In order to operate the switch, you need to align the guide located at the end of the on/off hose handle with the two small lugs on the socket.
By rotating the handle a quarter turn, the switch makes contact. Consequently, it doesn’t function properly.
However, if the hose is properly aligned but the switch still doesn’t work, try rotating the handle a quarter turn to the right. You will notice that the central unit engages normally. This indicates that either the hose or the switch is defective.
