Dingy Dishes
October 23, 2007 by Heather
Dear Home Ec 101:
My dishwasher just isn’t doing as great a job anymore. I haven’t changed anything: same soap, I scrape the plates, I still use a rinsing agent. What could be going on?
Signed,
My Dishwasher is a Dud

Did you know your dishwasher requires regular maintenance to provide consistently clean dishes?
- Check the trap for food particles. If food scraps have crusted onto the trap, remove it, soak it, and scrub it. Make it a point to regularly check and clean the trap.
- Examine the spray arm. Are the holes clogged with mineral deposits? Soak the arm in diluted vinegar and use a pipe cleaner aka chenille stem to clean out any gunk.
- Take a good look at the racks, are they clean or has the paint worn off in places? You can purchase dishwasher repair kits that contain vinyl paint and those tips that always seem to pop off the prongs.
- Occasionally, once a month or so, run the dishwasher through a full cycle with 2 cups of vinegar. Start the dishwasher, wait until it has filled, and add the vinegar.
- Alternately you can run a cycle with citric acid or lemonade kool-aid packets, the kind that does not already contain sugar
- Finally be sure your hot water heater is set to the temperature recommended by the dishwasher manufacturer. If you have lost your manual try Googling the model; many manufacturers now have manuals available online.

How do you add something once the dishwasher has filled up?
This sounds so basic but I never even thought about it! I thought the dishwasher was magical and didn’t need maintenance..hence I’m a guy with dirty glasses
I just use a packet of unsweetened lemonade Kool-aid powder (almost pure citric acid) in each of the detergent compartments and run a cycle through. That way I can start it and walk away.
To add the vinegar, just start the dishwasher and listen. There should be two noises, one is the filling noise which precedes the noisier wash cycle. When it just begins the wash, carefully open the door and add the vinegar.
They do sell citric acid, but I can’t remember where to buy it off hand. I have heard of using kool-aid, but I have never tried it.
Heather, can you do a write up on how to properly fill up a dishwasher? I always have trouble decided how to put the dishes and bowls. Can you use up every single slot? I always think that the water won’t get inbetween the dishes if I set the plates next to each other.
Great post, Heather. As an ex appliance tech I wanted to point out a couple of things. 1. Two cups of vinegar is probably not enough. You may want to use a gallon instead. 2. And, it’s not a good idea to add any more liquid once the dishwasher has filled with water. Dishwasher has a float that controls the amount of water it takes in, so it would be better to dump the vinegar in the tub first, then let the dishwasher fill with water. It might get a little tricky because some dishwashers go through a short drain cycle first, then fill, then wash, etc. In this case, let the dishwasher go through drain first (very distinct sound), then right when it started to fill (more of a hissing sound) open the door slowly and dump a gallon of vinegar in the tub. Close the door, hit the start button to continue with the rest of the cycle.
A good alternative to vinegar is Dishwasher Magic. It’s a little more expensive than vinegar, but does a better job, including leaving a better smelling dishwasher. It’s also much better than citric acid because it comes in a liquid form.
