Sounds like she had this issue before the sink replacement because she asked the plumber while he was there, and she wouldn’t be using the dishwasher when everything was disconnected while replacing the sink.

Check the filter, sounds like you haven’t cleaned it out before.
Maybe something plastic fell on the heater core and melted.
Check the vent filter on the pipes underneath your sink, replace it if you haven’t replaced it for a few years.

1-1/2 in. or 2 in. PVC Mini Vent Air Admittance Valve

Does the bad smell only come from the dishwasher (ie only when you open the dish washer). Or does it come from the general area of the dishwasher? If it’s the latter it may be from a faulty air admittance valve allowing sewer gas to enter your home. Another possibility could be the p-trap is being sucked dry due to improper plumbing , which might suggest you need an air admittance valve. Just a thought!

Is it possible a small animal got under the dishwasher and died? When we replumbed our utility room sink we ended up with two frogs in the house...

I always prewash my dishes so no chunks. I also add some baking soda and vinegar every now and then.

We’ve had a plumber to install a new sink and she checked all the pipes. I asked her specifically about the problem and she just shook her shoulders.

The dishwasher was brand new in August of 2024 and it’s been smelling since then. I bought a bottle of dishwasher cleaner and that didn’t help. I mean this smell is so bad it’ll make you sick!

Today I called the company that made it and she said they would have someone contact me.

In the meantime, I thought I would put it out to all of you - do you know anything that might help?

When my dishwasher smells which happens from time to time I pour bleach right inside and then run it. I don’t measure but it was about a half cup. Works every time.

sprinkle baking soda on the bottom of the dishwasher and place 1 cup vinegar on the top shelf. run reg cycle. also make sure no mold on inside door near gaskets.

I have exactly the same problem. Done all you have done & had a plumber take a look who almost got sick from the smell. Only thing I have found is to leave the door open just a bit preventing whatever it is from being sealed inside the dishwasher. Lmk if you find a solution. Good luck

I know what you are talking about. You must have a KitchenAid. I have been dealing with this issue for some time. For me nothing has solved the problem and KitchenAid is no help. Good luck!

I question if you have sewer gas backing in. Is your dishwasher connected above the sink P trap? If not that's your issue.

I had the same issue. I used the tablets you can buy to clean the dishwasher. Drop tablet in washer and run a cycle. Smells good now. There are tablets for your clothes washer too. Look in the aisle with cleaning products. Come in a small box usually with 4 or 6 tablets. Remember when shopping to look at top and bottom shelves.....amazing the stuff you find. To keep your stainless appliances "sparkling", wipe with baby oil.

Check the drain filter for something stuck. Also you can a run a cleaning cycle on sterilize (Very Hot Water) and this might help.

[coleprice]

Your Plumber was unqualified, lackadaisical and had a poor attitude. Any competent Plumber would have diagnosed and repaired the issue.

[DonnaNi4os]

Have you cleaned out the filter? Should be located in bottom. It twists out.

Is it possible that a little critter (mouse) died somewhere inside the dishwasher prior to you purchasing it, and the odor is noticed when it’s been used?
