You need to check the switch - the incoming mains to one side of it - very probably blue & brown - the other wires to the motor on the other side of the switch - if there are more than two wires on the motor side then you'll have to guess or wait for the wiring diagram.

They usually have a buzzer - it buzzes when the two probes are connected and fails to buzz when they're not connected - short circuit (continuity) and open circuit (disconnected)
Draw a map of the switch contacts - use the buzzer to show connectivity between the switch terminals - operate the switch - use the buzzer to show the change.
With no buzzer (unlikely) use a resistance (ohms) range - big numbers = open circuit & small numbers (like zero) = short circuit. You can test this merely by touching the probes together.
