Gaggenau Coffee System Not Brewing
Coffee System Not Brewing is usually one of a small number of specific, repairable causes — here's what to check and when it's worth calling a professional.
Common Causes
Mineral scale buildup
Hard water affects the brew group and internal lines the same way it affects any espresso machine.
A worn brew group or pump
The mechanical heart of the machine wears with regular use.
A clogged grinder or water line
Restricts flow and can affect both brewing and grinding performance.
Local conditions that matter here
In an Eichler a new water line cannot go under the floor, because there is no floor to go under — the slab carries the radiant heating loop, and cutting it turns a kitchen job into a heating job. Lines here run overhead or around the perimeter, which is why the same repair takes longer on one street than on the next.
