How To Clean A Dishwasher Filter: A Safe Step-by-Step Guide

Cloudy glasses and a sour tub usually point to one overlooked part. A clogged filter lets dirty wash water spray back across the load, so the machine seems to run while the dishes stay gritty. Learning how to clean a dishwasher filter takes about ten minutes on most machines, and it does not require taking the appliance apart. This guide covers a safe home method for Metro Atlanta kitchens, plus the point where a full kitchen reset is a better job for a cleaning crew.

Why the filter matters before you start

The filter sits at the bottom of the tub and catches food before wash water is sprayed back onto the dishes. When that screen packs with rice, grease, or a stray label, dirty water recirculates through the spray arms. The plates can look washed and still feel gritty, which is why people often blame the detergent first.

The Whirlpool filter-care guide says the upper assembly keeps large objects and fine particles out of the pump, while the lower filter keeps food off the dishes. The same guide says not to run the machine without the filters locked in place, because that can damage the dishwasher.

That is a maintenance task, not a whole-kitchen clean. If baseboards, the inside of the oven, and the fridge also need a reset, the deep cleaning service covers built-up dirt a standard visit does not. Use this article for the filter itself.

Check the manual before you twist anything

Filters are not identical. Some twist a quarter turn and lift out. Some pull straight up. A few machines hide a second screen under the first cup. Guessing is how clips break.

Look up the model number on the door edge or the side of the tub, then follow that maker's removal steps. If you cannot find the manual, search the model number plus "filter" on the manufacturer's site. Stop if the part does not release with light hand pressure.

Two safety notes matter more than speed:

• Turn the dishwasher off and let it cool if it just finished a hot cycle.
• Do not run a cycle with the filter left on the counter. The pump can be damaged.

GE's owner guidance for its removable filters is the same idea: remove the filter, rinse it, and put it back before the next wash. Treat the manual as the authority for your model. This article is the general method.

How to clean a dishwasher filter, step by step

Work at the sink with a towel ready. You only need warm water, a drop of dish soap, and a soft brush such as an old toothbrush. Skip steel wool, scouring pads, and wire brushes. Whirlpool specifically warns that those can damage the filter mesh.

1. Empty the bottom rack. Pull out the lower rack so you can see the tub floor. Remove any bones, labels, or glass before you touch the filter.
2. Find the filter. On most newer machines it is a cylinder or flat screen in the center of the tub floor. Older machines may have a screen at the back of the floor.
3. Remove it the way the manual describes. For many Whirlpool models that means turning the upper assembly a quarter turn counterclockwise and lifting it out, then lifting the lower filter slightly and pulling it forward. Other brands unlock with a tab or a lift handle.
4. Rinse loose debris first. Hold the filter under warm running water until rice, seeds, and grease film rinse away. Knock the open end against your palm over the sink, not over the tub.
5. Brush the mesh gently. Use a soft brush and a little dish soap on stuck-on soil or hard-water film. Work from both sides of the screen. Do not poke holes through the mesh.
6. Rinse until the water runs clear. Soap left on the filter will foam in the next cycle. If the mesh still looks gray, rinse again rather than scrubbing harder.
7. Dry and reseat it. Shake off water or pat the plastic frame with a towel. Set the lower filter first, then lock the upper assembly. If the top piece spins freely, it is not locked. Run a short rinse cycle with the racks empty and listen for a rattle.

Stop and reseat the filter if you feel resistance while locking it. Forcing a crooked filter is the usual cause of a leak at the tub floor.

How often to clean it, and the signs it is overdue.

Whirlpool recommends cleaning the filter about once a month with regular use, and about every two weeks if the household runs the dishwasher daily. That is a useful starting point, not a rule for every kitchen. A home that rinses plates first can go longer. A home that loads saucy pans every night cannot.

What you notice.	What it usually means.	What to do next.
Dishes feel gritty or spotted.	Food is being sprayed back onto the load.	Clean the filter before changing detergent.
A sour smell when you open the door.	Grease and food are sitting in the screen.	Rinse the filter and wipe the tub floor.
Standing water after the cycle.	The filter or drain path may be blocked.	Clean the filter. Call a technician if water remains.
You can see debris in the cylinder.	The filter is doing its job and is full.	Remove and rinse it the same day.
The kitchen needs more than the appliance.	Cabinets, floors, and the oven are past a quick wipe.	Request a deep-clean estimate for the room.

A clean filter will not fix a failing drain pump or a cracked spray arm. If water still sits in the tub after the filter is clear, that is an appliance repair, not a cleaning step.

Model differences that change the job

Manual-clean filters are the ones this guide is for. You remove them and rinse them. Some machines advertise a self-cleaning filter that uses water flow to grind or flush particles. Those still collect large debris, and many still have a screen you should inspect. If the manual says the filter is not user-removable, do not pry it out.

