The Siemens connection kit WZ20310 does what he is: fastened with 5 screws on the lid of the washing machine Siemens, it provides a non-slip frame around a stacked thereon (Siemens) to secure dryer. A trim strip for front covers the frame then in the front view and also helps in the assembly to attach the frame accurately. What I did not like personally is that the frame is screwed directly into the cover of the washing machine. It is necessary to drill holes. If you one day but have more space and want to juxtapose the machine, the washing machine then these unsightly holes in the lid has. In addition, it exhibits evidence not clear which machines because now exactly 100% fit. From previous recessions, I gathered that it can at least give with third-party equipment problems. Speaking for myself, it fits perfectly with the iQ700 WM16S443 washing machine and the dryer iQ700 WT46W562. Supplied also are apparently only 4 screws there, but a matching 5 found safe in every household.
