Banging pipes when washing machine fills

Hi.  We recently installed a new LG steam washing machine.  When the drum is filling with water, the pipes in the wall bang so loudly that it sounds like they will burst right through the wall.  Any idea why this is happening, and what we can do about it?  thanks so much.

It is called water hammer and is difficult to cure. try turning tap off halfway. another cure but difficult and not 100% is to take the copper feed pipe round in a circle

Loud banging noise when filling


Most likely a water hammer noise in your water pipes. Probably not your washer. Google water hammer.

When machine operating the pipework throughout the house makes spasmodic banging noise.


Hi, when the washer fills, its calling for water from your supply lines. The banging of your pipes happens everytime it fills. It is a plumbing problem. Need to have a riser installed in the water line which will correct the problem. Thanks

Either a main control board or you have a drain line problem causing the water to siphon out. If you house drain is lower than the washer water fill line or if your drain hose is sealed into the house drain line then you can have the water siphoned out of your washer. Check to make sure the drain line is not to far into your house drain pipe and that there is air around the drain hose where it enters the drain pipe, (not sealed tightley). If it is not the drain siphoning then you need a technician to diagnose the main control board and to replace it. Good Luck Appliance Specialists

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.

We replaced our old wash machine with a front loading LG Steam Washer 2487. When the machine initially fills, it sucks water in short, sharp bursts, which is making our pipe bang loudly. Short of cutting...


This is called water hammer - and is caused from AIR in your pipes.

There are Hammer Arrestors made to eliminate (or lessen) the hammering.

You should also bleed the air from the pipes - and re-prime them.

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.

Water gets drained automatically without fills the water


HI there. You drain out pipe need to have a kink and the kink need to be higher than the highest point of when the machine is filled with water or else gravity will let the water drain out as you fill it up. HOpe it works.
