Question about LG Washing Machines

1 Answer

At the startup of every washing cycle the washer slams the water on and off and bangs around our pipes. I called in a plumber who said we could tear into the wall now or wait until a leak appears. No of our other appliances causes this problem. I want to know if there is anything you can do to the washing machine to stop slamming the pipes. Roy Stephenson 05/19/2011

Slamming of the pipes happens because of the water pressure and and the sudden opening of the water solenoid. The solenoid has to open suddenly as it is activated by a magnetic coil that pulls a plunger valve open. There is a spring (return spring) on the back of the plunger that compresses and gives the plunger a return power push to seat the plunger when the power is turned off. In the past few years, plumbers have been loosely connecting pipes in hangers so that they move with the change in water pressure so as not to bang and cause a noise that upsets the home owner. Also many homes are plumbed with plastic pipe that stops a lot of the pipe noise. Most washing machines and refrigerator ice makers that have water solenoids make some noise, but engineering has mitigated a lot of this with the return springs that have the strength to slow the action of the plunger in the solenoid, but yet open wide enough to allow full water inlet.

I suspect that your water pipes are not slung properly to mitigate the bang caused by sudden pressure drop, thus you most likely would get a pipe bang from any washers.You could try changing the solenoid in your washer on the premise that the return spring is weak, but this probably will not solve all of the problem. The banging is just upsetting and does no harm as it is a natural action.

You could test this out by hooking a garden hose to the water outlet at the washing machine and using a trigger release sprayer on the garden hose. When you trigger the garden hose, I suspect that you may hear a pipe bang.

What is causing the water lines to pulse enough to rattle the house piping when the washer starts filling?


This is known as "water hammer" noise or the result of an explosive rush of water moving through your pipes with such force that a shock wave is created and leads to a banging noise that repeats itself. Sometimes this is called plumbers knock. There is nothing you can do about that other than change the pressure externally to reduce the rush.

How to get rid of water pipe noise at home


This usually occurs with high water pressures.
It may help by installing a water reducing valve at the water meter.
When a dish washer or washing machine turns on and off the water you will get a water hammer noise. The pipe fixings have come loose over time and the pipe bangs against the fixings.
You can reduce this noise by installing a water hammer device on the all the taps and then connecting the hoses from the dishwasher and washing machines to the water hammer devices.

I suggest you check out the best options with a plumber.

Check your water pressure at the sourse. Strong water pressure will cause banging noises from relay valves open and close. Good luck and thanks for your question and I hope my suggestions help. burdfrenzy

Just recently, when the water valve that fills the washer closes, there is a loud bang. Otherwise, the washer works just fine. Is this a concern?


This is called water hammer. It is from AIR in the pipes - and the valve on the washer slamming shut.

There are devices that install into your pipes called hammer arrestors.

Check with a plumber to have them installed properly.

Washer bangs between wash cycle and first spin/rinse cyle


Sounds like you need a water hammer control in your Hot water line, usually it's teed into the line and is just a short length of pipe with a cap on it, acts like a shock absorber

Water Surge Making Pipes Knock


What you are describing is called "water hammering" and is caused when a water valve shuts off quickly. The momentum of the water moving within the pipe causes the pipe to bang when it comes to a sudden stop. Plumbers can install an air chamber to absorb the water hammer (just like a shock absorber) but you might try ones that you can just screw onto the hoses behind the washer. I have seen them at places like Home Depot in the plumbing department. (hope you can find someone who actually knows what you are talking about to help you find them) Alternately, you may be able to find them at a hardware store or appliance parts supplier.

it might need a new water pipe the old one could of been damage. and some washers dont let the washing machine work if the water pipe is damaged or broke. you might just need some knew 15 mill to 30 mill pipes depending on how big your water pipe is. if u get a plumber he would cut about 5 cm of the old pipe off were it is damaged and solder on a part of the new pipe to see if it works, if not he would take off the whole pipe and put another in if that doesnt even work he would recommend a new washing machine. if you were to get a plumber i would get a local one and self employed because if you live close to them they wont charge very much and they can get you a reasonable discount off a new washer and get you usually a 3 to 5 year guarantee on it.

Maytag Neptune model # mah6500aww: makes banging noise and causes machine to move


A loud banging sound in the pipes is usually caused by a water hammer effect. Water hammer sounds are caused by a valve closing in the system, and yet the water in the pipe is still flowing because of its kinetic energy. The banging happens as the water hits the valve that prevents it from going any further. If the kinetic energy is great enough, it can actually cause a pipe to burst or explode at the end. If a valve is closed near the beginning or in the middle of a system, the water keeps flowing after that point, and it can actually create a vacuum. This vacuum can cause a pipe to implode if the stress is too great. Roaring type noises may be coming from a spin bearing. This bearing probably had the grease washed from it because of a tub seal leak.
Squeaking sounds in a new washer are usually caused by the new parts getting broken in, and will usually go away after several washes.
The sounds of water gurgling, slurping, or sloshing during a spin cycle are usually caused by the drain pump pushing the water out of the washer tub.
Too much water pressure can cause a whistling or squealing sound. Adjust the hot and cold intake water valves to relieve this sound.
Metallic clinking sounds during spin or agitation may be the result of drive train components meshing during speed changes or after a pause.
Swishing or swooshing type of sounds may be caused by water and suds trapped between the tub and basket during a spin cycle, and will usually clear up as the water is drained from the washer
