So, how do you fix water flow issues with the Primo water dispenser?

Check and make sure the water line connectors are on tight. If they’re loose, tighten them gently. Ensure the temperature setting and control are turned to cold.

Ensure the water supply lines are installed snugly onto the faucet assembly. Remember to check your faucets for leaks as well.

Identifying and Fixing Common Problems With Your Primo Water Dispenser

Primo water dispensers are a great way to get more water into your daily routine. However, sometimes they have issues with the flow of water.

Here is how to fix these issues:

Micro Switch

The micro switch controls water flows from the main tank into the cup.

If this switch is damaged or broken, it will prevent water from coming out of your dispenser.

This can happen after years of use or if there is too much pressure in your home’s plumbing system (for example, when there’s a lot of water pressure).

To fix this issue, remove the lid on top of your dispenser and locate the micro switch near the bottom (it looks like a small black button).

Press down on it with a pen or screwdriver until you hear a click sound from inside the unit. Then turn off power at the breaker box and turn it back on after 10 minutes to see if that is fixed.

Gummed-up Water Diffuser

Check the diffuser plate if you notice your Primo dispenser has trouble flowing.

A clogged or gummed-up nozzle could restrict the water from flowing freely. Clean the diffuser plate using a toothbrush and warm soapy water.

Then, dry completely with a towel before reinserting it into your dispenser.

Kinked Hose

The hose on your Primo water dispenser should not kink easily. However, in this case, the water will not flow from the tank to the dispenser’s nozzle.

To fix this issue, after removing the hose from both ends, run warm soapy water through it before reconnecting.

Water Inlet Valve

Your Primo may have a faulty inlet valve due to wear and tear. This can cause poor flow rates when dispensing tap water into pitchers or other containers.

If this is the issue with your Primo’s internal components, replace the valve.


There may be something wrong with your filter if your water tastes funny or isn’t as clean as it used to be.

The filter may be clogged or damaged, blocking water flow from the dispenser. Clean the filter or replace it as needed.

Frozen Line

If your house is below freezing temperatures, ice may form on your Primo water dispenser’s line. This ice can prevent water from flowing into your dispenser.

Therefore, run warm water through the hose until it thaws out.

Water Dispenser Actuator

The actuator may be stuck or broken, causing problems with how much water comes out of your dispenser.

Clean the dispenser head with hot water and vinegar. If this doesn’t help, contact customer service for more help.

Water Flow Issues You May Encounter with Primo Dispenser

Primo’s water dispensers are designed to be easy and convenient for families. However, sometimes situations arise that can affect the machine’s functionality.

Here are some common issues that can occur and how to fix them:

Water Tastes Unpleasant

A dirty filter or reservoir can cause your water to taste bad. Take the filter out of the housing and soak it in warm soapy water for a few minutes. 

Then rinse under running water until all of the soap is gone. Dry thoroughly before replacing the filter in the dispenser.

After cleaning it, run it through a few cycles with water rather than the filtered one to remove any residue left behind.

If you’re still having trouble after doing this, double-check that the filter isn’t clogged up with dirt or debris. You may need to replace the filter if it is.

Enough Water Isn’t Pouring Out

Check that the water line is connected properly if you’re not getting enough water out of your Primo dispenser.

If this doesn’t help, ensure there aren’t any kinks or blockages in the line. 

You might also want to check if anything is blocking the spigot on top of the reservoir. If there is, remove it with caution and try again.

If these steps don’t help, call a technician for assistance.

You may want to check the float valve on top of your machine. If this valve is stuck shut, nothing will come out.

To fix this problem, ensure that no foreign objects (such as coins or paper clips) are stuck there. Then gently rock back and forth on the valve until it opens again.

Water Temperature Isn’t Right

Your Primo dispenser has an adjustable temperature control that allows you to select from hot or cold options. If the water temperature is too hot, it could cause burns. 

If it’s too cold, you’ll have a hard time cleaning. Check your Primo water dispenser temperature settings and make adjustments as needed.

What To Do if the Water Dispenser Leaks

If your water dispenser is leaking, there are a few things you can do to fix it;

  1. Let the air out of the water line by turning on the faucet with no dispenser attached. It’ll eliminate any bubbles that may have formed in the line and prevent them from escaping into your cup. As a result, the water line’s pressure will be reduced, preventing any more leaks. Although this sounds counterintuitive, it helps to prevent future leaks.
  2. Check the nozzle seal for looseness or damage. If loose, tighten it as best you can with a wrench or pliers. If damaged or worn out, replace it.
  3. Take technical issues into account. If sediments are in the water filter or you haven’t replaced it in a while, these factors may also contribute to leaky dispenser problems. 
  4. When you have tried everything, and the dispenser is still leaking, it may be due to the valve or something else inside your refrigerator. In this case, call Primo’s customer support to guide you on the next step. 

Keeping the Dispenser Clean to Avoid Problems

Your water dispenser is an investment and a lifelong companion as it provides clean and safe drinking water. However, it’s usually overlooked. 

Keeping your dispenser clean regularly increases its effectiveness, sanitizes it, removes mineral deposits, and allows you to get the best tasting water possible.

Think of water dispenser cleaning as an investment in your health. By cleaning it, you can be sure of consistently high-quality water in every glass.

It also ensures your home is a sanctuary, not just a place where you live.

Dirty appliances are breeding grounds for bacteria and can lead to problems with allergies and infections. When you clean your water dispenser, it will make the entire room look better and feel cleaner.

A clean dispenser will extend its life expectancy. You will also save money by not having to replace the parts that get dirty quickly.

Final Thoughts

Sometimes, no matter what you do, your Primo water dispenser won’t dispense any water. Yet, this article explains how to fix most issues with a few easy and practical steps.

So, if you experience such problems, follow those steps to fix the problem once and for all.

Hopefully, you can now troubleshoot these issues and get back to enjoying all the benefits of having a Primo water dispenser.
