How I sorted out the mid-tier vs premium dishwasher question - steps that actually worked

When I was looking at top-tier washers a couple of years ago, I spent way too much time looking at the advertised water efficiency ratings. I figured that was the main deciding factor, but my unit ended up shaking like a washing machine during the final spin cycle in the morning. Since I live on the third floor, that vibration was definitely going to annoy my downstairs neighbor. I decided to try a few brands just to feel the heft of the drum. The smaller, mid-range machines felt hollow when I pressed the front panel. The ones that cost a bit more just felt heavier and quieter even when running on the lowest spin setting. It wasn't a huge difference in price, but the sound reduction was noticible when running the heavy load of bedding. If you are concerned about noise, I think you need to look at the internal suspension rating, not just the Decibel rating. That's the part that holds the drum and keeps it from bouncing when the weight shifts. I learned that the more solid the build, the less movement you'll hear. It wasn't worth the headache of constant shaking.

One thing I'd add on the service question is to call the repair shop first, not the dealer. I found a local guy who actually stocks the common pumps and heating elements for the brand I bought, and that changed my thinking completley. On my old machine I waited three weeks for a part once, never again. Also ask about filter cleaning and wheather you can do it yourself without pulling the unit out. Mine takes two minutes from the front, and that alone sold me on the model I got.

Been running dishwashers since the days when they hooked to the kitchen faucet and you turned the tap on by hand, so take this for what it's worth. Something the spec sheets never cover is your water. If you've got hard water, ask the dealer what each machine uses to fight film on glassware. I keep the salt reservoir topped up on mine and my glasses come out clear again, no special cycle needed. One more thing on the price gap. When we bought ours, the dealer knocked a chunk off the floor display unit. Same warranty, couple scratches on the side nobody ever sees. Always worth asking before you pay full sticker.

Update: the tip about calling the repair shop instead of the dealer paid off. Found a guy two towns over who keeps pumps and elements on the shelf, and he talked me out of one model I had my heart set on. Still stuck on the hard water thing though. Does anyone know what you actually ask about film on glasses, just softener salts or somethig more?
