What to do if AGA Kitchen Appliances makes a hissing noise?
- MMrs. Traci MyersJul 29, 2025
If you hear a hissing noise from the back of your AGA Kitchen Appliances machine, even when the button is released (and it's not the usual carbonation hiss), it indicates a valve problem with the gas cylinder. Immediately leave the machine, without unscrewing the water bottle or gas cylinder. Open a window, wait at least 30 minutes, and then file a product complaint for the gas cylinder where you bought it or with the manufacturer.
