Tip & How-To about Dishwashers

Clean a Dishwasher

How To Clean A Dishwasher

  1. Using a small brush (old toothbrushes work well) dipped in hot water and white viniger, go around the door of the dishwasher taking care to get into the grooves and crevices of the rubber seal. Most likely, you'll be surprised at the debris that has built up, especially at the bottom of the door and around the hinges on the side.
  2. Pull the bottom rack out and examine the drain area. Wipe around it to be sure there are no hard chunks that can plug the drain, cause damage to the pump or scratch dishes. You'd be surprised at what dishwasher repairmen find - bones, crab shells, chips of glass, and even small pieces of gravel!
  3. Using a clean wet sponge or dishrag, wipe the cleaning solution from the gasket and the door.
  4. Then place a dishwasher-safe cup filled with plain white vinegar on the top rack of the dishwasher. Using the hottest water available, run the dishwasher through a cycle - except for the cup of vinegar, the dishwasher needs to be empty.
  5. The vinegar will help to wash away the loose, greasy grime, sanitizes, and helps remove the musty odor.
  6. Baking soda is also effective at freshening and brightening your dishwasher. Just sprinkle a cupful around the bottom of the tub and run it through a short but complete cycle using the hottest water. Baking soda is also helpful in removing stains.

I have the Bosch Next 500 series and I hate it. I am trying to clean off the mold growing on the 'roof' of the detergent basket. I am using a dental tool and q tips but I can't reach some of it.


Hello. Welcome to a "nature of the beast" situation with cleaning your washer. These washers are a lot more user intensive than the older ones. I'm a tech and tell all my customers to build a CLEANING KIT consisting of the following:
2-gallon bucket
2 old toothbrushes
1 kitchen or bathroom scrub brush(on the medium/small side)
3 old wash cloths
3 pairs of comfortable rubber(Playtex) gloves
1 gallon of household bleach
Procedure: Put on gloves(always)
MIX 1 cup bleach to 1 gallon of warm/hot water
Clean the dispenser areas with the toothbrushes dipped in the water/bleach solution(be careful to *not* get bleach on any metal surfaces, use the scrub brush also. Try to flush the areas with clean water or wipe/flush with a wash cloth and clean water.
FOR CLEANING THE BELLOW(RUBBER BOOT THAT MAKES THE DOOR SEAL)
Dunk a wash cloth or 2 in the water/bleach solution, squeeze out enough water so that the cloth is very wet but *not* dripping, carefully place the cloths in the fold of the bellow and wipe around and around, repeating the dunking and squeezing as often as needed. DON'T BE ROUGH, DO NOT USE DENTAL TOOLS ANYWHERE NEAR THE BELLOW--if you puncture it, it will leak and have to be replaced. You can use a toothbrush or scrub brush as long as you are gentle with the scrubbing. Take your time and try to remove as much of the mold as possible.
Run a washer cleaner through the unit at least once per month. For heavy mold build-up you will have to use several boxes of cleaner once a week for 3 weeks. After each cleaning cycle(no spin needed), run the washer on HOT WATER, heavy duty, bulky, etc WITH NOTHING IN IT), then, for run #3, only wash whites--this will ensure that anything with cleaner in it has been flushed out the washer. I hope I helped you!

dishwasher does not clean dishes anymore is there anything i can do to fix this


Your spray arms are probably clogged. The clog may be caused by grease or scum OR it could be from bits of debris that has not been flushed from the machine.Generally, the lower spray arm is easily removed by unscrewing a nut or thumb screw on the top of the arm. The arm will lift off easily and you can flush it at your kitchen sink. I sometimes have to take a toothpick, a brush, and/or tweezers to remove bits of paper, bone, or peelings. You can also soak it in ammonia to cut the grease that may have built up inside it.
Then put it in place and rescrew the nut or screw.This should restore the water pressure.

Also, be sure your water temperature is hot enough to dissolve the dishwashing detergent if you use a powder detergent.
And one last thing, check the underside of the door on the INSIDE of the machine. There can be a HORRIBLE build up of "crud" that you can't see when the door is open. Use an old toothbrush to clean the area. It also helps to run a cycle when the dishwasher is empty of items. Use about 1/2 cup of white vinegar and your hot water cycle. This will help clean the build up of chemicals inside the machine.
I hope this helps. If it does, please come back to Fixya and rate my solution

I own a GE Profile Trition quietpower III GSD5940F00SS dishwasher. The dishes, particularly the mugs and cups, are not getting clean.


Your sprayer arms may be clogged. You can remove them by loosening the screws holding them in place. Flush them with the sprayer at your sink. If you can SEE residue (parts of paper labels, bone fragments, fruit peel pieces, etc) remove them with a tweezer.Reinstall the spray arms and see if that works.
Three more ideas:
(1) run a cycle without dishes OR detergent and use 1/4 cup of white vinegar instead. This will break down soil and "gunk" and help your dishwasher run more effectively.
(2) use an old toothbrush and clean the underside of the door INSIDE the dishwasher. The door will be open and you just brush the bottom of the open door on the INSIDE of the dishwasher. A lot of "crud" gathers there and can be redeposite on your dishes. We seldom think to check that area.
(3) the pipe that carries water to the upper sprayer arm MUST fit against the outlet in the back of the dishwasher. If it is dislodged or not seated properly, the water won't flow to the upper sprayer arm.
Hope one of these suggestions helps. If it does, please rate my suggestion. Thanks.
