Removing the SodaStream bottle and CO₂ canister

First, check that there is no carbonation left in the CO₂ bottle. To do this, fill the 1-litre bottle with cold water up to the fill line, attach it to the unit, and press and hold the button on the top of the unit until there are no visible bubbles in the bottle. Once the bottle is decarbonated, hold the top of the unit and unscrew the CO₂ bottle. The bottle is now safe to be cleaned or replaced.

Next, you will need to remove the CO₂ canister. This process will vary depending on the model of your SodaStream, but it will generally involve removing screws and covers to access the canister. For example, to remove the canister from the SodaStream Source model, you will need to remove four 17.8 mm screws from the bottom metal base using a Phillips #1 screwdriver. Then, pull the outer cover away from the front of the device, and remove two 18.2 mm screws from the bottom of the front cover, again using a Phillips #1 screwdriver. Finally, firmly pull the front cover off to access the CO₂ canister.

It is important to note that you should never use hot water to wash your plastic SodaStream bottles, as this can compromise the structural integrity of the bottle and weaken it, making it unable to handle the pressure of the CO₂ gas.

Disassembling the device

To begin disassembling your SodaStream device, place it on a flat, sturdy surface in an upright position. Ensure that there is no carbonating bottle inside the machine. If there is, remove it. Never insert or replace the cylinder while a carbonating bottle is in the SodaStream.

Next, remove the back cover by gently pulling it away from the body of the device. While doing this, place one hand on top of the SodaStream to stabilise it. Once the back cover is removed, you will have access to the carbonating cylinder.

Now, raise the cylinder handle and take out the empty cylinder. If you are replacing the cylinder, remove the seal and cap from the new SodaStream Quick Connect Cylinder.

After that, you can insert the new cylinder into the cylinder holder. Position the bottom of the cylinder into the holder first, and then gently place the rest of the cylinder into the holder.

Finally, replace the back cover by fitting the upright tab at the bottom into the rear slot at the base of the SodaStream. Push the cover into place, and you're done!

Removing the plastic arm

To remove the plastic arm, start by unhooking the bottom piece of the plastic arm on each side of the SodaStream device. Next, use a spudger to lift and remove the top of the plastic arm on both sides. Then, using a plastic opening tool or nylon spudger, remove the plastic piece located near the front of the carbonating block on both sides of the device. This will help you access the internal components of the SodaStream and allow for further disassembly or repairs if needed.

It is important to be gentle and careful during this process to avoid damaging any other parts of the machine. Additionally, having a basic understanding of the SodaStream's internal mechanisms can be helpful when attempting any repairs or replacements. It is also recommended to consult official guides or seek assistance from authorised service personnel if you are unsure about any steps or procedures.

The plastic arm in a SodaStream is an essential component that contributes to the overall functionality of the device. By following these steps, you can carefully remove the plastic arm, allowing you to access other internal parts for maintenance or replacement.

Additionally, it is worth noting that proper maintenance and care of your SodaStream device can help extend its lifespan and reduce the need for frequent repairs or replacements. Regular cleaning, for example, can help prevent the buildup of dirt and dust, ensuring that your SodaStream functions optimally.
