We recently replaced our old washer with an LG Steam Washer 2487. When this new washer fills with water, it sucks water in intermittently at first, causing the water pipes to knock very loudly. Aside from cutting our wall open and fastening the pipes down do you have any other suggestions?

Re: 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.

I can tell you its not in the hoses, typically in the washer where the hoses go in there will be a screen. Check these screens, you will get a lot of sediment built up on these, i have to clean up mine every 2 years. This will still have to be done even if there is a water softener. If this is not the problem then I suggest checking every valve in the cold water system. Making sure they are opening fully.
The quick burst of water is normal for the LG washing machines, its the way the water valves work. The noise you hear, sounds like the water lines jerking, and hitting against the wall, or the cabinet itself. You may need to get some tape, and tape the lines to the unit itself.
Hiya .. your problem is more than likely to be one of two things
1. The element is overheating, which means the thermostat is not functioning as it should.. can you hear the thermostat Clicking? if so
2. No matter how soft your water area is.. there is always scale build up around and within the jets, try a good propietary descaler..... White vinegar is a good alternative.
Fill the iron with equal parts vinegar to water, and letting it steam until dry, rinse the tank with clean water, refill it and shake the water through the steam holes over a piece of newspaper/material... Test an old cloth before ironing on anything expensive. It should sort your prob ..... never advisable do this on a new iron as the acidity may damage the iron!
