Your dishwasher filter is an important part of the appliance’s function. It catches the tiny leftover bits of food still on your dishes when they enter the dishwasher, allowing the dishes to get completely clean during the cycle. Self-cleaning dishwasher filters will include tiny garbage disposal that grinds up any large pieces and doesn’t need to be manually cleaned as often, but these dishwashers also tend to be louder and use more energy. Even so, it’s easy for a customer to overwork the filter and treat it as a legit garbage disposal which in almost any design, these are simply meant for any scraps of food that was not discarded into the trash or garbage disposal to keep the dishwasher pump clean of debris.
Manual dishwasher filters are much like the screens you put in the bottom of your sink and will eventually need to be cleaned out so that your dishwasher works properly. You’ll know when your filter needs cleaning when you start to notice gritty dishes, puddling in the bottom of the dishwasher, or an unpleasant smell from otherwise clean dishes.
Sometimes, your dishwasher filter may even break from heavy use or non-food shrapnel in the wrong place. When this happens, you’ll need an all-new filter and knowledge on how to replace it. Which is exactly what we’re here to provide today. Whether your dishwasher filter is broken, dirty, or just need looking at, here’s how to do it:
If your dishwasher filter is broken or your dishwasher manual suggests replacing at intervals, you’ll need to find the correct replacement filter. There are two ways to do this.
First, you can use your dishwasher’s make and model to look up the correct replacement part. Second, to be absolutely certain, you can take a look at the filter and find the serial number indicating the exact part you should order. Once you know the filter you need, order it online or pick one up at your local hardware store if available.
Collect the supplies you need before starting the repair. No one enjoys running for a needed tool halfway through the job. Fortunately, the number of items you need for this repair is incredibly limited. All you need on-hand is a screwdriver and your spare filter. Or just a screwdriver if you’re washing your old filter instead. For washing, you will of course also need a sink and some cleaning solution. You may also want a towel nearby in case of drips.
Any time you’re opening up the innards of an appliance, always disconnect the power. If you can’t reach your dishwasher’s wall plug (and most homeowners can’t) then switch the power off at the kitchen breaker. This way, there is a zero risk of accidental electrocution or the mechanism trying to run while you work on it.
Start by removing the bottom rack of your dishwasher so you can reach the dishwasher floor. This is where the water drains and, therefore, where your dishwasher filter will be.
On the floor of your dishwasher, you should find a circular cover over a cylindrical slot. It may even have the word FILTER embossed in the plastic to make this item easier to find. If you’re not sure, check the manual for your model of dishwasher.
Now that you’ve spotted the dishwasher filter, your next step is to remove the cover. Many dishwasher filter covers will just snap right off on little plastic clips, but yours might have screws holding the cover in place. If so, carefully remove those screws and set them aside. You’ll need them later.
Grasp the filter cover from one edge and pull. It should pop right off the filter housing. Set the cover aside out of the way.
Underneath the cover should be a small cup holding the dishwasher filter. The cup may have a tab or a handle. Pull out the cup, but not all the way as it is connected to the drain hose.
Pull the filter out of its drain housing cup. If there is another screw, remove it and set it aside with the others.
If your filter is reusable and in good shape, now is the time to clean it. Use dishwashing liquid, a sponge, and possibly a toothbrush to get all the little particles out of the filter. Rinse with very hot water and pat dry with a towel.
If the filter is broken or non-reusable, it’s alright to throw it away before installing the new one.
Whether you have a new filter or a newly clean filter, place it back into the drain housing cup where the filter was removed from previously. Make sure to set it in until it settles or clicks.
Before you reassemble, make sure the water line connected to the bottom of the cup is firmly secured. Leaks here can cause real problems later if not prevented now.
Set the cup back into place and press or twist until it clicks into the housing. Each dishwasher model may be different so do what your dishwasher seems to expect. Re-fasten screws if there were any securing the drain cup.
With the cup in place, grab the filter cover and snap it back over, facing the same direction it was before.
If there were any housing screws securing the filter, grab them now and put them back into place. Secure tightly so swirling water can’t shake them loose.
Finally, you are ready to test your dishwasher to see if your repair was a success. Start by turning your breaker back on, then run an experimental load of dishes with a little food still left on them. If your dishwasher drains correctly and the dishes are sparkling clean, then your repair was picture-perfect. Congratulations.
