One can only hope that will be common, but I get the feeling you may have been the exception to the rule because The Dealer would have called an appliance repairman anyway. I don't think any of the Dealers are prepared to deal with residential appliances, so unless they need to do a remove and replace I think you'll get referred to a local repairman.
I don't think you would get the same response for a slide motor or awning repair.
Maybe there is more to it than I'm reading.
