Dishwasher Deodorizing


I spent a lot of time researching why our dishes smell like wet dog every so often. I was very glad to see the millions of hits I encountered as now I know I am not weird.

I think I may have solved it. After years of wondering about this I looked at everyone's answers and by process of elimination discarded anything that did not work or apply. I have two new Miele dishwashers and two new hot water tanks; therefore, it cant be the build up on the anodes. I have used all the good soaps, to no avail. Sometimes it is true that eggs will contribute to the smell, but then I should not have the smell if eggs were not used. I thought about chemical reactions with the well water, but then again people on municipal water have this problem. My water softener is new too with no odor to it. I wondered about chemical reactions during damper days, I added bleach, I added vinegar, baking soda, whatever I could. Sterilized the darn thing totally, removed the filters, cleaned out the bottom, checked the piping. Sometimes I would simply rewash the dishes using vinegar after the first pre-rinse cycle. The odd time I could still smell the darn dog.

So recently I decided to experiment again. I decided to add a little bit of vinegar to the machine after I unloaded it. Sure it would smell pretty strong for a while but then the smell would dissipate. Voila! For two weeks now my dishes have not smelled whatsoever. I am wondering whether or not the acid is neutralizing something in the bottom of the dishwasher which I normally can't access.

Anyways for all its worth. Try adding vinegar at the beginning of the day so that it can sit there until you turn the dishwasher on. I am very curious to see if this works for anyone else.

Something else that people recommend is putting lemonade flavor Kool-Aid in the dishwasher, and run it with no dishes. We do it, and it's nice and fresh! Only lemonade flavor will work, however. Anything else, and you'll end up with an unintended dye job in your dishwasher. X_X

Annie, I love your persistence and ingenuity. Your comments also gave me a good chuckle!

This is the absolute answer, you either have no "Air Gap" or vent off the garbage disposal drain outlet or the vent hose is kinked or the garbage disposal drain outlet is practically blocked with organic debris that creates the smell. We have tried all you mentioned and more and finally found the answer. First we added a air gap vent (the vent in top of the sink because I had a soap dispenser there before) which solved the problem completely then after that the problem re-occurred even with the air vent gap, we removed the outlet from the disposal and found onion skins lodged in the garbage disposal outlet. Removed them and problem solved again. Bottom line, add an air gap and check for debris. Problem solved. We struggled with this for over two years before finally solving the problem. I hope this helped. :) Best Wishes!

Eggs cause wet dog smell in my dishwasher. Prewash anything that has come in contact with either raw or cooked eggs before putting it in the dishwasher. I haven't had the smell since I figured this out.

Chris, you've certainly done a lot of work. Over my years of living, I've had at least 6 different water heaters, using at least 3 through their end of life. All but 1 heated city and village chlorinated water. I've never encountered smelly water as a by-product of a water heater.

I'm also on my 4th dishwasher ~ this is my 1st efficiency model and the 1st having a stainless steel tub and the 1st one encountering "the smell". And so, I consider the new design for energy efficiency the bottom line cause of the problem, and the likelihood of egg residue as a contributor to the stink. These efficient dishwashers are certainly poorly designed considering that users need to repeat cycles and add products in order to eliminate "the smell".

One stink required me to re-run a wash 5 times, using baking soda and vinegar and Dishwasher Magic to rid it. Leaving a bit of vinegar in the washer between washes has worked, but I wonder if the 'acid' bath will cause harm.

We are at our wits end too... we have had a Bosch in the South East of Uk and had the horrid pond smell on our dishes. We moved and re-installed the dishwasher in our newly refurbished home in the southwest. The smell persisted.

The dishwasher was ten years old but still going strong. We eliminated poor plumbing etc, we cleaned all pipes and filters. Still the smell of pond clung to our crockery and cutlery. We decided to get a new dishwasher as a last resort - a Kenwood. Argh, the smell is still there but is sometimes not... so we have to resort to washing dishes again.
We avoid putting anything eggy in the dishwasher.

I am at a loss and am so upset. It is embarrassing as the kitchen smells terrible sometimes and we can't have guests to dinner with this going on. Please can someone somewhere get to the bottom of this phenomenon? Please!

After the dishwasher is done, there seems to be a pond water smell on the dishes. I run the dishwasher 1 to 2 to times a day
