If it needs more than new plugs , most of the Viking dealers in the Jo Anns stores sends machines back to the factory for any major repair ( anything other than a routine cleaning) ... and it will be awhile before you get it back. Do ask if they are sending it back how long before you can get it back .. if its longer than you can tolerate see if there is a Viking dealer in your area that can handle a bigger repair with out shipping back to the factory.
