There are a few things to check in case you notice this.   #### Is Excess Condensation Bad? Condensation is normal when it comes to brewing with your coffee maker. With that being said, there is a point where condensation can be excessive. Below are some of the things to look out for. 1. Check your Ratio Four's Filter Basket. 1. The filter basket should not rock when face-down on a flat surface. If the opening of the filter basket is rocking when face-down on the flat surface, this could mean the basket is warped, and should be replaced to prevent condensation from escaping the basket while brewing. 2. Descale your Ratio. 1. It's possible that if you don't descale often, or you have not descaled your machine at all, that this could produce excessive condensation. In these cases, be sure to descale monthly. 3. Ensure you're filling the water tank with cold/room temperature water only before brewing. 4. If you're not sure whether the condensation you're seeing collecting on your machine is normal, feel free to send our CX team at Ratio a video for us to review!   If you have any questions, please reach out to us at hello@ratiocoffee.com. - [Getting Started](https://help.ratiocoffee.com/getting-started?hsLang=en#main-content) - [Eight Series 2](https://help.ratiocoffee.com/getting-started?hsLang=en#eight-series-2) - [Six](https://help.ratiocoffee.com/getting-started?hsLang=en#six) - [Four](https://help.ratiocoffee.com/getting-started?hsLang=en#four) - [Eight Original](https://help.ratiocoffee.com/getting-started?hsLang=en#eight-original) - [Ratio Rewards](https://help.ratiocoffee.com/getting-started?hsLang=en#ratio-rewards) - [Coffee Guides & Education](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#main-content) - [Water](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#water) - [Grind](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#grind) - [Coffee](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#coffee) - [Grinders](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#grinders) - [Dose](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#dose) - [Maintenance](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#maintenance) - [Materials](https://help.ratiocoffee.com/coffee-guides-education-1?hsLang=en#materials) - [Maintenance](https://help.ratiocoffee.com/maintenance?hsLang=en#main-content) - [Cleaning](https://help.ratiocoffee.com/maintenance?hsLang=en#cleaning) - [Ratio Eight Series 2](https://help.ratiocoffee.com/maintenance?hsLang=en#ratio-eight-series-2) - [Ratio Eight Original](https://help.ratiocoffee.com/maintenance?hsLang=en#ratio-eight-original) - [Ratio Six](https://help.ratiocoffee.com/maintenance?hsLang=en#ratio-six) - [Ratio Four](https://help.ratiocoffee.com/maintenance?hsLang=en#ratio-four) - [Grinders](https://help.ratiocoffee.com/maintenance?hsLang=en#grinders) - [Warranty](https://help.ratiocoffee.com/warranty?hsLang=en) - [Returns](https://help.ratiocoffee.com/returns?hsLang=en) - [Troubleshooting](https://help.ratiocoffee.com/troubleshooting?hsLang=en#main-content) - [Eight Original](https://help.ratiocoffee.com/troubleshooting?hsLang=en#eight-original) - [Eight Series 2](https://help.ratiocoffee.com/troubleshooting?hsLang=en#eight-series-2) - [Ratio Six](https://help.ratiocoffee.com/troubleshooting?hsLang=en#ratio-six) - [Ratio Four](https://help.ratiocoffee.com/troubleshooting?hsLang=en#ratio-four) - [Accessories](https://help.ratiocoffee.com/troubleshooting?hsLang=en#accessories) - [Choosing the Right Ratio Machine](https://help.ratiocoffee.com/choosing-the-right-ratio-machine) - [Warranty Form](https://ratiocoffee.com/pages/warranty-request-form) - [Return Form](https://ratiocoffee.com/pages/return-request-form) [![Chill listening crop-3](https://help.ratiocoffee.com/hs-fs/hubfs/b8418dc3-0886-4e57-a609-b76b4a600d63.png?width=100&height=25&name=b8418dc3-0886-4e57-a609-b76b4a600d63.png "Chill listening crop-3")](https://ratiocoffee.com/) Help Center Copyright © 2026, Ratio
