Replace the printed circuit board
When installing the printed circuit board with
housing (2) ensure that the vacuum hose (6) is
correctly pushed onto the connection (7). The
vacuum sensor on the printed circuit board
measures the vacuum in the suction system.
The control lamp lights up if the vacuum increases
(filter bag full). If the printed circuit board is
defective, it must be replaced together with the
housing (2).
