Water supply line vibrates making very loud noise.
I have a Kenmoore Elite Quiet Guard 5, the water copper supply line from the valve under the sink to the dishwasher vibrates making a very loud noise. I have a hammer arresting valve under my sink that is supposed to eliminate vibration in the supply line that is caused by the solinoid on the dishwasher. I'm fairly certain that the water supply valve is secure inside the wall--it does not move when I pull/push on it.My thinking is that the problem lies in the dishwasher supply line somehow. Will replacing the copper supply line with a flexible stainless steel supply line reduce/eliminate vibration? Is vibration caused because the solinoid on the dishwasher is going bad?

Assuming the code is accurate the feed to the dishwasher is somehow blocked (or turned off), or the valve within the dishawasher is not opening properly. You need to first follow the supply line back to make sure there is not a valve that was accidentally turned off. The connection is usually made to the hot water supply pipe under the sink, and there is often a separate cutoff valve for the dishwasher. If the valve is open then the problem is within the dishwasher.
Turn off power to dishwasher at the breaker or fuse panel.Turn off water supply usually found under sink. Remove the front kick panel and remove water supply line from the valve,remove clamp to hose on dishwasher and remove hose. Remove electrical connectors from the inlet valve and remove screws holding valve to cabinet . Reverse steps to install. Slowly turn on water and listen and look for leaks if all is well turn on the power and start washing.
It all depends on what material your water line is made of and where you want to shut the water off at.
Under the dishwasher there is a threaded connection from the water line to the dishwasher and there is typically no isolation valve located there. You will have to follow the supply line back to where it ties in, typically it is feed from the kitchen sink water supply. Hopefully the plumber who installed the lines provided a local shut off valve under the sink, otherwise you will have to shut the water off at the main house supply.
Here is a couple of ways to cap the line off.
Copper - You can get a cap and solder it on, make sure there is no water in the line because it will not heat up enough for the solder to penetrate the joint. Use flux and lead free solder on the copper lines. When you are ready to replace, just turn the water off, cut the cap off, and install the necessary fittings to connect the dishwasher. If I was going to do this, I would install a valve and a braided stainless steel line for the dishwasher. This makes it a snap to reinstall. Any hardware store can supply these parts.
Plastic (PVC/CPCV) - same as above but use the proper cement rated for the type of plastic pipe.
PEX - You can buy a plug and a clamp ring, but you will need the proper crimping tool.
If you have a threaded connection, just go to the hardware store and buy a threaded cap.
If you need specific information, please update your question with more details, because I am just speculating what you have.
The water-inlet valve lets water enter the machine. First Check to see if the valve is getting water. Make sure it’s not clogged. There is a screen on the inside of the valve, this sometimes gets clogged up with debris. Check to see if you get power to valve when unit is put into operation may take a couple minutes to start a fill. If you have power and it’s not clogged up replace the valve .If you have no power to the water inlet valve check float switch. This can be done by checking the continuity. There is a video of this at www.appliancehelponline.com/servicemanual.html this will walk you checking the water inlet valve and the float switch. It may be a different model but the testing procedure will be the same. You can also enter your model # for diagrams and illustrations for most models.
You have too much water pressure it sounds like for the fill valve to operate properly. I am assuming it is chattering? How much water pressure do you have? If its too high an inexpensive regulator can be purchased at most plumbing supply stores to install in the DW supply line.
1. Locate the electrical service breaker for your appliance and turn it off at the breaker panel. If it is plugged in by a serivce outlet, unplug the unit.
2. Turn off the water source under the sink.
3. Disconnect the drain line under the sink.
4. Remove the lower panel under the dishwasher door.
5. Locate the small electrical junction box under the dishwasher and disconnect the wires leads. Remember, standard household wiring is as follows: BLACK (HOT - 110-120VAC), WHITE (NEUTRAL - 0VAC, GREEN (or bare copper) is GROUND. Make sure you reconnect the wires in this fashion with wire lug nuts. If you have a local outlet plug you may leave the wiring instact.
6. Locate the fill valve (Usually on the left hand side of the dishwasher). This is where the water supply line connects. Disconnect the water supply line from the fill valve.
7. The dishwasher should have a couple of mounting screws located where the top of the dishwasher cabinet meets the underside of the cabinet.
8. With everything removed, the dishwasher should now be free and slide out from under the cabinet.
Let me know if you have further questions. I hope this helps you.
NOTE: You can also remove the water supply line at the fitting under the sink if it makes things easier.
you an remove lower access panel run d/w and nextime it makes the noise grab a flashlight and take a look under. sounds like a vibration issue( especially since you hit it nad it stops) perhaps your copper water line is rattling or your drain line is hitting motor causing noise
