs are possible with a glue gun, or adhesive, but it is a much better and smarter decision to purchase a replacement reservoir.

If the leaking comes from the tip, remove it and reinstall it. If it still leaks, install another one. If there is no leaning anymore, the problem is in the tip itself. Replace it.

Mineral Deposits Or Mold

If you have performed weekly cleaning, which we mentioned at the beginning, chances are low you will get this issue. In any other way, it is just a matter of time when you will have to deal with it. Mold and mineral debris will appear at the tip, hose, reservoir and even in order components. Sadly, this is perfectly normal and removing them is as easy as it gets.

Fix: Use white vinegar or hydrogen peroxide to fill the reservoir. Then, direct the tip to the sink and turn the device on. Make a short break and repeat the process. In essence, all the mold and mineral debris will be removed within a matter of minutes.

Hydrogen peroxide may be a more complicated alternative than vinegar, but it is stronger and therefore more efficient in removing the mentioned issues. After this, your water flosser will work better and without any, additional complications.

Lower Pressure Than Usual

Waterpik low pressure sounds like a severe malfunction, but it actually requires simple fix. If you hear the electric motor while the device is turned on and you still get a pressure on the tip, there are no severe damage to the unit. Keep in mind that all units have a variety of pressure settings, so this refers only to the highest pressure setting. The causes are related to the black valve in a reservoir, the reservoir itself and clogs.

Fix: First of all, inspect the device. Make sure all the components are installed properly and there are no damages. Make sure the black valve in a reservoir is properly cleaned and fitted as well. The last, but not least, check the tip and the opening on it. There should be sufficient amount of room for the water to pass.

In a case, a tip is clogged or something else is, make sure to clean it properly and to remove any obstacles. In addition, leaking may cause the low pressure as well, but you will have to perform inspection and fixes from the leakage section.

Waterpik Not Working

In this section, we will mention and explain all, the main malfunctions which can cause your Waterpik not to operate properly. The most common symptoms include not charging, switch on the handle doesn’t work or tip is worn out. Here we should add that in rare cases electric motor can stop working as well. If you do not hear the noise when you turn on the water flosser, chances are high the electric motor is damaged. You should contact the seller if the warranty still lasts. If the electric motor works, but the device stopped charging a while back, you have a damaged charging port or a battery.

Fix: The main issue here is in the charger. It can get damaged due to water exposure. The charging port may be damaged as well. Always check the cable for damages.

If a switch on a handle doesn’t work, you should disassemble the handle and try to diagnose the issue. Worn spring or broken switch are common issues here. If a tip doesn’t work properly it will have to be replaced. Always replace them after 3 or 6 months, depending on a version.
