Had a customer once who swore her dishwasher was haunted—turned out to be a rogue popcorn kernel wedged in the spray arm. Those things are sneaky. I’m with you on the vinegar trick, but I usually toss in a lemon slice too if I’ve got one lying around. Smells way better than just vinegar. And yeah, those impeller covers... I’ve seen ‘em put back upside down more times than I can count.
I've actually wondered if my dishwasher was possessed a couple times, mostly when it made that weird grinding noise. Turned out it was a stray olive pit (how it got in there, who knows) stuck in the filter. I’ll second the lemon trick—smells way better than vinegar alone, and I swear it helps with hard water spots too, though maybe that's just wishful thinking.
About those impeller covers, you’re not kidding. The design on some of these things is almost begging for people to put them back incorrectly. I had a Bosch model where the cover only fit one way, but it didn’t really *look* wrong if you flipped it. Ended up with a half-clean load and had to pull everything apart again. Not the most fun way to spend a Saturday afternoon.
I’m curious—has anyone tried those dishwasher cleaning tablets? I’ve stuck to vinegar and the occasional baking soda sprinkle, but the tablets seem like overkill unless you’ve got a serious grime problem. Also, I always wonder if they’re just a marketing thing or actually do something that vinegar doesn’t.
One thing I do every couple months is check the spray arms for gunk. You’d be surprised what ends up in there... bits of glass, toothpicks, even a twist tie once. Maybe I’m just unlucky, but it’s wild what people (kids especially) will throw in without thinking.
Anyway, I’ll keep experimenting, but so far the old-school methods seem to work best. Just takes a little patience and, sometimes, a flashlight and a pair of tweezers.
Getting That Stubborn Dishwasher Working Again Without Calling a Repair Guy
That impeller cover thing gets me every time. The one in my old Whirlpool looked like it belonged to a completely different appliance—had to watch a YouTube video just to figure out which way it was supposed to go back in. Missed it once and the dishes came out with that weird film, like they’d been washed in soup.
About the cleaning tablets, I’ve tried them out of curiosity. They do foam up and make things smell “fresh,” but honestly, I didn’t notice a huge difference compared to running a vinegar cycle. If you’ve got serious buildup or a musty smell, maybe they’re worth a shot, but for regular maintenance, vinegar and baking soda seem to do the trick. Plus, less plastic waste.
One thing I’d add—if you ever get a persistent grinding noise, check the chopper blade (if your model has one). I found a tiny piece of broken glass wedged in mine once. Getting it out was a pain, but way better than calling for repairs. And yeah, flashlights and tweezers are basically standard dishwasher tools at this point...
I get the appeal of vinegar and baking soda—definitely cheaper and less waste—but I’ve actually had mixed results with that combo. Sometimes it seemed to make the musty smell worse, almost like it just masked it for a day or two. The tablets felt gimmicky at first, but after a particularly nasty buildup, they actually cleared out some gunk I didn’t even know was there. Maybe it depends on water hardness or the specific dishwasher? Either way, I’m still not convinced there’s a one-size-fits-all solution...

You’re spot on about water hardness making a difference. I’ve seen dishwashers in hard water areas get mineral buildup that vinegar alone won’t touch. Tablets can help, but I’ve had luck with a manual clean—pulling out the filter, checking the spray arms for clogs, and wiping the door seals. It’s not glamorous, but sometimes elbow grease beats any chemical or tablet. That said, I wouldn’t write off the old-school methods entirely—just gotta match the fix to the problem.
