This request might seem a bit simple 😯 but would be so helpful!
My wife didn’t recognise a white wingnut that fell out of our dishwasher and so chucked it 👿 ! It turned out to be what is needed to hold the arm in place on the upper tray for tall glasses etc
I have scoured for ages for this part and can’t seem to work out where to find it – then found your site with lots of successes. Is there anyway you might be able to help??????
