SSE18 Troubleshooting

We created this page to help customers with the most frequently occurring issues. Please take your time and read through the ones that sound similar to the issue you are having.

If your problem was not solved – please use the contact form below.

Semi-auto trigger response is slow
Please understand that the SSE-18 is an AEP, which means that it has a gearbox fitted into a very small form factor. It will always respond slower than a full-size AEG, due to the size limitation. (Smaller motor, smaller battery etc.)

If you feel like your SSE-18 is too slow for an AEP, it might be that there is oil on the contacts of your switch.
The oil can be cleaned off by switching the pistol to semi-auto and pulling the trigger 200-300 times. This process must be done in semi-auto and won’t work when the SSE-18 is on full auto.
The friction in the switch will wear off the oil, and in return, you should have a better trigger response.

Unfortunately, this is the only solution for improving the trigger response of the SSE-18.
Semi-auto shoots full auto
If your SSE-18 shoots Full-Auto when switched to Semi, then this is the right troubleshooting guide for you!

In most cases, this happens because the slide was closed with the fire selector in full-auto position. If this process is repeated multiple times or done forcefully, the cut-off lever is bent downwards, which causes it to malfunction. Please watch the video below to learn how to fix it.

Once fixed, please ensure to always close the slide with the fire selector on semi-auto.

Magazine is not holding BBs
If your SSE-18 magazine isn’t holding the BBs properly and causing them to spill out sometimes, then this is the right troubleshooting guide for you!

In the video below, Alex will explain how you can easily fix this issue. All you need is a Phillips screwdriver and a lighter. It can even be a nail file.

Unfortunately, we don’t have a better fix for this issue at the moment. Even if we send you a new magazine, this issue might occur again, therefore following the video guide is currently the only way to solve this problem for good.
We are working on resolving it and are doing our best to fix this for future batches. We thank you for your understanding!

Cable broke off components
Unfortunately, this can happen as the space in the SSE-18 is quite tight, and the cable must be cramped in there, in order to close it.

You can contact us and send in your SSE-18 to have it fixed.
However, this is the slowest and most inconvenient way, as you have to wait for the repair, as well as packing everything and bringing it to the post office.

This is why we recommend the following options:
(warranty will not be voided if it goes wrong)

1. Fix it yourself. If you have a soldering iron, and you know how to use it is probably the best way.

2. Ask a friend with a soldering iron. Anyone who works with electronics will have access to this tool, and it will take the person about a minute to get it fixed.

3. Visit a local electronics shop with a service center or an airsoft store. They will have a soldering iron. If they charge you for the service, please keep the invoice and send it to us. We will refund up to 20 EUR back onto your account. (It should be less than 10 EUR for this job usually)

If none of the above is an option for you, please contact us and attach a picture or video of the broken cable.

Battery doesn’t work
If you believe that your SSE-18 battery is faulty, first you have to find out whether it’s really the battery that is affected or if it’s just the SSE-18.

Please inspect that battery for damage. If you see that it’s the cable that broke off the battery – please refer to the troubleshooting guide for “Cable broke off components”.

Try a different battery in your SSE-18 if you have one. Should the gun be working after that, then you know that the battery was faulty.

If you have a different Lipo charger, please use it to find out if the included charger might be broken. If there is no red or green light visible when the charger is plugged in, it means that it’s broken.

In some cases, the battery can be fixed by plugging it into a dedicated Lipo charger.

If none of the above helped you – please contact us.
Muzzle Energy/fps are too low
The SSE-18 is an AEP which means that it has a small gearbox fitted into a tiny format. This is why the power of the SSE-18 is limited to under 0.5 Joules.

The power of the SSE-18 should be measured with 0.2g BBs, in order to get the right value for the speed. It should be between 190 fps and 230 fps.
If it’s not, please change the hop-up adjustment. More or less hop-up can affect the muzzle power of the SSE-18. Too much pressure and the BB can get stuck slightly in the bucking, which reduces the power of the gun. Too little hop-up and air pressure cannot be built behind the BB.

If this wasn’t helpful enough, please contact us directly and attach a picture of your chronograph readings to the message.
The gun is not working at all
In case you cannot pull back the trigger, the SSE-18 has a small black switch in the middle of the right side. Please move it upwards, in order to disable the safety.

If it still won’t fire, make sure to charge the battery with the included charger (light should be green) and establish that the battery is connected.
At this point, if it still won’t fire, please check whether any of the cables in the slide are broken off components.

Should you find any broken cables – please refer to the “cable is broken” thread in troubleshooting of the SSE-18.

If nothing of the above was helpful – please contact us.
Magazine release button came off
An issue with the SSE-18 might be that the spring which pushes the button back into the place – might jump out of its original position. This can happen if the button is pushed in too deeply.
Should you have lost the parts, you can find them in the SSE-18 spare part section at novritsch.com

Alex created a video for this issue. Please watch it to find out how to resolve this issue.

Hop-up doesn’t work properly
There can be multiple reasons for your hop-up not working regarding the SSE-18.
Please take off the slide from your SSE-18 and check whether you can move your hop-up dial. If this doesn’t move, then please take a Phillips screwdriver and unscrew the screw in the middle of the dial slightly. Now it should be easier.

If you can rotate the wheel three times by 360 degrees without encountering resistance, it means that you broke off the little pin from the hop-up plate.
This happens if you apply too much force on the wheel even though it’s already in its max. or min. positions.

Unfortunately, this is not covered by warranty as it’s a user error. Please have a look at the SSE-18 spare part section, in order to get a replacement part.
In case your issue is not covered in the points above
