Battery Powered Sprayer Not Working (4 Reasons)

Battery-powered sprayers are highly convenient and can save you a lot of trouble while spraying around your garden. 

But it can also end up as a trouble if it’s not working properly. So, how to fix battery powered sprayer not working issue?

To fix it, first, ensure that the trigger lock of the battery-powered sprayer is disengaged. Also, the nozzle should be turned ON. Use a fully charged battery to use the sprayer at its maximum capacity.

Clean up any debris or chemical residue in the nozzle. Then, test the battery connection using a multimeter. Finally, replace old, dead batteries if necessary. 

This is just a glimpse of the solution. In this guide, we’ll help you identify the underlying issues and fix them accordingly. 

Why Is My Battery Powered Sprayer Not Working?

Now, let’s take a quick look at the possible symptoms, their reasons, and the solutions for the different issues with the battery-powered sprayers:

Symptoms Reason Solution
Sprayer not spraying at full capacity Clogged Up Nozzle Clean the chemical residue and debris blocking the nozzle.
Battery Powered sprayer not starting Sprayer Battery Not Charging Ensure proper battery connection. Replace dead batteries.
Sprayer not pumping with the right pressure Pumping Issue Lower the sprayer wand beneath the tank.
The sprayer motor not running Issues with the sprayer Settings Check the trigger lock, and replace the batteries.

Reason 1: Clogged Sprayer Nozzle

Over time, the nozzle of the battery-powered sprayer will clog up with debris and chemical residue.

A clogged-up nozzle will struggle to spray out the chemical contents at maximum capacity. In the worst-case scenario, it’ll completely block the passage of the sprayer. 

Sometimes, foreign objects can enter the nozzle, blocking it up.

So, here’s what you should do if your battery-powered sprayer is clogged.

Remove and Clean the Nozzle

Clogs often accumulate in the nozzle, keeping the sprayer from dispensing the mixture.

Remove it and use a small brush or toothpick to clean out any debris. Soaking the nozzle in warm, soapy water can also help.

Flush the Wand and Hose

Disconnect the wand and run water through it to clear any blockages. Similarly, run water through the hose to ensure it’s not blocked.

Check the Feed Tube

Ensure the wand’s feed tube is fully inserted into the cap or sprayer. Incomplete insertion can cause clogs.

Use a Cleaning Solution

If water alone doesn’t work, try a cleaning solution designed for sprayers. These solutions soften the composition of the debris, making it easier to get rid of.

Caution: Be careful! Do not submerge the wand handle in the water. Only submerge the nozzle. 

Reason 2: Battery Issues

The most common issue faced by users with their powered sprayer is battery issues.

Batteries in sprayers are vulnerable to moisture and extreme temperatures. These factors can affect the battery life and cause charging problems. As a result, the sprayer won’t work.

If your sprayer’s battery is giving you trouble, follow these steps:

Check Connections

First, confirm that the battery is securely connected to the sprayer. Loose connections can prevent proper charging.

Also, your battery-powered sprayers won’t start if the battery is not securely connected to the sprayer.

Battery Health

Then, check the battery’s health. It’s because batteries degrade over time. Depending on the environment and external temperature, the lifespan of the battery can significantly decline. 

If your sprayer is older, consider getting a new battery and replacing the old one. 

Charging Environment

Just like battery lifespan, extreme temperatures can affect charging efficiency.

So, charge the battery in a suitable environment. Read the instruction manual provided with the battery-powered sprayer about proper storage.

When storing your battery-powered sprayer for extended durations, such as during winter, ensure to take out the batteries. If the batteries corrode within the wand during storage, you’ll have to get a replacement.

Charging Time

Adhere to the recommended charging time mentioned in the manual. Overcharging or undercharging can lead to issues.

Reason 3: Pressure Problems

Sometimes, the battery-powered sprayer wand pump will create a partial vacuum in the air-tight canister. This can end up causing the electric pump to stop pumping. 

Ortho battery-powered sprayer users mostly face such issues. 

Here’s what you should do if an Ortho battery-powered sprayer not working:

Check Pump Operation

Ensure the pump is functioning correctly. If it’s not building pressure, there might be a problem with the pump itself.

Inspect Seals and Gaskets

Regularly check the seals and gaskets for signs of wear or damage. Replace them as needed to maintain adequate pressure.

Detect Air Leaks

Inspect all connections for air leaks, even small ones. Air leaks can affect the pressure inside the canister, affecting the pump. 

Tighten or replace components to eliminate any air leaks.

Fix the Sprayer Pressure

Hold your Ortho Magic tank over the sprayer wand and hold the sprayer trigger. Then, let the gravity do its work!

Your Ortho Magic Wand battery-powered sprayer should start spraying again!

Reason 4: Motor Not Running

If you’re using Roundup battery-powered sprayers, you might face this issue. You may find that your sprayer motor is not running at all. Or, the sprayer won’t work despite the motor running. 

In that case, here’s what you should do for Roundup battery powered sprayer not working:

Disengage Trigger Lock

Trigger locks are a useful mechanism to stop the accidental triggering of the sprayer.

Disengage the trigger lock in your Roundup battery-powered sprayer and hold the trigger. You should hear the motor running again.

Charge the Battery

Ensure the battery is sufficiently charged. An insufficiently charged battery might not provide enough power to run the motor.

Use a multimeter to test the battery connection. Inspect the microswitch which activates by pressing the wand’s trigger.

If you’re dealing with dead battery issues, install new AA batteries for Roundup battery-powered sprayers. 

Check the Cap and Settings

Ensure the cap is correctly set, the knob is turned to “ON,” and the nozzle is adjusted to a spray pattern.

For Roundup battery-powered spray, slide the trigger lock on the handle to the “unlocked” position.

The pressure dial should be stable in any one of the settings. If it keeps turning without stopping, you need to replace it. 

Remove the Battery Tab

New Roundup battery-powered sprayer wands come with a battery tab. This battery tab works as a barrier for battery connection. 

Simply, pull it off before you start using your sprayer. 

Reprime the Sprayer

Re-prime the sprayer by engaging the trigger for up to 30 seconds until it begins to spray.

And that should be enough to fix your battery-powered sprayer issues! You can check this video to get an idea of how to fix Roundup sprayer:


Why is my sprayer pump not pressurizing?

The sprayer pump won’t pressurize due to a bad seal around the lid of the pump. The presence of debris on the check valve and leaks in the tank can also keep our sprayer pump from pressurizing. 

What is the pressure on a Roundup sprayer?

The pressure on a Roundup sprayer ranges between 25-150PSI depending on the piston pump pressure. The high-pressure piston pump can spray up to 150 PSI. On a low-pressure regulator, you’ll get a steady 25 PSI. 

How long does a battery sprayer last?

A typical battery-powered sprayer generally lasts 4-5 hours of continuous application on a single charge. On a single charge, you can spray up to 160 gallons of solutions.

Parting Words

That’s all the things you should do to troubleshoot battery powered sprayer not working.

Make sure that the sprayer is properly primed before using it. Clean the sprayer thoroughly after each use and store the sprayer in a cool, dry place. 

Avoid storing the sprayer with chemicals in it.

That’s all. Have a great day!
