9. How often should you clean a dishwasher?

Clean a dishwasher by washing its removable filter, clearing the spray arms, and wiping the tub, door, and seal. Use the cleaning method in your manual, then run an empty cycle if the manual allows it.

This routine covers the interior, not just the drain hose. Before cleaning, switch off the dishwasher if your manual calls for it, and avoid mixing cleaning products.

How do you clean a dishwasher step by step?

Clean from the parts that catch debris to the surfaces that collect residue: remove and rinse the filter, check the spray arms, wipe the interior, then run an approved cleaning cycle.

1. Remove dishes and racks if needed for access.
2. Take out the filter as the manual directs, then rinse it.
3. Check spray-arm openings for debris and clean them as instructed.
4. Wipe the tub, door edges, and seal with a soft cloth.
5. Clean the detergent dispenser and any accessible drain area.
6. Refit the parts securely and run an empty cycle if permitted.

Don't use sharp tools to scrape food from the tub or poke into a drain. If a part doesn't release easily, stop and check the manual.

How do you clean a dishwasher filter?

Remove and rinse a removable filter according to the manual. Many filters twist or lift out, but the method varies by model, so don't force one.

Clear food scraps into the trash before rinsing. Use a soft brush if the manual allows it, and check for damage before putting the filter back.

For the filter-specific steps, see how to clean a dishwasher filter. If you're unsure how the assembly comes apart, follow how to remove a dishwasher filter first.

A replacement may be relevant if your filter is cracked, missing, or no longer fits correctly. If you have a Bosch, compare Bosch dishwasher replacement parts for compatible options.

Check the part number and appliance compatibility before ordering.

For a Whirlpool model, use the model-specific guide to how to clean a Whirlpool dishwasher filter. Filter shapes and removal steps vary, even among machines from the same brand.

How do you clean dishwasher spray arms?

Check the spray arms for blocked openings and clean them as your manual allows. Food or mineral buildup can interfere with the water jets.

Remove an arm only if the manual explains how. Rinse it and clear visible debris gently; don't widen an opening with a pin or other sharp object.

Follow how to clean dishwasher spray arms for more detail. If you need to take an arm off, see how to remove a dishwasher spray arm before you start.

How do you clean the dishwasher tub, door, and seal?

Wipe the tub, door edges, detergent dispenser, and rubber seal with a soft damp cloth. These areas can hold splashes and food residue that a wash cycle may not remove.

Use only a cleaner the manual permits. Avoid abrasive pads and harsh chemicals unless the manufacturer specifically recommends them, and wipe away any cleaner residue.

Pay attention to the lower door edge and folds in the seal, where crumbs can collect. Dry the area with a clean cloth if moisture remains.

Can you clean a dishwasher with vinegar?

Use vinegar only if your dishwasher manual says it is safe for your model. If allowed, follow the manual's directions for the amount, placement, and cycle.

Don't combine vinegar with bleach or other cleaners. If you want the vinegar method, read how to clean a dishwasher with vinegar and check it against your appliance instructions.

Do replacement filter cups help with cleaning?

A replacement filter cup is useful only when the existing part is damaged or due for replacement, and the new one matches your dishwasher. It doesn't replace routine cleaning of the filter and interior.

Cenipar's W10872845 filter cup is described as washable and compatible with some Whirlpool and Kenmore dishwashers. Verify your exact model and replacement part number before choosing it.

AMI PARTS also offers a W10872845 filter cup for compatible Whirlpool, Kenmore, Amana, and KitchenAid models. For other compatible options, see KitchenAid replacement parts.

Confirm the part number, shape, and fit for your appliance before ordering.

What should you do if the dishwasher still smells or drains poorly?

Check the filter, spray arms, and accessible drain area again, then review the manual's troubleshooting steps. If water remains in the tub or the problem continues, contact the manufacturer or a qualified technician.

How often should you clean a dishwasher?

Inspect the filter and interior regularly, and clean them when buildup appears. The right schedule depends on use and your model's instructions.

Scrape large food scraps from dishes before loading, keep the filter seated, and wipe visible residue before it hardens. Before loading stainless steel items, check whether stainless steel is dishwasher safe.

See how to load a dishwasher correctly for loading guidance. A short check after unloading can help you spot buildup early.

For routine cleaning, start with the filter and spray arms, then wipe the tub and seal. Replace a filter only when it is damaged or the correct maintenance step calls for it.

Frequently asked questions

How often should you clean a dishwasher?

Check the filter and interior regularly, and clean them when you see food buildup, residue, or odor. How often depends on how much you use the dishwasher and what goes into it.

Follow the manual for the filter cleaning schedule and any parts that need special care.

Can you clean a dishwasher with vinegar?

Use vinegar only if your dishwasher manual permits it, and follow its directions for where to put it and which cycle to run.

Some manufacturers advise against vinegar because it can affect parts. For a targeted guide, see our instructions for cleaning a dishwasher with vinegar.

Why does a dishwasher still smell after cleaning?

A lingering smell can come from food or standing water around the filter, drain area, spray arms, or door seal.

Clean accessible areas according to the manual and check that the drain hose is positioned as instructed. If odor or drainage trouble continues, contact the manufacturer or a qualified technician.

Should you clean a dishwasher filter?

Yes, clean a removable filter as often as the manual recommends, since trapped food can affect drainage and leave residue.
