We got a new dishwasher about a year and a half ago, after our old one gave up the ghost and refused to distribute soap anymore (plus I think it was older than I am, so it had fulfilled it's useful life span long before we even got here). I love having a dishwasher. This is the first place I've lived (since leaving my parents' home) with a dishwasher, and I can't tell you the hours it has freed up in my day. It disturbs me that I have been given all these extra hours, but oddly, don't have any particular accomplishments to account for them.
I like the one we bought, and it's really efficient - it uses only about 5 gallons of water for the whole cycle. However, it has recently started grumbling at me. It started as a once in a while thing - like someone being just slightly annoyed and then leaving the room. In the last couple of days it has turned into a full-fledged angry fight about 5 minutes after it's turned on.
Hmmmm....I'm not a particularly handy person, but my dad is, so I gave him a call. He suggested taking off the sprayer arm and checking to see if anything was caught. Sounded good, so this morning I emptied it out, took out the lower basket, and realized that my spray arm is completely smooth on top. No convenient little bolt holding it into place that I could unscrew and thus remove said spray arm. I examined it a bit more, and discovered that the mechanism seemed to be threaded, and could be lifted, twisted, and then removed. I was so excited to have made this earth-shattering discovery, but was promptly disappointed to find nothing stuck in there which could account for my clearly angry dishwasher.
Off to Google (I love Google) rumbling noise in the dishwasher. It's amazing how specific you can get in your questions to find an answer. Lots of people seemed to have this problem with GE dishwashers, and the fix seemed silly. It involved only a twist-tie. It was easy. Can't possibly work.
Well, one twist-tie later, and my dishwasher is now my quiet, uncomplaining and faithful companion once again. Welcome back old friend.
