Tried several new parts of our own choosing. None fixed the problem. Finally called Appliance Pros. Talked with representative Gaye Y. Explained the problem. She suggested checking the filter manifold for a leak. I didn't see any leak. but decided to get a new manifold and filter. Placed my order with ApplianncParts PROS. Parts came within two days. Parts installed and got water immediately. Thanks to this company & Gaye for her expert knowledge. She also sent videos that were very helpful in the installation.
Thank you, Gaye.
