How to Take Apart Dishwasher to Clean: A Step-by-Step Guide
Unplug the dishwasher and remove the racks. Detach the spray arm by unscrewing or unclipping it. Clean the filter located at the bottom. For deeper cleaning, unscrew the bottom panel to access and wipe the interior parts.
Preparing to Disassemble the Dishwasher

Gather Necessary Tools
Before you start, it’s important to have all the right tools on hand. You’ll need a screwdriver, a pair of pliers, and a soft brush or sponge.
A towel or a piece of cloth will also be useful for laying down on the floor to catch any water that may spill out when you’re working on the dishwasher.
Unplug and Disconnect the Dishwasher
Safety first! Always unplug your dishwasher from the power source before starting any maintenance. This prevents the risk of electric shock. Additionally, turn off the water supply to the dishwasher to avoid any potential leaks while you’re working.
Empty the Dishwasher
Make sure the dishwasher is empty. Remove any dishes or utensils that are still inside to prevent them from getting damaged or becoming an obstacle as you clean the interior components.
Remove the Racks
Slide out the racks from the dishwasher to access the interior more easily. This will give you better visibility and reach to all the components that need cleaning. Set the racks aside in a safe area where they won’t get in the way.
Accessing the Spray Arms
Locate the spray arms inside your dishwasher. These are usually found at the bottom and sometimes at the middle or top. You may need to unscrew them or simply unclip them, depending on your dishwasher’s design. Take note of how they are fitted so you can easily put them back later.
Cleaning the Interior Components

Removing and Cleaning the Filter
At the bottom of your dishwasher, you’ll find the filter. This is a crucial component that traps food particles and debris.
Twist or unclip the filter to remove it, then wash it thoroughly under running water. Use a soft brush to remove any stuck-on grime.
Taking Out and Cleaning the Spray Arms
Once you’ve detached the spray arms, rinse them under water to remove any loose debris. Check the holes where water sprays out for clogs.
If you find any blockages, use a toothpick or a small wire to gently remove them. Wash the spray arms with warm, soapy water to ensure they are completely clean.
Cleaning the Dishwasher Tub
With the racks and spray arms out, you now have full access to the dishwasher tub. Use a damp cloth or sponge to wipe down the walls and the door.
Pay special attention to the bottom of the tub and the area around the drain where gunk tends to accumulate.
Checking and Clearing the Drain
Inspect the drain at the bottom of the dishwasher to ensure it’s not obstructed. Remove any debris you find to prevent future drainage problems.
If necessary, for more extensive cleaning, unscrew the bottom panel of the dishwasher to access the drain and give it a thorough clean.
Reassembling the Dishwasher

Replacing the Spray Arms
Once the spray arms are completely dry, reattach them to their respective positions inside the dishwasher.
Make sure they are securely fastened, whether by screwing them back in place or clipping them on, to ensure proper function when the dishwasher is running.
Installing the Filter Back into Place
After cleaning, reinsert the filter into its housing at the bottom of the dishwasher. Make sure it’s correctly positioned and locked in place to prevent any damage during the dishwasher’s operation.
Putting the Racks Back In
Slide the racks back into the dishwasher carefully, ensuring they are on their tracks and sit flush within the dishwasher. Check that they move smoothly and don’t obstruct the spray arms or the closing of the door.
Reconnecting the Dishwasher
Once everything is back in place, reconnect the water supply and plug the dishwasher back into the power outlet. Make sure the power cord and water hose are not kinked or damaged to avoid any issues when the dishwasher is in use.
Testing the Dishwasher After Reassembly
Run a short cycle without dishes to ensure everything is working correctly. Listen for any unusual noises and check for leaks.
If everything sounds and looks good, your dishwasher is ready to tackle your next load of dirty dishes with increased efficiency!
