How to Unclog a Dishwasher from the Bottom Up.
The bottom of the dishwasher is often a hidden and forgotten part of the appliance. This is where all the debris settles, leaving you with a clogged dishwasher. Here are some steps to help you unclog your dishwasher from the bottom up.
Check to make sure that there isn’t anything blocking your drain hole at the bottom of your dishwasher. If your sink doesn’t have one, there’s a good chance that your dishwasher doesn’t either. If there is something in the way, use a spoon or measuring cup to push it out of the way.
Put on rubber gloves before beginning this process so that you don’t leave any grease or residue on your hands.
Use a sponge to remove soap scum and food particles stuck in crevices around the inside of your drain pump assembly. You’ll need an open-ended wrench or pliers to loosen and remove this assembly from your sink. It may take a few tries before it comes loose.
How to Unclog a Dishwasher
Once you’ve removed the drain pump, use a sponge to scrub away any remaining soap scum and food particles. Rinse the sponge off when you’re finished.
Use a hose to flush the unit of water. This will help clear out any debris that’s loosened while removing the drain pump assembly.
If you still have problems with your dishwasher, it may be necessary to replace the entire pump assembly if it’s broken or defective.
Where to find your drain pump assembly
Once you’ve removed your sink’s drain pump, use an open-ended wrench or pliers to loosen and remove the black rubber flange. This is located just above the sink’s drain hole.
Using a dishwasher brush, scrub away any debris that has accumulated in this area. Rinse the brush with hot water before using it again, if necessary.
Replace the rubber flange back on your sink and tighten it with your wrench or pliers. Make sure that it is snug enough to prevent water from leaking down into the dishwasher when you run it through its cycle.
Tighten all the bolts on your dishwasher with an adjustable wrench or a ratchet set so that they can’t come loose during use.
Wipe up any excess food particles, grease or soap scum with a paper towel before running your next cycle. Finally, rinse out your sponge in hot water and hang it up to dry so that you can use it again later in the week.
Removing the assembly from the sink
Once you have the assembly removed, you will see a screw on the bottom of it. Remove this screw before proceeding with any other steps.
Next, remove the lower spray arm from your dishwasher. The arm is held in place by two screws. Each screw has a white and a black cap that must be unscrewed in order to remove it. Once both screws are removed, the arm can be pulled out of the dishwasher.
Now that the spray arm is removed, you’ll need to disconnect one of its leads to get at it more easily and gain access to where it’s connected to the inside of your drain pump assembly. There are two connections here—one is on top, while the other is on the side. Disconnect them both, then remove any rubber gaskets or sealing washers that may be holding them in place.
Next, remove all metal parts from your bottom rack or basket (it can also be found near your sink). You may need a flathead screwdriver or hex wrench for this step as well as any other tools required for specific models.
Finally, use pliers to undo all of the bolts holding your drain pump assembly into your sink base so that you can pull it.
Using a sponge to remove soap scum and food particles
Use the sponge to scrub around the inside of your drain pump assembly. When you’ve finished, use some warm water and a bit of dish soap to remove any remaining traces of food or soap scum. Make sure that you rinse out your sponge so that it doesn’t become a breeding ground for mold.
Gently loosening the drain pump assembly.
Next, use a spoon or measuring cup to loosen the three screws at the bottom of your dishwasher. Gently rotate the drain pump assembly until it’s free from the sink, being careful not to remove it completely.
Use a dry cloth or paper towel to wipe down any grease or residue that could have come out of the drain pump assembly.
Now you can replace your old, clogged filter with a new one and put your handy work back together. When you’re done, make sure you tighten everything back up again and run your dishwasher through its normal cycle to get rid of any excess water before turning it off for the night.
