If this is in the drain lines, then there is a small amount of build up, which will happen over time. Watch to insure that the water is draining and not starting to go slower indicating a stopped up line. If this is the water line, look at the water coming out. If it is discolored or frothy air may be mixing in, probably from a problem on the side of the municipality supplying the water.
Yes. Your dishwasher discharge hose is probably hooked into the side of the disposal. Running your disposal will not hurt the dishwasher.
i think the "swishing noise" you mean is casued by the belts turning on the puleys , you can check this by squirting a little wd40 on the belts as its running and the noise should go away for a short time .
If your dishwasher has self cleaning filters, there is no need to clean them. If not, you can do it yourself. Cleaning the filters is important to keep it in good condition. There is no need to clean it often. The hot water and detergent will dissolve most or all food particle. Donβt ignore the filters either. They sit snug right below the wash arm. Most are made of aluminum and can be pulled up to clean. Others need to be unlocked first. The most important thing to remember is BE GENTLE. Aluminum bends easy.
I've read in several places that pouring vinegar down the dishwasher drain (a lot) and then running the empty dishwasher will kill the ants and keep them from coming back.
It should only be steam.
Your dishwasher may have a leak. Look under it with a flashlight just after it's finished a wash.
Consider boiling them or running them through your dishwasher.
It depends on your wants as well as your budget. An energy-saver will save you money washing dishes in the long run - especially if you are running the dishwasher every day.
It depends on the electricity tariff in your home.
Only running the dishwasher when it is full can help to reduce and electricity bill that is high. When the dishwasher is run too frequently it can use large amounts of power and water, which can raise electricity bills quickly. In order to lower the bill, wait until the dishwasher is full before running it. This may mean that several days pass until it is run, or only running it once per week. If this is not frequent enough, consider hand washing dishes that are needed in the meantime to have clean dishes without having to run the dishwasher regularly..
Assuming you're running the dishwasher fully packed, then handwashing the same number of dishes would consume more water. Yet if you are running the dishwasher with not to much silverware it would save water to just hand wash them.
I suggest running the dishwasher with detergent and about a quarter cup of laundry bleach. Let run the full cycle at high heat. Even if a dishwasher is not used often there is still moisture in it, the black is most likely some type of mold.
