Hi,
This hydrant already exists https://www.openstreetmap.org/node/1235873256. 

For adding new ones please use fire hydrant tags as described in https://wiki.openstreetmap.org/wiki/Tag:emergency%3Dfire_hydrant

In addition, with emergency=fire_hydrant you do not need the name tag, unless it has an explicit name see https://wiki.openstreetmap.org/wiki/Names

In Addition, Spanish names are usually not tagged as name in Germany. If there should be a Spanish name, there is name:es for it. https://wiki.openstreetmap.org/wiki/Names#Localization
