Can HARD water, or Softened Water with salt pre-maturely corrode an aluminum spider in an LG SteamWasher?

THAT... is a VERY good question!

I would like to know because I have both a steam washer and softened water!

If the spider in your LG has been attached to the cylinder like mine(Horsey), Galvanic corrosion will occur with hard water, or water that has metal ions. Since cast Aluminum and Stainless steel are two metals to which when they touch are incompatible, the Aluminum will corrode when the two metals are placed in an electrolytic solution. In my case the Spider and the Cylinder were attached with nothing to separate them->extreme galvanic corrosion, when placed in either hard water,or soap solution.

Did any manufacturer consider this??????

What I find very interesting is that this sounds like something that was NOT thought of by washing machine manufacturers. I cannot understand why the spider is not made of stainless steel just like the washtub. Does anyone know why this is??? Is it a cost factor? If so, then cut cost some other way by adding less bells and whistles, and build a durable machine that will last at least ten years or more. However, I guess that would keep the consumer out of the appliance market if that were the case. I thought, just by looking at it, that the LG was a well built machine. But as the saying goes...................Never judge a book by it's cover.

SS SPIDERS

Would be prohibitively expensive and when you consider most spider failures are caused by gross misuse of the machine and thats not something manufactures test for or care much about. I don't see how one can consider that LG and Samsung are well made durable products when in fact they have no long term history of building high quality appliances and neither company has anything resembling a national service or parts distribution system in the US.

John,

What are the spiders in the Duet / Sears HE3 machines made of?

I bought one of the first HE3T pairs and have only done mega loads in it. Starting to wonder about the spider...

It has never let me down. I had to replace the front boot after about 4 years, but I think it was my fault that it failed. Easy repair. Did it myself.

Thanks
Brent

SPIDER MATERIAL

Hi Brent I have only seen cast alumium used when the tub is SS, on older front loaders where the tub was PE the spider was all welded steel and one piece with the tub.

What part of "planned obsolescence" do you not get? A spider made of metal that is designed to corrode over time is a perfect choice.

On the other side of the coin, I own an LG, and, as I've said before in many posts, to my untrained eye, this thing seems designed and built like machines from the sixties. I've used it as my daily driver for 7 years without a breakdown (knocking on Korean wood).I would imagine that a company like LG, trying to break into the US market, would want to make its first runs built well enough to make a good first impression. Almost all of the complaint against the company that I've heard are about its spectacularly poorly trained support/service network.
