If you're running a fast-paced coffee business, slinging a high volume of milk-infused espresso drinks throughout the day, you'll be giving your commercial espresso machine's steam wands a serious workout. This results in some degradation of a few of its internal parts, which will require replacement in order to maintain full steam functionality. But performing this regular maintenance doesn't have to mean a tech call if you know your way around your machine's steam arm assembly. In fact, since performing this maintenance can be required sometimes as often as every 6 months, learning how to do it yourself will save you money, in addition to extending the life and performance of your machine. Sure, it sounds a bit daunting, but we're here to help! The first demonstration we have for you is on the Rancilio series of commercial espresso machines that feature their C-Lever functionality. We asked our commercial expert, Brandon, to guide us through how to remove, disassemble, replace parts, reassemble and then reinstall the steam arm on the Rancilio Classe 9, but this process applies to the majority of their machines. If you're starting to notice water or steam leaking from the wand when it's in its 'off' position, this is a hallmark sign that it's time to perform this maintenance. So watch this video and then dive in!
