The spiders problem doesn't have one cause. It's a series of things that together creates a time bomb.
1) Ridiculously low water levels (D.O.E.)
2) Poor quality materials (not exactly poor, but there is a ways to make it better, but it costs more)
3) Impossibility to make it cost more because consumers want as cheap as possible.
4) Millenials that think that just tossine 1 tide pod is enough. Because it has everything, right? it should perform amazingly well and we don't need to spend money on other additives.
5) Americans want everything fast, extremely fast, the washer must wash, dry, fold and put the clothes back in the closet in 3 minutes.
6) The bigger the better, so let's toss all the laundry, the cat, the dog, the husband, the kids, the mattress and the sofa all together in one load and select the quick cycle. If it doesn't come out clean or if it destroys the washer, let's blame the manufacturer because we're paying, so we can do whatever we want and the manufacturer will always be wrong.
7) Use only cold water. Hot water is so 1970's. we need to save the world and hug trees. Should be add some ice cubes and make a "wash on the rocks"? It doesn't matter if the final rinse drains like snot or if the clothes are dingy What matter is the washer using as little water as possible. and to mask the stench, we can add more fabric softener, more scent booster, spend more money buying odor or stain rescue pods, odor neutralizers, etc.
8) Let's keep the door closed after every use. Who cares if it will create the perfect environment for mold? We can sue the manufacturer if we had mold issues. This is 2018, the manufacturers should have created a way to prevent mold without changing our bad habits.
