You say the motor does not work - and you also say that you can't switch it off - I assume a typo and that you can't switch it on.

I doubt that there's a PCB in the machine - there's a switch to select high speed or low speed - it will just change the arrangement of which windings in the motor are fed with power.

It is unlikely to be a brush problem - the general case is that you usually get warning of brush failure - the motor gets hot and smells. But no harm to inspect them is you can.

Given that a light on the machine has power then it would be sensible to trace with an appropriate test device just where the power is getting to - first check the input to the power switch - then check the output from it - then the same for the speed select switch. If you can see these switches operating by observing a change on the output then you might suspect the motor/brushes.

Another possibility is an open circuit wire - fallen off terminal - but that's very unlikely - why should a wire fall off?

There are some repair videos on YouTube

Good Luck...
