You should clean or replace the dishwasher filter when a lot of food particles block the flow of the water. The filter is instrumental in the cleaning of the dishes, glasses and flatware. If your dishwasher is not performing the way it should, you may find that the dishwasher filter is clogged. In some models of dishwashers, the filter can be cleaned a few times before it must be replaced. Other manufacturers recommend replacing the filter annually.
Step 1 - Locate the Dishwasher Filter
The dishwasher filter is going to be located at the bottom of the inside basin. Most of the time you'll find it under the drain cap in the center of the wash area. It may be off to the side on some models. A quick look at the service manual or the inside of the dishwasher will help you find it quickly.
Step 2 - Purchase the Correct Filter for Your Dishwasher
Before you buy the new dishwasher filter, make sure you know what type to get. Some dishwashers use a triple-layer helix filter, while others use extra-fine filters. Take the information on your make and model to the appliance store and order the correct filter.
Step 3 - Turn the Power Off
Your home may have the dishwasher connected to the kitchen circuit breaker or to one all its own. However yours is configured, turn the breaker off at the circuit. This will ensure the dishwasher is not accidentally turned on while you are working on it.
Step 4 - Remove the Filter Cover
There are two ways the filter cover may be secured to the dishwasher. The first is with a top cover that simply pops off. The other way is through a cover that either screws off or is held down with two screws. Determine which type you have in your dishwasher and remove the cover.
Step 5 - Remove the Old Dishwasher Filter
You will see a cup the dishwasher filter sits in. Grab the handle of the cup and pull straight up. The cup will bring with it the filter and the water line. The dishwasher filter sits in the cup and will come right out.
Step 6 - Clean Out the Filter Basin
If the filter is clogged with small food particles, there is mostly likely going to be some around the cup and basin. Clean this out with a sponge or a rag.
Step 7 - Replace the Dishwasher Filter
Set the new dishwasher filter into the cup assembly. Make sure the water tube is still connected tightly to the cup. Place the assembly back into the basin and snap the cup back into place.
Step 8 - Replace the Cover
Position the cover back onto the housing. Secure it by the screws or through popping the top back on.
Step 9 - Turn the Power On and Run the Dishwasher
Turn the power back on to the dishwasher and run it through a full cycle. Check the dishes to make sure they are clean of any food particles.
