How often should I clean my dishwasher?

Follow your model's manual. Check and clean a user-removable filter regularly, especially when you notice food debris or poor results, and run a manufacturer-recommended cleaning cycle as needed.

Can I use vinegar or bleach in a dishwasher?

Do not assume either is safe for your model. Use only products approved in the manufacturer's instructions, and never mix bleach with vinegar or other cleaning chemicals.

Why does my dishwasher still smell after cleaning?

Food debris, standing water or drainage problems may cause odors. Check the accessible filter, seals and spray arms, then run an approved cleaning cycle. Persistent odors or standing water may require professional service.

What if my dishwasher does not have a removable filter?

Some models use a different filtration system. Check the manual for your exact model, and never remove fixed covers or force components. Follow the manufacturer's cleaning procedure instead.

If your dishwasher has a user-removable filter, unlock it as instructed in the manual. Lift it out carefully, remove trapped food and rinse with warm water. Gently brush away buildup without damaging the mesh. Do not force parts that are stuck. Reinstall and lock the filter securely.
3. Inspect the spray arms

Check the spray-arm holes for visible debris. If your manual allows removal, detach the arms and rinse them; gently clear blocked holes using the manufacturer's recommended method. Avoid enlarging holes or damaging the nozzles. Reattach the arms and confirm they spin freely.
4. Wipe the door seals and edges

Use a damp microfiber cloth with a little mild dish soap to wipe the door edges, rubber seals and detergent dispenser exterior. Remove crumbs and grime from folds gently. Avoid abrasive pads, excessive water near controls and pulling on the seal. Wipe again with a clean damp cloth.
5. Clean the interior and run an approved cycle

Wipe visible residue from the tub and drain area without removing fixed covers. Ensure the filter and spray arms are fitted correctly. Run the machine empty using its self-clean cycle or the hottest suitable cycle recommended by the manufacturer, with an approved cleaner only if instructed. Never combine cleaning agents.
6. Check operation and prevent buildup

After the cycle, check for leaks, unusual noises and remaining debris. Clean the filter at the interval stated in the manual, scrape excess food from dishes, and keep the spray arms unobstructed. Allow the interior to dry only in a way that is safe around children and pets. Seek service for persistent drainage faults or leaks.