Hard water in parts of Metro Atlanta leaves a chalky film that warm water alone will not clear. A soft brush and dish soap are enough for light film. If the mesh is crusted, soak the plastic filter in warm water for ten minutes, then brush again. Do not soak it in bleach, and do not put it in the oven to dry.

Apartment and rental kitchens add one extra check. Confirm the filter is the original part before a move-out inspection. A missing or swapped filter is a common reason a landlord flags the appliance. Clear Choice's kitchen cleaning guide covers the counters, sink, and appliance exteriors around that handoff. It does not replace this filter procedure.

If the mesh is torn, bent, or will not lock, stop using the dishwasher and order the correct replacement for that model number. A close-looking part from another brand often sits crooked. That is how water leaks under the machine and how food bypasses the screen. Write down the model before you shop so the new filter matches the tub, not just the door color.

Grease film is different from hard-water scale. Grease smears and smells. Scale looks chalky and stays put after a rinse. For grease, soap and warm water are enough. For light scale, a ten-minute soak in warm water plus the soft brush is the home method this guide supports. If the crust does not move, follow the manufacturer's descaling note rather than scraping the plastic.

What to clean around the filter, and what to leave.

While the filter is out, wipe the tub floor with a damp cloth and pick out anything sitting in the sump. Labels, pits, and broken glass belong in the trash, not down the drain. Wipe the door gasket with a cloth and plain water so mildew does not stay in the fold.

Leave these parts alone unless the manual tells you to remove them.

• The spray arms, unless you are only clearing a clogged hole with a toothpick.
• The heating element.
• Any screw that holds the pump cover.

If you want a short supply list for the rest of the kitchen, the kitchen cleaning supplies guide covers what is worth keeping on hand. For the filter, soap and a soft brush are enough. You do not need a specialty dishwasher cleaner to rinse a screen.

Sibling appliance jobs stay on their own pages. A washing machine cleaning guide and an air fryer cleaning guide answer those machines. Do not reuse those steps here. Filters, drums, and baskets are different parts.

When a filter rinse is not the whole kitchen

Homeowners and office managers usually call after the small jobs pile up. The dishwasher smells, the oven door is sticky, and the floor under the fridge has not been reached in months. A filter rinse solves one of those problems. It does not reset the room.

Clear Choice Home Cleaning Services LLC is a locally owned, veteran-owned company based in Alpharetta and serving Metro Atlanta. A deep clean is the right quote request when the kitchen needs built-up dirt removed from baseboards, cabinet fronts, and hard-to-reach edges, not just the appliance. A standard clean is the better fit when the room is already in good shape and you want it maintained.

Ask for an estimate rather than assuming a fixed price. Home size, condition, and how long the buildup has sat all change the visit. Michael A. Jones and the crew can price the kitchen after they understand the scope. They will not guess a number from a blog post.

Property managers and real-estate clients can use the same split. Have the resident rinse the filter before photos or a showing, and book a deeper kitchen clean when the whole room has to look ready. The filter step is still worth doing the morning of a turnover because a sour dishwasher is noticeable the moment someone opens it.

A simple monthly habit

Tie the rinse to a date you already remember, such as the first weekend of the month. Empty the bottom rack, lift the filter, and rinse it while the sink is already wet from dishes. The job stays short when it stays regular. Waiting until the smell shows up means the mesh is packed and the tub floor needs a wipe too.

Office kitchens and break rooms load differently from a family home. Coffee grounds, tea bags, and leftover lunch pack the screen faster than a household that scrapes plates. A manager can put the monthly rinse on the same checklist as wiping the microwave, and call for an estimate when the whole break room is past a staff wipe-down.

Keep a small towel in the cabinet under the sink so the wet filter does not drip across the floor. Shake it over the sink, not over the open dishwasher. Food rinsed back into the tub ends up in the sump you just cleared.

Frequently asked questions

Can I run the dishwasher without the filter installed?

No. Whirlpool warns that operating the dishwasher without the filters properly installed can damage the machine. Put the filter back and confirm it is locked before you start a cycle.

How often should I clean a dishwasher filter?

About once a month is Whirlpool's general guidance for regular use, and about every two weeks if you run the dishwasher daily. Clean it sooner if dishes come out gritty or the tub smells.

What should I use to scrub the filter?

Use warm water, a drop of dish soap, and a soft brush. Do not use a wire brush or scouring pad. Those can tear the mesh and let food back into the wash water.

Why do dishes still look dirty after I clean the filter?

Check that the filter is locked, that spray-arm holes are clear, and that you are not overloading the racks. If standing water remains, the drain may need a technician. A dirty kitchen around the machine is a separate cleaning job.

Does Clear Choice clean inside dishwashers on a deep clean?

Ask when you request the estimate so the scope is clear. This guide is the do-it-yourself filter method. A deep-clean visit is for the broader kitchen, and the quote will say what is included.
