If your fog machine is spitting liquid, it might be due to defective or cracked seals. If the fog machine pumps but no fog comes out, inspect the pump seals for fractures or corrosion. A faulty seal might allow air to enter the system, causing the fog juice to spit out.

In this article, we will be discussing why a fog machine spits liquid and related questions. Stick with us through the end and learn more about this topic.

Why is Your Fog Machine Spitting Liquid? | Repair Tips  

To ensure that fog machines continue to function correctly, they must be cleaned and maintained after each usage. In general, every fog machine will come with an instruction booklet that contains all of the cleaning and maintenance instructions for your specific device.

However, if your fog machine lacks an instruction manual or if you need more information on how to maintain your fog machine, you are in the right place. In this article, you will be informed about troubleshooting, maintenance, and safety tips to assist you in keeping your fog machine in good working condition. So stay tuned for more.

Common Fog Machine Issues and Fixes 

If your fog machine isn’t operating correctly, there are a few things you may do to fix it. If the fog machine pumps but produces little fog, see if the heater block is clogged.

Distilled water should be used to flush out the heater block. If the fog machine spits fluid, replace the seals.

If the machine is not working, check your electrical connections for any tripped breakers or damaged fuses. If required, reset any breakers and replace any fuses with fuses of the same rating.

Note: Before fixing or repairing your fog machine, disconnect it from the power socket to avoid electrocution. 

Tips for Maintaining a Fog Machine

Cleaning Your Fog Machine 

You must clean your fog machine after each usage to prevent it from being damaged during storage. This will also ensure that it is there for you the next time you require it.

Fogging fluids should not be left in the fog machine for a long time. Water should be used to clean the container until no fogging liquid or residue remains.

Clean the remaining parts of the fog machine.

Remove the detachable hose from your fog machine and rinse any fogging liquids that may be within.

Reattach the hose to the fog machine once it has been cleaned. Ensure that the liquid pump and its filters are clean. These may be found in the pesticide container, which can be accessed by removing the container.

If the fog machine has been sitting for a while, make sure the pump isn’t blocked.

Clean the exterior of the fog machine with a towel as well. This will assist you in inspecting the body of the fog machine for any signs of damage that may have occurred during operation.

Always empty and rinse the pesticide container to eliminate any fogging solution residue.

Turning Off Your Fog Machine

When you’re finished fogging, switch off the power before turning off the adjustment knob. Otherwise, certain fog machines may be damaged because the liquid might drop back through the hose and destroy the fog machine’s engine.

After you’ve turned off the adjustment knob, disconnect the fog machine. Other services to the fog machine should be performed only after these two stages have been completed for your safety and the machines.

Now And Then, Inspect Your Fog Machine.

Examine the fog machine for any signs of damage. Examine the fog machine’s critical components, such as power cable, fog juice bottle, and spray hose.

If you discover any damage to the fog machine, fix it per the instruction manual. You can also take the fog machine to a licensed servicing station.

How to Safely Store Your Fog Machine

You should keep your fog machine in a cool, dry location. Avoid keeping the fog machine in extreme hot or cold conditions.

If you’re going to store the fog machine for more than eight months, you should fog it a few times to ensure that the pump and nozzle aren’t blocked.

When storing the instrument for an extended period, make sure to preserve the nozzle of the fog machine. As previously stated, before storing the fog machine for an extended length of time, it must be well cleaned and thoroughly dried.

Any fogging solution should be removed from the container after each usage. However, any residual fogging solution must always be emptied from the container before long-term storage.

Any solution left in the tank might cause damage to the container and the pumping mechanism, rendering the fog machine inoperable.

Then carefully wash the empty container to ensure it is suitable for storage. Remember to completely dry the container before storing it to avoid corrosion on the tank or other elements of the fog machine.

How to Troubleshoot Your Fog Machine

If you notice low or no fog production and motor clutter, disconnect and stop using the machine immediately. Do not try to turn your fogger on and off, as this may cause harm to the equipment.

Determine whether or not the power supply is okay including all the fuses.

Also, check for a full reservoir of liquid as well as the remote control connection and the wall outlet. After confirming that these components are okay but still the fogger is malfunctioning, take your fogger to the service center for expert repair.

Do not attempt anything you are not sure of.

How to Replace a Faulty External Fuse in a Fogger

To begin, disconnect the power. The fuse holder is close to the power inlets. Unscrew the fuse holder with a screwdriver (flat or star head, depending on your model).

Replace the damaged fuse with a new one of the same rating.

Safety Tips  For  A Fog Machine

  • Unplug the main power source of your fog machine before connecting anything. Fog machines should always be placed in a location that provides for appropriate ventilation.
  • It’s important that you keep your power cord well out of the way of people walking by. In order to avoid being trodden on or pinched by anything put on or against them, power wires should be routed carefully.
  • Make sure that the voltage of the power outlet where you intend to use your fog machine is enough. Your fog machine’s top cover should never be removed. 
  • Turn off the main power to your fog machine when it is not in use for a long length of time. Using a dimmer pack with a fog machine is a bad idea. Never use your fog machine with the top off.
  • If your fog machine’s power line is damaged or broken, do not use it. Remove or break the ground prong from the electrical wire before attempting to do so. The prong is used in the case of an internal short to prevent electrical shock and fire.
  • No water or other liquids should be spilled into or onto your fogger. Make certain that the reservoir of fluid contains all of the fog fluid. Do not expose your fogger to rain or moisture in order to avoid the danger of electrical shock or fire.


Always read the operating instructions that come with your fog machine before using or servicing it. Check the fog machine before and after each use for signs of wear or damage. Inspect the fog machine’s pesticide container and hose for cracks.

Replace any damaged or broken components as soon as you notice them. As a last precaution, only use authentic manufacturer-recommended replacement components.

Finally, be sure to grease all moving parts on a regular basis to prevent corrosion and increase the fog machine’s lifespan. We always recommend cleaning your fog machine after a lot of use.
