Mine also stopped spinning, I replaced the condensor which kicks starts the drum turning. Really easy to replace a couple of spade connectors and a 13mm nut to remove once back panel removed. Search for 'WHITE KNIGHT Tumble Dryer MOTOR CAPACITOR 8UF' on ebay they're about £4 sorted mine out hope this helps.
