7 Best Solutions To Unclog A Dishwasher

How To Fix A Clogged Dishwasher

To unclog your dishwasher, gather all the necessary materials needed and then follow these simple steps:

#1: Check And Test Your Garbage Disposal

The first step when troubleshooting a clogged dishwasher is to check if your garbage disposal is working correctly. If not, the blockage could be coming from there and will need to be cleared before you can unclog your dishwasher.

To do this, plug in the garbage disposal and turn it on. Observe if it is making any noise. If it’s not, turn it off and unplug it before attempting to clear the blockage.

#2: Get Rid Of The Water Inside The Dishwasher

If there’s standing water inside your dishwasher, use a bucket or other container to scoop out the water. You may need to do this several times until all the water has been removed. It would be easier for you to detect where the blockage is if the dishwasher is empty and dry.

#3: Inspect The Sink’s Air Gap

The air gap is located on the top of the sink beside the faucet. It is a device that prevents water from backing up into your dishwasher. Inspect it to make sure that nothing is clogging it.

To clean the air gap, take off its cover and rinse it with hot water. If you find any debris, use a toothbrush or brush to get rid of it. You can also pour some vinegar down the air gap in order to dissolve any bits of food that may have been stuck inside.

#4: Get Rid Of The Gunk From The Drain Basket

Get Rid Of The Gunk From The Drain Basket

The drain basket is located at the base of the dishwasher and collects food debris and small items such as buttons, coins, etc. Inspect it to make sure that nothing is clogging it. If you find any debris, remove them with a pair of tweezers or by hand.

You can also use a drain snake to break up the debris and make it easier to get rid of. If the problem persists, replacing the drain basket may be a good idea.

#5: Check The Drain Hose

Ensure that food debris or foreign objects don’t clog the drain hose. Check it for any kinks or blockages, and ensure that it is properly connected to your dishwasher and garbage disposal. If the hose has any damage, replace it immediately.

#6: Clean The Dishwasher Filter

The dishwasher filter is located at the bottom of the dishwasher. It collects food debris and other small particles, which can clog the machine if they are not removed regularly. Clean it with a soft brush or cloth and rinse it thoroughly with hot water to remove any debris.

#7: Use A Vinegar and Baking Soda Solution On the Drain Pipe

If all the above steps fail, you can try using vinegar and baking soda solution. Pour one cup of white vinegar down the drain pipe and wait for fifteen minutes. Then add one cup of baking soda and allow it to sit for another fifteen minutes.

Finally, rinse it with hot water. This should clear any blockages in the pipes and help unclog your dishwasher. If this fails, it may be time to call in a professional appliance technician for assistance.
