Preventative Maintenance & Cleaning Procedures - Espresso V3


Objective:
Preventative Maintenance (PM) is... preventative(!) and commonplace for all espresso machines regardless of make and model. Similar to changing the oil in your car. PM is comprised of replacing a dozen or so wearable components at key contact points and safety mechanisms to ensure your SLAYER Espresso Machine exceeds expectations day in and day out.  PM components (listed HERE) are wearable by nature and should be regarded as the first line of defense against requiring emergency technical support!

PM components are intended to be replaced annually on three, six, and twelve month intervals* and recommended (on the twelfth month) to be serviced by an experienced SLAYER trained technician. For a list of SLAYER technician references in your area: please contact support@slayerespresso.com or call 206 284 7171 (#1 in the Directory).

Additionally, maintaining your SLAYER results in great tasting espresso and unrivaled steam quality. Who could ask for more?!
