Freezing conditions can damage espresso machines by causing water expansion in confined systems, leading to cracks or leaks. This risk is heightened during winter moves or storage in unheated spaces. Improper handling, such as relying on wind chill or using unsuitable packaging, may exacerbate the problem. Users should avoid improvising solutions like dry ice or heaters, as these can further harm the equipment. Failure to follow manufacturer guidelines may void warranties and lead to costly repairs.
