Re: servis washing machine
After that length of service, it could be motor-brushes, but you’d normally get erratic drum movements and “odd” sounding motor a while beforehand.
If the board is U/S you may have trouble sourcing one ,as i think Servis went bust a while since….you may be able to get a secondhand one from a scrapyard /appliance repairer/recycler/ site such as “freecycle”
Presume you already tried the “spares” facility linked on this site?
