The fresh brew unit [1] is driven by drive unit [2] with a 24Vdc motor 5 RPM [2.1]. On the output
shaft is a plastic connector [2.3] which drives the fresh brew unit [1]. A micro switch [2.5] controls the
position of the fresh brew unit.
The micro switch [2.5] detects if the fresh brew unit has started to turn after a coffee has been
selected or afterwards returned to its home position (home) position. An error E4 or E5 will occur when
something wrong is with one of the two detection positions.
