I'm in the process of replacing my dishwasher but I have a problem. I followed the water line from the dishwasher to under my sink and found a red valve that was completely straight, so I turned it to the right as tight as it would go and tried removing the hex nut connecting the line to the dishwasher. Maybe i'm wrong, but there is a lot of water coming out of the line and I don't think it's supposed to. I easily filled up a bowl you would use to mix cakes and it was still going! So, I turned the valve back to straight across thinking maybe someone else turned it off (my dad), and tried it again but the same thing? What am I doing wrong and what should I do to solve this?
If you have cut off valves below water lines going to the dish washer,turn them off. There should be a hot and cold water line. Red is used to designate the hot water line and blue for the cold water line. If all else fails,turn the water off at the water meter,this turns off the water to the whole house.
If it is a quarter turn valve , the lever should be across ed the valve ,not in line with it. If that's not working for ya, turn the main water valve off. then drain the water pressure by opening the faucet at the highest point and the lowest point in the house. now it's time to change the dish washer. Good luck it shouldn't be that hard.
Sometimes the valves under the sink can't completely stop the water flow or they,ll stop the flow only to leak once they are opened up again after the repair. The way around this is to turn off the water to the house. You can do this by locating the water inlet valve usually located in front where your garden hose is toward the bottom you'll see a valve close it off to stop the water. Once you have done this turn on the kitchen faucet and the bathroom faucet to help drain the system and to insure you have shut off the water, replace the dish washer then slowly turn back on the water to remove any air in the lines then close the faucets.
either replace the valve or just turn water off at street remember being the lowest point of water service in your house once you turn it off at street or cut off all the water higher will travel to that point
