Why won't my wash domestic device put out...
Answers:    I assume it can still be removed. It is going to be far better to replace if you can find it. Just take it near you and have them contest it. I would try hardware supply, plumbing supply stores. If you cannot find it you will need a domestic device shop to make you a exotic one and that will be pretty pricey.
