So I finally found an old top dishwasher rack at the Habitat for Humanity store. The rollers looked similar to mine and they said take the rack if it works okay and if it doesn't throw the rack away. The rollers did look much like mine in size and shape.
So I took one roller off. Now dishwashers they make these days are crap but try taking the thing apart.
When I put the new roller beside the old roller I thought there would be nothing to it. Wrong! I found the roller was too thick so I had to grind it down more than half. The hole for the shaft was too small so some reaming out took place. Then the screw that attaches the roller caught on the railing. So grind out a bit so the screw is inset.
And there you have it . A lot of work to alter a roller to make it fit.
And away goes my dish washer.
Now there are only two of us so we don't have a big pile of dishes. I do all the dishes. So around here it wouldn't be disaster if I didn't have dishwasher.
