I have a broken Kenmore 587733301 a half size dishwasher unit from quite some time ago.
Of course the part that broke is one of the only ones no one has. So is JB weld safe for use inside a dishwasher? LOL
Unless anyone has another idea I feel like a dime of JB weld and this thing will be good for another forty years. Thanks for looking!
