Vacuum cleaner circuit not working, trying to understand why

Hello, i'm trying to understand why the circuit board of EV660 is not working correctly.

Basically when i push the ON/OFF button, no power is sent to the vacuum motor, because there is no voltage on the two connectors.

1. In picture 1 you can se the two orange pins/connectors going to the vacuum engine, to provide 22.5V DC and make it run.
2. I've tested the on/off switch for continuity on pins and i can measure that when you press it there is continuity between lines, but when it's not pressed, red and black line are not connected. The voltage between theese two lines is 24.51V DC, delivered by the battery pack underneath the circuit. In picture 1 you can see how the battery pack is charged, through the 4 wires on the right side, connecting to the wall charger.
3. Picture 3 is the battery pack and the missing voltage of 22.5V expected to power the vacuum engine.

What else can i check?
