Step 1: Disconnect the dishwasher.

It is critical to turn off the dishwasher and unplug it from the power source before beginning the cleaning process. This ensures that no electrical current is running through the machine, making it safe to use and clean.

These filters can become clogged with grease and other materials over time, reducing the dishwasher’s efficiency. To clean the filters, remove them from the dishwasher and wash them in hot, soapy water. To remove any stubborn grease or debris, use a scrub brush. Before putting the filters back in the dishwasher, thoroughly rinse and dry them.

Before putting the spray arms back in the dishwasher, thoroughly rinse and dry them.

Step 5: Clean the dishwasher’s interior.

After cleaning the filters and spray arms, it’s time to clean the dishwasher’s interior. Wipe down the inside of the dishwasher with a clean cloth or sponge, paying special attention to the corners and crevices where dirt and debris can accumulate. To remove stubborn grease or grime, make a solution of hot water and detergent. To remove any remaining detergent or debris, thoroughly rinse the interior with hot water.

Step 6: Clean the dishwasher’s exterior.

It is a good idea to run a cleaning cycle after cleaning the dishwasher to ensure that any remaining debris or bacteria are removed. Fill the dishwasher halfway with hot water and add a commercial dishwasher cleaner or a hot water and vinegar mixture. To ensure that the cleaning solution is effective, run the dishwasher on the hottest cycle possible. When the cycle is finished, open the dishwasher and let it cool for a few minutes before closing it again.
