Picture - WMF Coffee Machine Cleaning Instructions

WMF coffee machines’ intuitive touchscreen, automated functions and small footprints make these high-performance units valuable additions to any foodservice setting. Since proper care of essential equipment is important, these WMF coffee machine cleaning instructions will help you keep your unit safe and sanitary while also maximizing performance.

These instructions are applicable to the 1500S model.
