9.5.5 Cleaning the vent hole on the
pipe elbow
The pipe elbow is only accessible when the
steam cylinder is removed.
»
Remove the pipe elbow from the
back wall of the housing by
unscrewing the fixing screw of the
pipe elbow.
»
Check the small opening on the top
of the pipe elbow for dirt.

vent hole has a negative effect on the drain-
age process (see also chapter "Trouble
shooting" in the manual of the control).
