Step 1: Empty the dishwasher

Before you do anything else, start by emptying the dishwasher. If you had loaded dishes in the machine, gently remove them all and store them in a safe place. Emptying the dishwasher will make it much easier to unclog the drain line. It will also prevent the chance of damaging the dishwasher and your dishes. Also remove all the racks, including the bottom one to make it easy to access the drain line.

Step 2: Unplug the dishwasher from the wall socket

Once you have removed all dishes from the dishwasher, the next step is to unplug it from the wall socket. This is a very important step that most people usually overlook. If you fail to disconnect your dishwasher from the wall socket then you risk being electrocuted while unclogging the drain line. Electrocution can result in serious injuries that could be fatal. Your safety comes above everything else. So, make sure you unplug the dishwasher before you start unblocking the drain line.

Step 3: Drain stagnant water in the dishwasher

You will discover that there is a lot of stagnant water in the dishwasher. This is because the drain line is clogged, thus making it difficult for the machine to drain water. Remove all stagnant water from the dishwasher then dry all moisture using a dry dish towel. This process will not only make it easy to fix the clogged drain line but it will also protect you from slips and falls when unclogging the drain line.

Step 4: Check the drain hose line

Now that your working environment is safe, it’s time to get to the main problem. The drain hose is responsible for draining waste from the dishwasher to the sewer line. If it is clogged, then your machine will not be able to get rid of wastes generated for the cleaning process. Inspect the drain hose to see if it is clogged. If yes, pull your dishwasher from the wall to make it easy to access the drain hose line.

Step 5: Remove the drain line to unclog it

Once you have access to the drain hose line, disconnect it from the dishwasher. Use a plier to loosen the drain hose screws to make the removal process easy. Place a dish bowl under the drain hose to trap water that spills. Once you have disconnected the drain hose from the dishwasher, it is now time to remove all debris that has clogged the drain line. This process is simple; all you need to do is use a commercial declogger to get rid of all debris that has stuck inside the drain line. If you don’t have this equipment, use a hanger wire to unclog the drain line.

Step 6: Inspect the dishwasher drain

If you notice that the drain hose does not have sufficient debris to block the line, the problem could be in the dishwasher drain. Check the dishwasher drain to see if it is clogged. The dishwasher drain is a basket-shaped device located at the bottom side of the dishwasher. Remove the dishwasher drain using a screwdriver then use a declogging tool to remove all debris that has stuck inside.

Step 7: Reassemble all parts

Once you have fixed the problem, the final step is to reassemble all parts. Start by installing the drain hose line and dishwasher drain. Use the screwdriver to secure them tightly in place. Return the dishwasher back to its place then install the racks. Complete the reassembly process by connecting the dishwasher to the power supply. Once you are done, load it with dishes, select the right cycle then press start to begin the cleaning process. Inspect the dishwasher keenly to see if it drains waste materials properly. If it works perfectly, then the problem is fixed. If the problem persists, then it means that your dishwasher has a bigger problem that can only be fixed by a professional.

Can hot water unclog my dishwasher drain line?

It is a very simple process that will take you a few minutes to complete. All you need to do is boil water and then pour it into the drain line.

Can I unclog my dishwasher with vinegar?
