I'm trying to buy a new on/off switch for my Zanussi Turbodry WDT1085 and the site I'm buying from has several types, 'depending on the serial number'. I don't know where the serial number is, I have looked all over the machine and can't see one, can anyone help?

If it still has a rating plate it should be around the porthole door when you open it up.
Only genuine part number for an on/off switch on that model (all serial numbers) is 1245404007
