Kitchen care guide
How to clean a dishwasher without guessing
A model-aware method for the filter, spray arms, door edges, and machine-care cycle—plus the signs that call for an appliance technician instead.
Jump to Steps
The short answer
Clean the filter first, inspect the spray arms, then run the care cycle your manufacturer recommends.
Avoid improvising with acids, bleach, or mixed cleaners. Your model’s manual is the authority on removable parts, safe products, and cycle settings.
Diagnose before scrubbing
Let the symptom choose your first check
Odor, grit, and film can point to different maintenance needs. Start narrow instead of throwing every cleaner at the machine.
A sour or stale odor
Filter, standing debris, and door edges
Clean removable parts, then run the manual-approved care cycle.
Grit on clean dishes
Filter seating and spray-arm clearance
Rinse the filter, reinstall it securely, and check rack loading.
Cloudy film inside
Detergent or mineral residue
Use the manufacturer’s cleaner or descaling instructions—not a mixed DIY solution.
A safe cleaning sequence
How to clean a dishwasher in six steps
This order follows common manufacturer guidance while leaving model-specific removal, cleaner, and cycle decisions to your care manual.
- 01
Start with the manual and an empty machine
Unload every rack and find the care instructions for your exact model. Confirm whether the filter is removable, which cycle is intended for machine care, and which cleaners the manufacturer approves.
Why first: filters, finishes, and cleaning cycles vary by model.
- 02
Wipe the door, edges, and gasket
Use a soft damp cloth and mild soap where the manual permits. Focus on the top edge, side channels, handle, and gasket—areas the main wash spray may not reach. Keep water away from controls and electrical openings.
Skip abrasive pads and bleach-based products unless your manual specifically permits them.
- 03
Remove and rinse the filter
Pull out the lower rack. If your filter is removable, unlock it exactly as the manual shows, rinse it under running water, and use mild soap with a soft brush for stubborn debris. Reinstall it firmly before running the machine.
Whirlpool warns against wire brushes and scouring pads, which can damage filters.
- 04
Inspect the spray arms
Spin each arm gently to confirm it moves freely and check the openings for visible debris. Bosch recommends running a removed arm under water when the manual allows removal, and using a toothpick to loosen material caught in a blocked opening.
Do not force an arm, enlarge a hole, or use sharp metal tools.
- 05
Run an approved machine-care cycle
With the dishwasher empty and the filter back in place, follow the package and appliance directions for a dishwasher cleaner, descaler, or built-in machine-care program. Use the prescribed cycle and never combine cleaners.
When directions conflict, the appliance manual wins.
- 06
Reset the habits that cause buildup
Scrape large food scraps, load racks so water can circulate, keep tall items from blocking the spray arms, and clean the filter when the manual or indicator calls for it. You do not need to hand-wash dishes before loading them.
A short maintenance routine is more useful than an aggressive rescue clean.
Good maintenance moves
- Use the model manual and approved products.
- Use a soft brush or cloth on removable parts.
- Reinstall the filter securely before a cycle.
- Keep spray arms clear of tall dishes.
Stop and get appliance help
- Standing water returns after the filter is clear.
- The machine leaks, sparks, smells electrical, or trips a breaker.
- A filter, pump cover, or spray arm will not release as the manual describes.
- Poor washing continues after maintenance and correct loading.

FAQ
Dishwasher cleaning questions, answered
Straight answers about filters, vinegar, spray arms, maintenance timing, gritty dishes, and professional cleaning scope.
How often should you clean a dishwasher?
Follow the schedule in your model’s care guide. Whirlpool recommends cleaning the dishwasher about every 30 days for optimal performance, while Bosch recommends cleaning filters and spray arms every few months. Usage, water hardness, and the appliance design can change that cadence.
Can you clean a dishwasher with vinegar?
Only if the manufacturer’s instructions allow it. Whirlpool describes an occasional vinegar cycle but cautions that repeated acid exposure can damage a dishwasher. A manufacturer-approved dishwasher cleaner or built-in machine-care cycle is the safer default when the manual is unclear.
Where is the dishwasher filter?
On many models, the filter sits at the bottom of the tub beneath the lower rack. Some filters twist out; others are fixed or maintenance-free. Check the owner’s manual before pulling, turning, or prying any part.
Why do clean dishes still feel gritty?
A dirty or incorrectly seated filter can let food particles recirculate. Crowded racks, a blocked spray arm, or a wash-cycle issue can also contribute. Start with the filter and spray-arm checks in the manual; if the problem continues, contact the appliance manufacturer or a qualified technician.
Should you take the spray arms off to clean them?
Not unless your model’s instructions explain how. You can inspect the openings in place, and Bosch notes that a toothpick can loosen visible debris in blocked holes. Never force an arm or use metal that could scratch or enlarge an opening.
Can a house cleaner clean inside the dishwasher?
