From the whole house to the under-sink to the countertop, Aquasana provides water filtration systems of various kinds and sizes. With that versatility, comes a myriad of issues. So, if your Aquasana water filtration system is not working, and you are wondering why, you’ve come to the right place. 

It can happen due to a power issue, or a faulty filter. In this article, we’ll explain all the possible reasons and how you can go about fixing them. 

What Causes Aquasana to Malfunction and How to Fix It

Below we’ve mentioned every possible cause for which your Aquasana water filter might not work and most importantly how you can fix it.

Power Surge

If your Aquasana water filter is not working and you see a purple indicator LED blinking, it’s happened because of a power surge. It won’t start functioning normally again as long as the LED is blinking purple.

To fix it, you need to unplug the unit, then plug it in. Then use a pin to hold down the reset button until the purple indicator goes away.

The pump Isn’t Primed

If the pump isn’t primed properly, you will hear the pump running, but no water will dispense. Improper priming can happen at any stage of the filter’s life.

To fix it, remove the dock. Inside you’ll find a cartridge, remove it as well. Now run the system without the filter. Now place the filter in the dock, and let the system run for 10 more minutes. This will complete the flushing process. Everything should work fine now.

Clogged Cartridge

If the cartridge is clogged for some reason, it can accidentally activate the pressure switch. This can lead to cause the pump to not work although the system will show on.

Fixing it requires removing the cartridge from the system. To do it, remove the lid from the dock, and then remove the cartridge. Run the pump without the cartridge. If it does, you need to replace the cartridge. If it doesn’t, you may need to replace the entire system. 

Sensor Showing No Water

If there’s water but the sensor is showing no water, then there’s a good chance that the water has no mineral content.

To fix it, add a small amount of salt to the water. This will help the sensor detect that mineral is present in the water and will start working fine again.

Leaking from Dry-Break

This can happen when you’ve misplaced the dispenser. A poorly seated or disconnected dispenser can cause your Aquasana to leak.

Make sure that the vessel and the dock are fully connected. When you place the dock, you should hear a click.

O-Ring Issues

There are several o rings on your Aquasana. There’s one on the dispenser, another on the outside. Misaligning them or poorly fitting them can cause leaking.

If the dispenser vessel is missing an o ring, you need to replace the vessel. For the outer o ring, remove it and let it sit for 5 minutes to allow it to reform. Then reattach the o ring. If it still leaks, replace the o rings with newer ones.

Clogged Filter

If your Aquasana system is running on and off, then there’s something wrong with the pressure. The system’s pump will stop operating when the pressure reaches a range of 60 to 75 psi, which is possible if the system’s filter becomes obstructed.

To fix this, you need to replace the filter more frequently, especially if the water quality is particularly bad.

Frequently Asked Questions and Answers

How do I reset my Aquasana?

Use a pin to press and hold the reset button for 10 seconds. The Controller will display “rSt3”, “rSt2”, and “rSt1” sequentially, followed by a beep. You can now release the button, and it will be successfully reset.

Where is the reset button on Aquasana?

The reset button is located under the lid. It’s in the shape of a pinhole, so you need a pin to press it.

How do I clean my Aquasana filter?

Aquasana filters are not rated for reuse. So, if you notice a dirty filter, you should replace it with a new one.

Why is my Aquasana flashing red?

A blinking red LED indicates that your Aquasana filter has reached 90 percent or more of its capacity. When it reaches a solid red, you need to change the filter immediately. 

In Conclusion

Understanding how your Aquasana water filter works is crucial if you intend to extend its service life and want to enjoy a hassle-free user experience. Most of the time, a faulty installation or misconfiguration is what causes your Aquasana to not work. Sometimes, it’s just a maintenance issue like a worn-out filter or cartridge.
