Let's get right to the point: Drano should never be used in a dishwasher because the harsh chemicals in Drano will damage the plastic parts of the appliance and could leave toxic residue on your dishes.
The dishwasher drain must be connected before the P-trap, not after it, which is what was done here. With this improper installation, sewer gases have the potential to come back in to the dishwasher.
There are several common causes of a dishwasher backing up into a sink, including a block in the air gap, an obstruction in your dishwasher or a clogged garbage disposal. One of the most likely culprits is a simple sink clog.
When the drain is clogged, pressure in the pipe can cause water to back up into the dishwasher. To alleviate this problem, you can try and remove the P-trap underneath the sink and clean out the gunk. Don't forget to put a water bucket under the pipe first!
Pour one cup of fresh baking soda down the drain, followed by one cup of white vinegar. Place a rubber stopper or other sink hole cover over the drain opening. Wait 15 minutes to allow the vinegar and baking soda to unclog your drain, Then take out the drain cover and run hot tap water down the drain to clear the clog.
The plug is located right inside the nipple where the drain hose from the dishwasher attaches to the disposal. If it's not removed, the dishwasher can't drain properly. If the plug has been removed, it's possible the disposer is clogged with debris. Clear out the drain tube from any obstructions.
The food, grease, dirt, and hair that accumulates in your sink pipes will eventually find their way to this main line. If the gunk builds up into the drain line, coating the inside of the pipe, the water flow can become restricted and backs up into your sink.
Do not exceed 10 feet distance to drain. Do not connect drain lines from other devices to the dishwasher drain hose. Dishwasher must be connected to waste line with an air gap (not supplied) or 32" minimum high drain loop, depending on local codes and ordinances to prevent back flow into the dishwasher.
At the end of the main wash, all of the water is drained. Depending on the cycle, the main wash can take anywhere from 20 to 60 minutes, and may repeat multiple times throughout the cycle duration.
Fill a dishwasher-safe bowl with 1 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.
"Using vinegar and baking soda are easy, effective ways to clean inside a dishwasher, but do not use them together at the same time—clean with the vinegar first and then with the baking soda."
If you are experiencing the bathroom sink not draining properly but the pipes appear to be clear, there may be a blockage in the drain. This can happen if there is a build-up of soap, hair, or other debris over time. If left unchecked, this can eventually cause wastewater to back up and flood your bathroom sink.
That black substance that keeps seeping into your sink or toilet is usually bacteria that's clinging to waste in your drain lines. This bacteria tends to grow and spread over time, particularly because the matter that goes down these drains is organic in nature, providing a food source for the bacteria to live on.

Since it is common for debris to get stuck in the dishwasher drain, try cleaning it with a solution of equal parts baking soda and vinegar. Pour the baking soda and vinegar into the bottom of the dishwasher and let it sit for 15 minutes. Then run a rinse cycle at the highest heat setting.
While the baking soda and vinegar solution is effective in breaking down a clog, it will also cause your drain to become more damaged. The baking soda's abrasive nature will wear down your drain over time. This is why you should avoid using baking soda and vinegar solution for cleaning out your drain.
Plunge away the blockage
Fill the sink with hot water until it's about halfway full and creates a seal around the drain. Position the plunger over the drain and begin pumping up and down quickly several times. Remove the plunger and wait to see if the water drains. Repeat the process until the water drains freely.
Using a snake is also more invasive and time-consuming than using a chemical cleaner is, and can often become a dirty job. When it comes to getting at and removing major clogs or clogs that are deep down in your pipes, however, a plumber's snake is your best bet.
