It is not unusual for a dishwasher to have difficulty in draining. It can have multiple causes but for your search on; “Why is my dishwasher not draining properly?”, we will look at the possibilities and their solutions one by one.
Why Is My Dishwasher Not Draining Properly – Solutions
1. Garbage Disposal:
Your garbage disposal unit connects to your sink as well as the draining hose of your dishwasher. It may be that your garbage disposal contains some food left overs or other large particles which may have come from the kitchen sink or from the dishwasher.
Just run some water through the garbage disposal unit and check if it is unclogged or not. If this helps then good, otherwise we move to the next step.
2. Air gap:
Some dishwashers, which are not connected to the sink through a garbage disposal unit are connected through air gap. It is a small unit which is placed right beside your kitchen faucet. It has one connection with the drain hose of your dishwasher. The air gap usually makes sure that the dirty or used water does not go into the dishwasher through back flow.
To check the air gap, twist it anti-clockwise and release it and see if it is clogged. Clean the air gap by running water and rubbing a stiff brush and place it again. Now check if your dishwasher drains. If not, then we can move to the next step.
3. Clean the drain basket and drain pump:
The drain basket is usually present at the bottom or on one side of the machine. It has a cover which looks like a basket placed upside down. Inside it is the pump which it is supposed to protect.
The drain basket can be usually removed easily by twisting it to a side or it may be fixed by a screw or two. It shouldn’t be too difficult to remove your basket to check if it contains debris or not.
If you find debris (like food particles) inside the basket, simply put them out with the help of a fork or a spoon or whatever feels best. Then check if the parts of the pump are okay.
You can check the blade by trying to turn it. You should know easily if it is stuck or not. It should move without making you feel that you might break it, otherwise it means that there’s a problem.
Sometimes, the pump is run by a belt. Check if that’s the case with your dishwasher. If there is some difficulty in making the pump work, check if your belt isn’t worn out. If it is, then you should replace it.
4. Check the drain hose:
The drain hose can stop the water from flowing by two means.
One is that it is clogged. You need to make sure that your drain hose is unclogged. You can check this by running some water through it.
The other is that it may be kinked badly. Check if the hose is bent wrongly, and if it is, then correct it.
Also check if your hose isn’t worn out (Bad bents can cause damage to the hose easily).
5. Clean your machine:
If you have made it this far then it is better that you clean your machine. The procedure is the same as we discussed in our other article on how to get rid of the smell from your dishwasher.
To do this, you can scrub the parts you have opened with a paste of baking soda, dish soap and water. Make sure to thoroughly scrub the interior of the machine. After that, you can also scrub the drain hose of your machine.
Now put the parts back in their positions and run an empty cycle at the hottest temperature available in the machine. This should rinse the paste out of your machine.
Now, your machine should be clean and unclogged. Check if it drains as it should.
