This high pressure inlet hose washer is black. It is an inch in diameter, made of rubber, and used with many washing machines, refrigerators, and dishwashers.
Remove back side cardboard access cover. About 6 dcrews need to be removed. Remove 9/16” bolt and lower compressor tray frame down to slide out wheel axel. Place wheel in slot and replace axel. Lift compressor tray and replace 9/16” bolt. Replace cardboard cover. Remove 2x4.
Unhooked water line from house to fridge then unbolted valve from fridge body then removed plastic water line from fridge to valve by pushing in on pex release tab then reversed process with new valve. Works like a charm. No more leakage. Wood floor is dry and Happy!
Took lower back board off, took part off to expose it so I could see where it was leaking, got part number, ordered it. Shut off water to frig at wall shut off, unhooked both hoses and plug, hooked new part up, turned water back on. Watched couple days to make sure it wasn't leaking. Vacuumed out back good, which I was amazed didn't really need it, hooked part back in place, replaced back with screws.
