Troubleshooting a sparkling water maker is simpler than you'd think. You press the button, but the water stays flat or barely fizzy? Don't panic: in the vast majority of cases, the fix takes just a few minutes, with no repair needed.
Before considering replacing your machine, a few quick checks can pinpoint the source of the problem. This guide goes over the most common causes.
Follow this checklist carefully and your problem will be sorted out in no time.
Step 1 of sparkling water maker troubleshooting, check the cylinder
An empty cylinder no longer produces enough pressure to carbonate the water, even if the machine seems to be working normally.
Two signs don't lie.
The sound. A full cylinder makes a loud, sustained "pssht" when you press the button. If you hear little or no sound, the cylinder is probably empty or very low.
The weight. This is the most reliable method. Unscrew the cylinder from the machine and weigh it in your hand. A full 60-litre cylinder weighs about 1.2 kg, while an empty one weighs around 800 g. The difference is clear and easy to feel.
If you're still unsure, compare it with a cylinder you know is full, or use a kitchen scale. The difference between the two states is several hundred grams.
To better understand how long a cylinder typically lasts based on your usage, see the article How long does a 60-litre CO2 cylinder last. Note that CO2 cylinders sold in Canada are subject to Transport Canada regulations on the transport of dangerous goods, which ensures they're compliant and safe to use at home.
Step 2, make sure the cylinder is screwed in properly
The second step in good sparkling water maker troubleshooting is about how the cylinder is screwed in. A misaligned cylinder lets CO2 escape into the compartment instead of into the water. The result: the water stays flat even when the cylinder is full.
When you install your cylinder, two principles guide a proper setup.
- Screw it in straight: a cylinder that's slightly crooked won't form an airtight seal with the machine. Line the cylinder up straight, then start screwing it in gently
- Tighten by hand, firmly: the cylinder should be tight enough not to move, but don't force it with a tool. Screw until you feel clear resistance, then stop
If you hear a prolonged hissing sound after screwing it in, the threading is probably not aligned. Unscrew it completely, reposition the cylinder so it's straight, and screw it back in. The hissing should stop immediately.
For anyone whose cylinder is on its last litres, exploring the reusable CO2 cylinder sizes means having a refill ready the moment a problem comes up.
Step 3, check the seal
The seal is the small, flexible part, usually black, located at the base of the nozzle where the cylinder screws in. Over time and with use, it can wear out, dry out or shift out of place.
To check its condition, remove the cylinder and inspect the seal in good light. It should be flexible, properly seated and free of visible cracks. If you notice cracking, flattening or that it has shifted, it's time to replace it.
The seal is what keeps the CO2 from escaping. As the Canadian Centre for Occupational Health and Safety notes, pressurized CO2 cylinders should always be secured firmly in an upright position and protected from any damage to operate safely.
Most machines accept a standard replacement seal. You can also contact customer service to confirm the replacement part compatible with your model.
Checking the seal is one of the basic habits of sparkling water maker troubleshooting. It's often what separates a machine that lasts 5 years from one that lasts 10.
Step 4, check the bottle and how it's installed
The bottle plays a role in carbonation. If it isn't screwed in correctly or the water level is off, the machine won't be able to do its job.
Three important things to check.
- The water level: fill the bottle up to the indicated maximum line, without going over. Too much water keeps the CO2 from circulating properly; too little wastes the gas in the empty space
- Screwing in the bottle: turn the bottle until it clicks or reaches your machine's mechanical stop. A poorly screwed-in bottle can look in place without actually being so
- The condition of the bottle: a cracked or warped bottle, or one with damaged threading, must be replaced. Plastic bottles have a limited lifespan and eventually wear out, especially if they're often run through the dishwasher on very hot cycles

This grid covers most situations you'll run into when troubleshooting a sparkling water maker at home. If the problem persists after these checks, it may be an internal mechanical issue.
Step 5, contact customer service
The final level of sparkling water maker troubleshooting is to contact the manufacturer's customer service. If none of the at-home checks worked, don't force it.
Before writing or calling, have the following information on hand: the exact model of your machine, the cylinder size you use, a precise description of the problem and, ideally, a short video showing the issue.
This greatly speeds up the diagnosis and often resolves the situation without any product return.
Conclusion
Good sparkling water maker troubleshooting comes down to a few simple checks: an empty cylinder, improper screwing-in or a worn seal. A systematic checklist done in a few minutes is enough to get satisfying bubbles back.

FAQ
Where do you start troubleshooting a sparkling water maker that no longer makes bubbles?
Sparkling water maker troubleshooting always starts by checking the CO2 cylinder. Weigh it in your hand to confirm it isn't empty (a full cylinder weighs about 1.2 kg, an empty one around 800 g). Then unscrew it completely and screw it back in straight to make sure no gas is escaping. If the problem persists, inspect the seal visible at the base of the nozzle.
How can you tell if a cylinder is empty or just low?
The most reliable way is to weigh the cylinder in your hand. A full 60 L cylinder weighs about 1.2 kg, while an empty one is around 800 g. The difference is clear and easy to feel. By sound too: a full cylinder makes a sharp, sustained "pssht", while a low one gives a short, muffled sound that fades quickly.
What should you do if the machine hisses when you screw in the cylinder?
A prolonged hiss usually points to a misaligned cylinder or a worn seal. Unscrew the cylinder, check that the threading is clean and straight, then screw it back in gently while keeping the cylinder aligned. If the hissing persists after this, the seal likely needs replacing. A standard replacement part is offered by most manufacturers.
