This is a thing with every dishwasher I’ve had, some models seem better than other. You wash the dishes and when they dry, they have a musty odor I can only describe as “wet dog”. Other people often don’t seem to notice this, so maybe I am just sensitive to it. Though if I point it out, then they smell it.
I have tried:
- Cleaning every nook and cranny of the dishwasher and filter
- Running with orange kool-aid/citric acid/lemishine in dispenser after each wash (works decently well)
- Running a rinse w white vinegar after each cycle (this works the best so far)
- Making sure dishes air dry instead of dry inside the dishwasher (always do this, helps a bit)
In all instances where this happens, the dishes are clean and don’t have food stuck to them or floating around in the water.
Has anybody else fought this problem? What worked for you?

Oh oh, finally something I can comment on!
I’ve replaced a number of dishwashers and in every case like this the drain hose, under the dishwasher, had a low spot where water then mold collected.
It’s usually pretty easy to check. Most dishwashers are secured with a couple of screws to the counter top or sides. Once those are removed it should be easy to slide it out. Probably best to look up a YT video on it. But if that’s the problem the drain hose is a dime a dozen, don’t try and clean it. You’ll know if it’s the source of the smell pretty quickly.
Now this is a suggestion I haven’t heard before, thank you I will look into this!
This is so close to being right. You want your drain hose to have a high loop before it connects with the drain pipe. This site has more info and clear pictures.

Oh, I hadn’t heard of that. Of course that makes perfect sense though.
Saving this for future me with wet dog smelling dishwasher. Thanks for the tip!
This is awesome! So I get replace the hose, but then do you prop up the new one so there’s no low point for water to collect? Or will it just be an ongoing issue and need periodic replacement?
I can really depend on how the hose can be situated. Oftentimes the hose runs into a cabinet next to it and into the sink drain. Frequently just adjusting that under the sink is enough.
Also the hoses are intentionally too long so you can attach the hose before putting the washer under the cabinet. Making sure to take up the slack is the important part
But sometimes yeah you can’t and just have to replace the hose every once and a while. If you use the washer frequently enough, like at least once a week it should be fine for years
Sounds like we need a string tied to it attached to a lever!
Have you tried not using it to wash your dog?
Removed by mod
Have you checked to make sure the dog isn’t sneaking in?
Mm, yes, but have you considered that their natural habitat may be cold, dark, wet, and rotating? And in depriving them of that, are you not the true monster?
I have the same issue and eventually gave up and got whats called a “verfrisser” in Dutch. I suppose it translates to “refresher”? Its a little thing that hangs on the rack that keeps it smelling fresh. One is good for 60 washes, or 2 months. The one I have is made by “finish” and was €2 for 2.
My apartment also has extremely hard water so I also run it empty at max temperature with a descaling powder once a month. I find the smell is greatly reduced for a few days after descaling. That may be why youre smelling it less when using the vinegar rinse.
To help with smell in the washer we keep the liquid soap tray open after we finish using it. And leave the lid open most of the time. It seems to keep humidity down and the smell went away almost instantly.
Yes, open the dishwasher when it’s finished (like max 1h after)!
Works for me, and if I don’t well I get the smell.
I think this is a great preventative step. I have a side load washer and dryer and I have to keep the washer door open between loads. Other people I know got a similar machine and never did. Those machines smell like mold and they wash their clothes in it still. Eww.
Meanwhile I’ve had mine for 10 years and it is still working great. We run the clean cycle when it tells us, but the preventative step of “letting the water evaporate so mold doesn’t grow” is a great one.
Posting this as a top level comment as well for visibility.
The tablets are a scam.
Ridiculously detailed video about them here.
The TL;DW is: use powder over tablets, and fill both the main detergent section AND the prewash section (or just throw a little extra powder in loose)
Also, run the hot water before turning it on
replyIn Europe, appliances are never connected to the hit water circuit and are left to regulate temperatures by themselves.
Just fyi
Except for my mother in law. She hooked it up to the hot water to save gas (through solar thermal panels). In summer the hot water gets up to 70°C. So we need to shower first to lower the temperature again before she can start her dishwasher XD
I completely agree that powdered detergent is the best. Running the water to ensure it’s getting hot water immediately is also very important.
However, I disagree that the detergent should be filled all the way. The amount of detergent you use should scale based on water hardness. If you have softer water you can use less detergent. For example, I have relatively soft water where I live so I only fill the detergent about half way and my dishes come out sparkling. If my water was harder I’d have to use more. The instruction manual for the dishwasher should have guidance on how much detergent to use. Using too much can cause your dishes to not clean as well.
Yep, the video (or possibly the follow up video? don’t remember) goes into this. I’m in a very hard water area, so we fill it, but you’re right, it should depend on hardness.
Which incidentally, is another reason tablets suck.
Just a heads up, he debunked his own video later in the year. Turns out he overlooked a few small details that completely change everything.
Lol, did you watch the updated video? The only thing he got wrong really was that you don’t necessarily need to fill the dispenser, depending on how hard your water is. The rest of the advice remains the same.
Are you taking out the filter and removing all the food bits?
Yes. And I have experienced this on dishwashers that don’t have filters as well.

Splash the insides with vinegar, run it, toss in some baking soda, run it again.
And keep it at least partially open most of the time when not in use
I’ve had success with Jet Dry and Cascade Platinum plus pods. Our filter gets super gross after about 10 cycles. Between cleaning out the filter often and running those two product combos, we don’t really have a smelly washer. My other thought was your water quality. We have a whole house water softener. Have you tested to see if you have super hard water? This ruins appliances. Simple test can be bought on Amazon.
I’ve been wondering if it might be a water hardness/softness things. I’ve experienced this in several different cities, but it’s possible they all had either hard or soft water.
Those rinse cycle products are bad for you, so I’ve heard.
If your dishwasher has a musty odor it is harboring bacteria that will fuck up your mental health. I forget the name of the bacteria but it starts with an A and its airborne products can give you chronic inflammation.
That problem goes so much deeper than funky smelling dishes. It’s a threat to your health.
Same for any part of your home that produces this smell. It’s not to be taken lightly.
So what, nuke it and start over? How do we destroy the bacteria and still have the majority of our walls standing?!
Good info
Not a dishwasher, but may be related. I air dry my clothes indoors, sometimes overnight, and used to get that damp rag smell on my clothes as a result. Solution: toss in a tbs of baking soda - no more smell.
I don’t put certain things like dishes that contacted raw eggs in the dishwasher so that won’t happen. I’m still learning what the optimal way to use a dishwasher is though. This smell has a name in Arabic, زنخة (zanakha).
“I don’t put certain things like” . . . I expect you to say “dogs”.
Well you wouldn’t put a wet dog in the dishwasher, it’s already wet. I only put dry dogs in mine.
Wet dogs go in the dryer, hot dogs in the fridge
Wet dogs go in the dryer, and hot dogs in the fridge
I’m pretty sure my wife ran an empty cycle (no dishes, no detergent) with half a lemon in the cutlery basket. She seemed pretty happy with the outcome.
Run an empty cycle with a bunch of bleach.
lemons are great for this. You don’t need all of it, just the skin. press the lemon and enjoy the juice, put the skins on the glass rack and you’ll have a fresh lemon flavor when opening the door. needs replacing every other wash or so (they get hard and stop smelling)
Mine doesn’t smell, unless I’ve put an omelet pan in there. Egg just does not go away.
