Have seen all kind of possible repairs to the buillt-in vacuum not turning off - but came up with the simplest - unplug it!. It's plugged into a plug behind the wall and you can unplug it, then pull the plug out into the main part ot the basement and plug it into the basement outlet to use it. They said just bring it in to the service shop and they would replace it, but I couldn't get it out without 4 more hands.
