First, fill a dishwasher-safe bowl with one cup of white vinegar and place it on the bottom of the empty dishwasher. Set the dishwasher to run on a hot water cycle. The vinegar will break down any remaining bits of food, grease, soap scum, residue, and any other leftover grime.
The cause of this problem could be limescale or salt residues. If the residue can easily be wiped off with a finger, it is likely too much salt. If the residue is difficult to remove and comes off with vinegar, it is likely limescale (hard water build-up).
An easy way to prevent a smelly dishwasher is by regularly cleaning the inside of the machine. "We recommend cleaning your dishwasher every 30 days to help prevent the buildup of detergent and to ensure your dishwasher's running at its optimal performance," explains Lemmen.
Pour 2 cups (500 mL) of white vinegar into a glass measuring cup or other dishwasher-safe container and place upright in the lower rack. Run a normal cycle with the heat dry option turned off to clean the inside of your dishwasher. Do not use detergent.
Dirty Filter
To clean the filter, remove it from the machine (using the owner's manual instructions) and rinse it thoroughly under hot water. If there's a stuck-on gunk, soak it in hot, soapy water for several minutes and gently clean it with a soft brush before rinsing.
Take 1 cup of lemon juice in a container and place it on the bottom rack of the dishwasher. Next, you should run the dishwasher and watch as the citric acid removes all the calcium buildup. If there is still some deposit, you can use white vinegar as a rinsing agent to lift and remove the remaining deposits.
Depending on your water type, your dishwasher may be susceptible to hard water deposits or mineral buildup. Place a cup of lemon juice in your dishwasher's top rack or basket and run a normal cycle. The acidic lemon juice will work to remove hard water spots and iron buildup.
If you've noticed that your dishes have this issue, you can use lemon juice or vinegar to try and wipe it away. If the residue is as a result of hard water, then it will remove these stains; if it doesn't, then you may be dealing with detergent residue.
A mixture of equal parts baking soda and vinegar may unclog dishwasher drains. Pour the solution into the basket at the bottom and let it sit for 15 minutes. Then, pour hot water down the basket and run the rinse cycle.
Cohoon recommends a powdered mixture of washing soda, borax, salt, and citric acid powder. "Washing soda will obviously wash things up, while borax helps erase residue and remove baked-on stains and grime," she says.
Cold and abbreviated cycles cause sludge and slime buildup, he says. “[Buildup] doesn't hurt the dishwasher but defeats the purpose of using it to wash dishes, since nobody really wants to have dishes that have been cleaned in a slimy box,” he adds.
If you simultaneously put baking soda and vinegar in the dishwasher, the chemical reaction between the two ingredients can create a giant, bubbly mess. It's best to run a short cycle with vinegar and run a second, separate, short cycle with baking soda.
Run cycles with vinegar and baking soda separately. You can clean a dishwasher with vinegar and baking soda in a few simple steps, which include running a cycle first with white vinegar, then running a separate hot water cycle with baking soda.
To begin, you can clean a dishwasher with vinegar to eliminate the grime and odors. First, empty the dishwasher. Then put one cup of white vinegar in a dishwasher-safe bowl and place it on the top rack of the dishwasher. Run the hottest cycle on the dishwasher.
However, dishwashers don't last forever. The life expectancy of a dishwasher is about 10 years, according to manufacturers surveyed by Consumer Reports.
Brown residue found in your dishwasher is most likely caused by mineral deposits left after the water has evaporated. However, another possible cause for this is mould. Water with a high mineral content (hard water) can cause yellow and brown stains. Left untreated, this can build up on the inside of your dishwasher.
A white, milky film on glassware, dishware and the interior of the Dishwasher can be caused by phosphate-free dishwasher detergent. Detergents without phosphates can potentially leave a white film on glassware and other items, even the Dishwasher tub itself. This white film is most often observed in hard water areas.

Clean the dishwasher
Use hydrogen peroxide to clean out your dishwasher. You can spray hydrogen peroxide directly into the appliance, let sit a bit, then wipe out. Or you can create a cleaning “bomb” with hydrogen peroxide, baking soda and an essential oil. Mix them and use an ice cream scoop to scoop out round balls.
