Hi,
 
I can’t find a replacement board online using the board number or the model number but perhaps you may be able to check a few things on the board itself.
 
The major black component marked brf ss 124dm shown in image 1 is a 24V relay which I suspect operates to connect power to the motor. Here are the [https://www.conrad.com/p/afe-brf-ss-124dm-pcb-relays-24-vdc-20-a-1-maker-1-pcs-1425174|specifications] for the relay which may be of some help.
 
Looking at image #1, did you test the fuse (F1 on board) with an Ohmmeter to maker sure that it is OK.
 
''Totally disconnect the power from the cleaner when testing with an Ohmmeter.''
 
Also see the image below where I have indicated what to me looks like suspect solder joints, that you may wish to check to ensure that they are not “dry” solder joints i.e. open circuit. Re-solder them if necessary.

Check that you can hear the relay operate (click) when you go to turn on the motor. If not, with the power totally disconnected test the relay coil using an Ohmmeter, (1600 Ohms).
 
Also test D14 (diode) and ZD11 (zener diode) to check that they are not open circuit. When testing diodes you may have to disconnect one leg from the board to get an accurate test (low resistance in one direction, very high resistance in the other direction)
 
If you can’t hear the relay operate and the relay coil testsand diodes test OK it may be a case of tracing the relay coil operate circuit to find out why it doesn’t operate when power is applied to the board. Slow process without a schematic ;-)
