Our WMF 800 is now more than 1.5 years old, it is in daily office use with 5-10 brews and for the second time with defects for repair. Initially, we were quite impressed by the machine because it brews a drinkable coffee for a coffee machine compared to the portafilter. The machine is very maintenance-intensive, the Kaffeemuttreste are cumbersome to remove. We booked this as 'hobby'. After already 1 / 2year they had to service because the foam function was broken. Now the machine broke down in routine descaling. The descaling process could not be completed and launched always resist new. - Groundhog Day Marmot The WMF hotline initially works well, organized by WMF pick GLS lasted nearly a week. This is not up to date. The hotline our damage confirmed by phone as warranty claims. We have the machine settled our bill as a copy. After three weeks of processing time to WMF has deigned to provide an estimate about 225 Euro. This, despite the fact that the machine is still in the warranty period. Unfortunately, we must now confirm the unacceptable poor service services of other reviewers to WMF. Now we will have to argue with WMF on the assumption of costs. We can warn any potential customers just before WMF today.
