A simple google search will reveal several places offering spares for washing machines.
The PCB will be right at the top of the machine where no water can get to it - under the lid which you need to take off.
The PCB will probably have lots of connectors and you may be confused when you come to plug them back on to the new board - draw a connector map - mark up the connectors - take a digital photo - all three if you need the added confidence.
Do all this with the power disconnected.
You do not say the fault you have - sometimes you can repiar PCBs.
If for instance the motor is not turning it *might* be due to the final drive transistor usually mounted on a metal heat sink on the PCB - a new transistor might cost as much as £1.50. Three legs to unsolder - one screw to remove - New transistor with heat sink paste - put the screw back - replace PCB.
Control boards for domestic machines (boilers especially) are sold for Silly Money - a pcb might cost as much as £10 to make - usually a lot less - and sell for over £100.
Good luck...
