I have an in sink garbage disposal unit made by Kitchen Aid. Model KWS-200,Magnestart-with a magnetic plug. This plug has broken so I can no longer fill the sink with water or turn it on safely as the magnet part falls straight down the hole. I would like to order a new plug, but am unable to find contact for Kitchen Aid supplier. Could you please advise me if they are still around or if there is some other supplier or distributor I could contact. Thankyou. Louise Davey.
