Why
The SodaStream Carbonator is typically made of Tritan copolyester or PET plastic, which can withstand moderate dishwasher heat but may warp or cloud under high heat or prolonged cycles. The lid contains a silicone gasket and a carbonating tube with metal components; the gasket can degrade and lose seal integrity, while the tube may corrode or clog. The manufacturer advises hand washing all parts except the bottle body, which is top-rack safe. Dishwasher detergent's alkalinity can cause clouding (etching) on plastic and accelerate gasket wear. Repeated machine washing can lead to permanent seal failure, leaks, and reduced carbonation efficiency.
How do you wash SodaStream Carbonator?
- Disassemble the carbonator: remove the lid, gasket, and carbonating tube.
- Hand wash the lid, gasket, and tube in warm soapy water using a soft sponge.
- Rinse all parts thoroughly with clean water to remove soap residue.
- For the bottle body, place it on the top rack of the dishwasher, away from heating elements.
- Use a gentle cycle with low heat and avoid high-temperature drying.
- Air dry all parts completely before reassembly.
- Reassemble the carbonator only when all components are fully dry.
What happens if you put SodaStream Carbonator in the dishwasher?
If you put the entire SodaStream Carbonator in the dishwasher, after one wash you may notice slight clouding on the plastic bottle and a looser fit of the lid gasket. After repeated washes, the gasket will harden and crack, causing CO2 leaks and poor carbonation. The carbonating tube may develop mineral deposits or corrosion, affecting performance. The bottle body may warp if exposed to high heat, leading to an improper seal with the lid. The damage is initially cosmetic but becomes functional: the carbonator will no longer hold pressure, rendering it unusable. Replacement parts may be needed.
Frequently asked questions
- What water temperature can the SodaStream Carbonator withstand?
- The bottle body can handle temperatures up to about 140°F (60°C) without warping. Avoid boiling water or dishwasher sanitize cycles.
- Will the plastic bottle cloud over time?
- Yes, especially if dishwashed repeatedly. The alkaline detergent etches the plastic surface, causing permanent cloudiness that does not affect function but looks unsightly.
- How often should the carbonator be replaced?
- SodaStream recommends replacing the carbonating bottle every 2-3 years or if you notice cracks, clouding, or seal issues. The gasket may need replacement sooner if it becomes loose.
