Domestic dishwasher and washing machine inlet valves
Hi John, I don’t know where you got that picture number one I have never seen an inlet valve that looks anything like that on any domestic washer or dishwasher valve in the past 50 years.
Here is a picture of a three year-old KitchenAid dishwasher inlet valve, which is typical And is virtually identical to every other major brand, this valve is broken open because it froze this winter during a cold snap so you can see the diaphragm inside, you can also see the Robert Shaw name on the valve.
This valve came from one of our customers and we are in a hard water area. Typically, we see nothing in the screens , screens will not filter out minerals. Otherwise you could’ve just have a filter to filter out hard water. It just doesn’t work that way that’s why you use chemical water softeners to remove minerals.
